A Group 35 battery is one of the most common BCI (Battery Council International) footprints under the hood of Japanese sedans, light trucks, and crossover SUVs from Honda, Toyota, Nissan, and Subaru. The right unit needs to match your vehicle’s terminal layout, cold-cranking output (CCA, the amperage a 12V battery can deliver for 30 seconds at 0°F), and reserve capacity (RC, the minutes it can run accessories if the alternator fails), while the wrong tray or hold-down can turn any swap into a rattle-prone headache. This roundup covers ten Group 35 batteries, trays, and hold-downs suited to common swaps, dual-battery builds, and engine-bay refreshes.

Taking A Closer Look At The Options
NOCO designed this enclosure around the Group 24 footprint rather than 35, but it’s the right reference for anyone running a deep-cycle or lithium-ion pack in a marine or RV bay. The snap-top lid replaces the older screw-down strap design, so popping the cover for a terminal check takes seconds, not minutes.
You bolt it down through pre-drilled mounts, which keeps the install painless on a pontoon bench seat or camper compartment floor. Compared with the Wieland billet tray ahead in this list, the BG24 trades show polish for ventilation ports and acid-spill resistance, which is the trade-off that actually matters on a boat.
Key Advantages
- Snap-lock top swings open for quick inspection without tools.
- Pre-drilled base accepts standard mounting hardware, no extra strap needed.
- Compatible with flooded, AGM, and lithium-ion chemistries inside the case.
- Vented design helps manage hydrogen off-gassing in enclosed cabins.
- Reinforced walls resist vibration from rough water or washboard roads.
Worth Noting
- Footprint is Group 24, so it won’t accept a Group 35 battery without adapter plates.
- Lid is sealed against splash but not rated for full submersion.
Who It Suits Best
Boat owners and RV travelers who need a vented, tool-free enclosure for a deep-cycle or lithium house battery. Skip it if you’re swapping a Group 35 starter battery into a daily driver.
Consider Something Else When
The Interstate Batteries MTP-35 below is the better match for a Group 35 commuter swap, since it’s a battery, not a box.
This Wieland tray is CNC-machined (cut by computer-controlled mills) from 6061 T6 aluminum, a heat-treated aerospace alloy that shrugs off corrosion and vibration. It fits the Optima 75/35 footprint shared by BlueTop, YellowTop, and RedTop batteries with different post colors marking their roles.
The brushed finish looks right at home under a polished hood, and the included stainless hardware means you won’t chase rusty bolts at the next car show. Against the cheaper Reswish tie-down later in this roundup, the Wieland costs more but rewards you with a tray that doubles as jewelry.
Everyday Wins
- 1/2-inch and 3/8-inch billet plates resist flex under hard launches.
- Stainless steel fasteners included, no extra trip to the hardware store.
- Show-ready brushed finish suits under-hood display builds.
- Universal fit for Optima group 75/35 Blue, Yellow, and RedTop models.
Trade Offs
- Battery is sold separately, so budget for the Optima itself.
- Premium price reflects the billet machining, plain stamped trays cost far less.
Made For
Show builders and Optima owners who want a hold-down that looks as deliberate as the rest of the engine bay.
Look Elsewhere When
The Reswish Aluminum Battery Tie-Down Kit is the smarter call for a quick garage swap on a budget.
This is the textbook Group 35 swap for a Camry, Accord, or Rogue. The MTP-35 hits 640 cold-cranking amps, which gives most four-cylinder commuters enough punch to start cold without straining the starter.
Interstate built the case to match OEM (original equipment manufacturer) terminal placement, so the swap usually drops straight onto the factory tray. For most daily drivers it handles the alternator’s recharge cycle without complaint. Against the OPTIMA RedTop below, you give up spiral-cell bragging rights in exchange for a friendlier price.
Everyday Advantages
- 640 CCA covers the cold-start needs of most Group 35 commuter cars.
- 100 minutes of reserve capacity keep accessories alive at idle stops.
- OEM-style terminal layout fits stock cables without modification.
- Manufacturer coverage window listed at 30 months from purchase.
Honest Caveats
- Flooded lead-acid design requires periodic terminal cleaning in humid climates.
- Lower CCA than OPTIMA’s 800-amp RedTop for severe cold climates.
Right Fit For
Daily drivers and commuters who want a no-drama replacement battery that mirrors the factory spec.
Reach For A Different Pick When
The OPTIMA 34 RedTop below is worth the jump if you face deep winter cold or run winches or high-draw audio gear.
OPTIMA’s BLUETOP line serves boaters who want one battery that starts the engine and runs the trolling motor or cabin lights. The D34M carries both ratings in a sealed AGM (absorbent glass mat, where electrolyte is held in fiberglass sheets rather than free-flowing liquid) shell, so you can mount it on its side in a tight bilge.
The spiral-cell design resists vibration far better than flat-plate batteries, which matters on a hull that slams through chop. Set against the Interstate above, the BLUETOP costs more but delivers the deep-cycle stamina that a weekend fishing trip demands.
Useful Strengths
- Dual-purpose rating covers engine cranking plus accessory loads.
- Sealed AGM allows flexible mounting orientation in marine bays.
- Spiralcell construction dampens vibration from waves and rough water.
Points To Note
- Higher upfront cost than a basic flooded marine battery.
- Group 34 footprint, so it won’t drop into a Group 35 stock tray without checking dimensions.
Best Suited To
Boat and RV owners who want a single battery to crank the engine and run cabin accessories through the night.
Not Your Match When
The Interstate MTP-35 is a smarter buy if your vehicle needs a direct Group 35 starter swap and nothing more.
The “R” in 34R flags reverse-terminal polarity, meaning the positive post sits where most batteries carry negative. That makes this RedTop a swap-in for cars and trucks whose factory cables reach from the opposite side of the tray.
You get 800 cold-cranking amps in a sealed AGM case that shrugs off spilled coolant and condensation. The trade-off versus the standard OPTIMA 34 RedTop below is identical internals, simply flipped terminals.
Reasons It Performs
- 800 CCA delivers confident cold starts in northern winters.
- Reverse-terminal layout matches specific vehicle cable routing.
- Sealed AGM tolerates heat soak under the hood without venting acid.
- Versatile mounting accepts multiple orientations in the engine bay.
Points To Keep In Mind
- Premium price over a flooded Group 35 replacement.
- Optimized for cranking, not for deep accessory cycling.
Who Should Grab It
Drivers in cold climates with reverse-polarity factory cables who need a high-output replacement. Go for the OPTIMA D34/78 YELLOWTOP below if you also need deep-cycle stamina for winches or inverters.
Skip It When
The Interstate MTP-35 above is the budget-friendly answer for standard-polarity commuter swaps.
Bevinsee built this tray specifically for fifth-gen 4Runners, claiming fitment for model years 2010 through 2023. It mounts an auxiliary battery on the passenger side, opening up room for a winch, fridge, or camp lighting without robbing the factory starter battery.
Installation uses existing screw holes, so there’s no drilling into the firewall or chassis. That alone saves an afternoon of measuring and bracing. Compared with a generic universal tray, the Bevinsee feels purpose-built for the 4Runner crowd.
Points In Its Favor
- Vehicle-specific fit for 2010-2023 Toyota 4Runner.
- Mounting hardware included for a no-drill install on stock holes.
- Passenger-side placement keeps cables short and tidy.
- Creates space for a house battery to power accessories off-engine.
A Few Limitations
- Fitment limited to 4Runner chassis, not a universal swap.
- Year-range caveat means 2024+ models should confirm clearance before ordering.
Built With In Mind
Overland and camping 4Runner owners who want a second battery for fridges and lighting without losing cranking power.
Swap It Out When
The Reswish Aluminum Battery Tie-Down Kit is the more flexible option for non-4Runner builds that just need a universal hold-down.
The standard-polarity RedTop carries the same 800 CCA and spiral-cell tech as the 34R above, just with terminals oriented for the majority of vehicles. OPTIMA’s RedTop line has long been the hot-rod and truck favorite because it survives vibration that flattens ordinary batteries.
Sealed AGM construction means you can mount it almost anywhere it fits. Compared with the Interstate MTP-35 ahead of it, the RedTop out-cranks flooded lead-acid by a wide margin, which justifies the step up for owners who want strong starts in any season.
Notable Upsides
- 800 CCA output handles cold weather and high-compression engines.
- Sealed AGM resists spills and corrosion under the hood.
- Versatile mounting fits tight engine bays and odd orientations.
- Maintenance-free design skips the periodic water top-up.
Possible Compromises
- Designed for cranking, not for sustained deep cycling.
- Premium cost over a standard flooded replacement.
Perfect Match For
Trucks, SUVs, and hot rods running stiff starters or high-demand electrical systems in mixed weather.
A Better Fit Elsewhere
The OPTIMA D34/78 YELLOWTOP below is the smarter upgrade for winches, audio, or other heavy accessory loads.
The YELLOWTOP earns its name by being the only OPTIMA that’s a true deep-cycle battery as well as a starter. The D34/78 model adds both SAE and GM-style terminals on the same case, so it adapts to either cable layout without adapter shims.
120 minutes of reserve capacity and a 55 Ah C20 rating (amp-hours delivered over a 20-hour discharge) keep accessories running long after the engine is off. Compared with the RedTop above, you trade cranking-only focus for genuine dual-purpose flexibility, which matters in trucks running winches and amplifiers.
The Value In It
- 750 CCA plus 120 minutes of reserve capacity handle winches and audio.
- Dual SAE and GM terminals accept either cable type out of the box.
- Sealed AGM allows flexible mounting in any orientation.
- Spiralcell construction resists vibration far beyond flat-plate batteries.
- 55 Ah C20 rating supports long accessory runs without engine recharge.
Things To Weigh
- Heavier at 43.5 pounds than a flooded Group 35 of similar output.
- Premium price reflects the dual-purpose engineering.
Feature Card
The Right Fit
Owners running winches, big stereos, or other accessory-heavy electrical loads who still need a strong cranking battery. Skip the YELLOWTOP if a basic daily-driver swap is the goal.
Where A Sibling Pick Shines
The Interstate MTP-35 above is the lighter, less expensive answer for plain commuter duty.
The Group 25 RedTop is the smallest footprint in OPTIMA’s starter line, suiting imports and older Japanese bays where the stock tray was never generous. You still get spiral-cell vibration resistance and sealed AGM chemistry in that tighter box.
It’s not a Group 35 case, so confirm the tray dimensions before assuming a direct swap. Against the larger RedTop above, this version favors compactness, with cranking output that suits most four-cylinder daily drivers.
A Few Highlights
- Compact Group 25 case fits tight import engine bays.
- Spiralcell construction tolerates engine vibration.
- Sealed AGM chemistry mounts in any orientation.
- Maintenance-free operation, no water top-ups.
Where It Is Less Suited
- Group 25 footprint, so it won’t drop into a stock Group 35 tray.
- Optimized for cranking rather than deep-cycle accessory loads.
Whose Shelf It Belongs On
Owners of compact imports or vintage Japanese cars whose bays can’t accept a full-size Group 35.
Another Choice May Suit
The Interstate MTP-35 above is the safer Group 35 fitment for the majority of modern commuter swaps.
Reswish ships a complete hold-down kit: an aluminum crossbar, two 10-inch J-bolts, rubber sleeves, and a full set of washers and nuts. The blue anodized (electroplated for color and corrosion resistance) finish adds a splash of color under the hood and helps the bracket resist corrosion.
You get the parts to clamp a Group 24 or 35 battery to most factory trays, which is enough for a weekend battery swap. Against the Wieland billet tray earlier, the Reswish costs far less but leans on stamped aluminum rather than CNC-cut plate.
Well-Handled Touches
- Full hardware kit included, no separate fastener runs needed.
- Aluminum crossbar resists corrosion better than plain steel brackets.
- 10-inch J-bolts fit a wide range of factory tray depths.
- Rubber sleeves protect the battery case from over-tight clamps.
Room For Improvement
- Stamped aluminum lacks the rigidity of CNC billet trays.
- Anodized blue finish may not match subdued factory bays.
Who Will Love This
DIYers and home mechanics swapping a battery in the garage who want a complete tie-down kit without paying for billet.
Where Another Pick Suits Better
The Wieland Custom Machine tray ahead is worth the jump for show-quality builds where the hold-down is on display.
Picking The Right Group 35 Battery, Tray, and Hold-Down
Choosing the right piece starts with the vehicle, not the spec sheet. Group 35 fits many Honda, Toyota, Nissan, and Subaru bays, but terminal polarity, tray depth, and accessory loads shift the answer between flooded, AGM, and spiral-cell designs. Confirming fitment before chasing CCA numbers prevents the swap-day frustration of cables that don’t reach.
Cold-cranking amps matter most in northern climates where engines fight thick oil. Reserve capacity is the better yardstick for accessory-heavy vehicles, since it dictates how long the cabin stays powered with the engine off. CCA and RC aren’t competing numbers: a battery strong in both simply costs more because of denser plate designs.
Tray and hold-down choices often get overlooked, but they decide whether a battery lasts three years or six. A rigid bracket like the Wieland billet tray cuts vibration, while a vented box like the NOCO BG24 manages off-gassing in enclosed bays. Aluminum tie-downs resist corrosion where steel brackets would eventually seize.
Battery chemistry sets the long-term ownership tone. Flooded lead-acid is the cheapest path but needs periodic terminal cleaning in humid regions. AGM and spiral-cell batteries cost more upfront, yet they tolerate heat soak, vibration, and odd mounting angles, which suits trucks, 4Runners, and marine bays running rough.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
A common Group 35 mistake is trusting a part number without measuring the existing tray, since post height, terminal polarity, and hold-down depth all vary within the same BCI group. Buyers also tend to over-index on CCA and ignore reserve capacity, only to find the battery struggling on long accessory runs. Confirming both foot and post dimensions before the swap saves an afternoon of returns.
What The Higher Tier Buys
Premium Group 35 batteries and billet trays earn their price through spiral-cell construction, sealed AGM cases, and CNC-machined brackets. Those upgrades translate to longer service life in vibration-heavy engine bays and a cleaner look under the hood. The upgrade pays off for owners running winches, audio systems, or rough roads where a basic flooded battery would otherwise shorten its own life.
Frequently Asked Questions
What vehicles take a Group 35 battery?
Group 35 fits many Honda, Toyota, Nissan, Subaru, and Mazda cars and crossovers, including the Accord, Camry, Altima, Forester, and Mazda3. Always check the owner’s manual for the exact BCI group, CCA rating, and terminal polarity before ordering.
How many CCA does a Group 35 battery need?
Most Group 35 commuter applications run well on 550 to 700 CCA. Colder climates and high-compression engines benefit from 750 CCA or more, which the OPTIMA RedTop and YELLOWTOP lines deliver.
Can I swap a flooded battery for an AGM in the same tray?
In most vehicles yes, since AGM and flooded batteries share the same Group 35 footprint. AGM batteries charge at slightly different voltages, so a smart charger or modern alternator helps them reach full capacity.
What is the difference between Group 34 and Group 35?
Group 34 is taller and often wider than Group 35, with different terminal placement. Some vehicles accept either with adapter brackets, but most need the specific group called out in the manual.
Do I need a special tray for a Group 35 battery?
Most factory trays already fit Group 35. Aftermarket trays like the Bevinsee 4Runner tray help when adding a second battery or moving to a different chassis. A solid hold-down, like the Reswish kit or Wieland billet tray, is what really keeps the battery secure.
Wrap Up
The right Group 35 pick depends on whether you need a battery, a tray, or a hold-down, and on the climate and electrical demands of your specific vehicle. Match terminal polarity and tray dimensions first, then choose the chemistry that fits how you drive, and you’ll avoid the most common swap-day regrets. The ten picks above cover the bulk of everyday swaps, dual-battery builds, and show-quality installs without overcomplicating the choice.
