Optima gives dimensions of 9.38 x 6.75 x 7.69 in and SAE post terminals. Compare those details with your current battery and vehicle requirements, especially if clearance is tight or the terminals face a specific direction.
Optima describes the RedTop as suited to basic electrical demands. If your vehicle has high accessory loads, check whether a dual-purpose battery better matches its use before you decide.
Choose it when your vehicle calls for a compatible Group 35 battery and the 720 CCA rating meets its requirements. The model is not a substitute for confirming the correct size, terminal arrangement and battery type.
Weize Platinum AGM Group 35: Best for a 650 CCA AGM replacement
- 650 CCA
- 100-minute reserve capacity
- 55 Ah capacity

Its stated dimensions are 9.06 x 6.89 x 8.82 in, with positive on the right and negative on the left. Mighty Max says it can be mounted in multiple positions, except upside down, which may help when installation orientation matters.
Mounting screws are included, but a wire harness and mounting accessories are not. Check what your vehicle requires before planning the installation.
Choose this battery if the 650 CCA rating, dimensions and terminal layout match your vehicle. Its position flexibility can help with installation, but it does not remove the need to confirm the correct fit.
Interstate AGM Group 35: Best for an Interstate AGM option
- 55 Ah capacity
- AGM design
- Maintenance-free and spill-proof
- 36-month warranty
Interstate's MTX Group 35 is a maintenance-free AGM option with a 36-month warranty. Check its compatibility guide and confirm fit before choosing it.
Pros
- 36-month warranty
- Maintenance-free design
- Spill-proof AGM construction
Cons
- Dimensions are not stated here
- Verify the fit with the compatibility guide
The Interstate AGM Group 35 is an AGM battery with a 36-month warranty and a maintenance-free, spill-proof design. Interstate describes its MTX AGM line as intended for start-stop vehicles.
Check Interstate's compatibility guide before buying, then compare the battery with your original unit. The details available here do not include dimensions or CCA, so use the compatibility information to confirm those fit and performance requirements.
Interstate says the MTX design is built to meet or exceed a car's starting requirements while powering accessories. Treat that as a brand statement and verify the battery against your own vehicle's manual.
This pick makes most sense if you specifically want an Interstate AGM option and can confirm the exact fit and required specs. If you need to compare clear CCA and dimensions first, the Weize or Mighty Max entries give those figures here.
Goodyear Platinum AGM Group 35: Best for flexible mounting
- 650 CCA
- 100-minute reserve capacity
- 55 Ah capacity
- Mounts in multiple positions, except upside down

- 36-month warranty
Cons
- Cannot be mounted upside down
- Dimensions differ from several other picks
Goodyear's Platinum AGM Group 35 has 650 CCA, 55 Ah capacity and 100 minutes of reserve capacity. Its stated dimensions are 9 x 7 x 8.87 in, slightly different from several other 650 CCA options in this roundup.
The battery can be mounted in multiple positions except upside down. Goodyear gives the terminal layout as positive on the right and negative on the left, and includes screws with the battery.
The 36-month warranty adds a clear coverage period to compare. Confirm its dimensions and terminal positions against your vehicle, since the Group 35 label does not make the fit details interchangeable.
Consider it if the case dimensions work for your space and you want the listed reserve capacity with flexible mounting. Choose another battery if the slightly different size or terminal arrangement does not match your current setup.
Daakmax Platinum AGM Group 35: Best for start-stop vehicles
- 650 CCA
- 100-minute reserve capacity
- 55 Ah capacity

Match the battery type, CCA and terminal positions to your vehicle before choosing it. Similar dimensions across several batteries do not mean their terminals, fit or intended use are identical.
This pick suits a buyer whose vehicle calls for a Group 35 AGM starting battery and whose fit details match. If your vehicle uses a different battery type, follow its manual rather than changing based on the group size alone.
Optima YellowTop D35: Best for higher electrical demands
- 620 CCA
- 100-minute reserve capacity
- 48 Ah C20 capacity

Pros
- 100-minute reserve capacity
- Dual-purpose design
- Maintenance-free
Cons
- Lower stated CCA than the RedTop 35
- Check fit and battery requirements first

Optima gives dimensions of 9.31 x 6.81 x 7.63 in and SAE post terminals. The brand describes this model for vehicles with high electrical demands, including those with winches or high-demand audio systems.
This battery's lower stated CCA than the RedTop 35 does not automatically make it a poor choice. Its dual-purpose design may be more relevant when your use calls for both starting and cycling capability.
Consider the YellowTop when those needs match your vehicle and the dimensions and terminals fit. If your car needs a basic starting battery, compare the RedTop 35 and your vehicle's minimum CCA requirement as well.
Autocessking AGM Group 35: Best for a 3-year warranty
- 650 CCA
- 100-minute reserve capacity
- 55 Ah capacity
- 3-year warranty
This Group 35 AGM starting battery has 650 CCA, a 100-minute reserve capacity and a 3-year warranty. It is not intended for deep-cycle applications.
Pros
- 100-minute reserve capacity
- 3-year warranty
- Starting battery for passenger cars and trucks
Cons
- Not for deep-cycle applications
- Confirm terminal position and fit
Autocessking's AGM Group 35 is a starting battery rated at 650 CCA, 55 Ah and 100 minutes of reserve capacity. It has a 3-year warranty and stated dimensions of 9.06 x 6.89 x 8.82 in.
The brand describes it as suitable for passenger cars and trucks, and says it is not intended for deep-cycle use. The terminal is identified as NB, so confirm the exact terminal arrangement with the seller or your vehicle fit information before buying.
Autocessking says AGM construction holds acid in glass fiber mats and is designed to reduce the risk of leaks and spills. Those features may matter if you're choosing AGM, but first confirm your vehicle supports the battery type.
Choose it if the Group 35 fit and AGM requirements are right for your car. Check terminal placement carefully because the details here do not specify left or right polarity.
Odyssey ODP-AGM35: Best for SAE posts and reserve capacity
- 675 CCA
- 110-minute reserve capacity
- SAE posts
- 3-year manufacturer warranty
Odyssey's ODP-AGM35 has the longest stated reserve capacity among these picks at 110 minutes. Confirm its dimensions and left-side negative terminal work for your vehicle.
Pros
- 110-minute reserve capacity
- 675 CCA
- SAE posts
Cons
- Dimensions are not stated here
- Confirm terminal layout before buying
The Odyssey ODP-AGM35 has 675 CCA and a 110-minute reserve capacity, the longest stated reserve capacity among the picks here. It uses SAE posts, with the negative terminal on the left.
Odyssey describes the Performance Series as designed to handle increased use of onboard accessories and offer deep-cycle capability. The details here do not state the battery's dimensions, so check them before choosing it for a vehicle with limited clearance.
Odyssey provides a 3-year manufacturer warranty. Its 675 CCA sits between the RedTop 35 and the 650 CCA AGM picks, but the reserve capacity and fit should carry more weight than a single number.
Consider it if your vehicle needs a compatible AGM battery and its negative-left terminal layout works for you. Confirm case dimensions and vehicle fit before buying.
How should you choose a Group 35 battery?
Choose by your vehicle's required group size, battery type, minimum CCA, case dimensions and terminal position. Comparing those details in that order can help you avoid buying a battery that fits the group label but not the car.
Start with your owner's manual or vehicle fit information. If your current battery is available, compare its label and measure the case, then confirm the terminals sit on the same sides.
What CCA should a Group 35 battery have?
A Group 35 battery should meet or exceed the minimum CCA your vehicle maker specifies. The picks here range from 620 to 720 CCA, but don't assume the highest figure is the right choice if your vehicle calls for a different battery.
Cold cranking amps describe starting power under cold conditions. Our guide to how many cold cranking amps you need explains how to compare a battery's rating with your vehicle's requirement.
Should you choose AGM or flooded lead acid?
Choose the battery type your vehicle requires, and don't switch an AGM-equipped vehicle to a flooded battery unless the manufacturer allows it. AGM models in this roundup include Weize, Mighty Max, Goodyear and Daakmax.
AGM construction can be relevant for vehicles with start-stop systems or higher electrical loads, but it does not make every AGM battery compatible with every car. See our AGM versus lead acid battery guide for more on the difference.
Why check battery dimensions and terminals?
Dimensions and terminal positions determine whether a battery can sit securely in the tray and connect correctly. Group size narrows the search, but the measurements and polarity still need to match.
For example, several AGM picks here measure about 9.06 x 6.89 x 8.82 in, while the Optima RedTop 35 and Goodyear option have different stated dimensions. Use our car battery size guide to compare the group label with the physical fit.
Which Group 35 battery should you pick?
Choose the Optima RedTop 35 if its 720 CCA, 90-minute reserve capacity and SAE terminals match your vehicle. Pick a 650 CCA AGM option such as Weize or Mighty Max when your car calls for AGM and their dimensions and terminal positions fit.
For a dual-purpose battery, consider the Optima YellowTop D35 if its 620 CCA rating meets your vehicle's requirement. Before you buy any Group 35 battery, check the manual and compare the full fit details, then read what to know before replacing a car battery.

Frequently asked questions
What does Group 35 mean on a car battery?
Group 35 identifies a battery size class, including its general case dimensions and terminal layout. It does not mean every Group 35 battery has identical measurements or connections.
Compare the replacement battery with your current one and check your vehicle's requirements before buying.
How many cold cranking amps should a Group 35 battery have?
Choose a battery that meets or exceeds your vehicle maker's minimum CCA requirement. The Group 35 picks here range from 620 to 720 CCA, but a higher number alone does not confirm that a battery is right for your car.
See our guide to cold cranking amps for help comparing requirements.
Can you replace a flooded Group 35 battery with AGM?
Sometimes, but check your vehicle manual and charging requirements first. A vehicle designed for AGM may require you to keep using AGM, while a change from flooded to AGM can depend on the vehicle.
Our AGM versus lead acid guide explains the main differences.
How do you confirm a Group 35 battery will fit?
Check the battery group, dimensions, terminal positions and required CCA against your current battery and vehicle manual. A battery can be labeled Group 35 and still differ in height or terminal details.
Our car battery size guide covers how to compare battery sizes.
