EverStart Maxx Battery CCA by Size
Cold cranking amps (CCA) measure how much current a battery can push for 30 seconds at 0°F. That’s the number that decides whether a cold truck starts on the first try.
Bigger cases hold more plate area, so Group 65 and 27 lead the range. Small sizes like the 151R are for compact engines that don’t need much.
Rule of thumb: match the CCA in your owner’s manual, then go higher if you see hard winters.

EverStart Maxx vs Plus vs Platinum AGM
In most sizes Maxx beats Plus by 50 to 150 CCA and lands close to the AGM. The AGM wins on build and warranty, not raw cranking.
| Size | Plus CCA / reserve | Maxx CCA / reserve | Platinum AGM CCA / reserve |
|---|---|---|---|
| Group 65 | 750 / 140 min | 850 / 150 min | 775 / 150 min |
| Group 24F | 600 / 110 min | 750 / 130 min | 750 / 140 min |
| H7 / 94R | 750 / 120 min | 800 / 140 min | 850 / 140 min |
| H6 / 48 | 660 / 95 min | 730 / 120 min | 760 / 120 min |
| Free replacement | 2 years | 3 years | 4 years |
| Type | Flooded | Flooded | AGM |
Pick Platinum AGM instead if…
Your car has start-stop, the old battery says AGM on the label, or the battery sits under a seat or in the trunk. Go with EverStart Platinum AGM and you also get a fourth year of free replacement.
Plus is enough if…
You drive a smaller car in a mild climate or plan to sell within two years. EverStart Plus costs less and still meets the factory CCA on most cars.
Who Should Buy an EverStart Maxx Battery
Trucks and SUVs
Bigger engines need more current to turn over. The Group 65 is rated at 850 CCA and the Group 27 at 810 CCA, the highest in the flooded EverStart range.
Cold winters
A battery gives up a big share of its starting power as it gets colder, right when a cold engine is hardest to crank. Extra CCA is your margin.
Cars with add-ons
Dash cams, aftermarket audio and remote start all draw power. Reserve capacity up to 155 minutes on the T5 gives more room before it runs low.
EverStart Maxx Battery Warranty
Walmart’s Maxx listings carry a 3-year free replacement that starts on the day you buy. If the battery fails a test inside that window, Walmart replaces it at no cost. Keep your receipt or Walmart.com order, and leave the top label intact.
Owners describe quick counter swaps. Read how it works on the EverStart battery warranty page.
EverStart Maxx Battery Care
- Hook up a maintainer like the EverStart BM1E if the truck sits for weeks
- Clean crust off the terminals with baking soda and water
- Keep the hold-down tight, since vibration wears the plates
- Recharge right after a flat instead of leaving it dead

Owners on the BobIsTheOilGuy forum report about 3 years in hot climates and 8 years or more in milder ones. Heat, short trips and parasitic drain all shorten battery life.

What size EverStart Maxx do I need?
Use the BCI group size printed on your current battery, such as 24F, 35, 65 or H6. Then confirm the fit with Walmart’s “Check if this fits your vehicle” tool on the listing.
Can I use an EverStart Maxx in a car with start-stop?
It’s not recommended. Start-stop cars cycle the battery hard and usually call for AGM. Choose EverStart Platinum AGM for those.
