FAQs

What size battery does my car need?

The right car battery depends on your vehicle's group size, cold cranking amps, and reserve capacity requirements. Check your owner's manual or your current battery for the group size, then use our Battery Finder to confirm the right Full Throttle option for your make and model.

Are AGM batteries good for cars?

Yes. An AGM battery is an excellent choice for modern vehicles and one of the best options for drivers who want dependable power. The sealed absorbent glass mat design has no spillable electrolyte solution, no regular maintenance, and delivers superior performance compared to a conventional battery. Fullriver's AGM handles the high-current demands of start-stop technology, modern charging systems, and heavy accessory loads without the higher upfront cost of lithium batteries.

Do I need a special charger for an AGM car battery?

Yes. A sealed lead-acid battery like AGM performs best with a smart charger that has a dedicated AGM mode, delivering the higher charging voltage AGM needs during bulk and absorption stages, then dropping to a lower float voltage once the battery is fully charged. A basic trickle charger without an AGM setting can undercharge or overcharge your battery over time. See our smart charger for AGM battery guide for a full breakdown.

Can I replace my OEM battery with an AGM battery?

Yes, and many drivers do. An AGM replacement battery is a direct upgrade for most OEM battery fitments. Fullriver's Full Throttle Series covers nearly every common group size, and the pure lead plates handle the demands of a modern vehicle. Confirm your fit with our Battery Finder before you buy.

How does an AGM car battery hold up in cold weather and short trips?

Fullriver AGM batteries are built for it. The pure lead plates and lower internal resistance let the battery accept a charge quickly during short trips, unlike a standard battery that struggles to recover from partial recharges. The sealed design also handles high temperatures under the hood, giving you long battery life for daily commuters and weekend drivers alike.

Joey Whitaker wins races with Full Throttle Battery

These batteries are proven to help make more power

Joey Whitaker here, owner and driver at Whitaker Drifting. On the team, I have both my LS1 G35 and supercharged VK56 G35 powered up with Full Throttle Batteries as well as my 1000hp Supra street car. These batteries are proven to help make more power. Where standard batteries will have a voltage drop under a load the Full Throttle Batteries held voltage through any and all use. We made more consistent power than ever going to these awesome batteries. What impressed the team the most was last year in a pro-am comp we lost the alternator right before comp started. But the Full Throttle Battery kept enough voltage to get us through the top 32 and top 16. Made it to the top 8 and we got eliminated at that point. Was still able to drive the car on the trailer and back into the shop. Installed a new alternator and fired right up with no issues. A normal battery would have been done within minutes under these conditions. If you have any doubts about Full Throttle you need to throw them away and get what you need! You won't be disappointed!
