The Best Battery for Your RV | SolarKnowHow

RV Battery by Renogy

Just in case you’re wondering why anyone would need to read an elaborate article on the best RV battery; we should probably point out that finding the best RV battery might be the only difference between; whether you thoroughly enjoy your RV experience (especially when you’re off the grid) or whether it feels you with such deep seethed misery that you decide never to do it again (by ‘it’ we mean going off the grid with your RV – or even driving the RV at all)

Face it. Electricity is the life and bane of human existence. Okay, it may not be that serious, but it surely is a basic need; and you cannot entrust the task of providing electricity to just any battery. So, here is a collation of our top recommendations on the market, as well as a few tips and tricks for navigating the market and finding the best RV battery.

Battery Tender Lithium Battery

Manufacturer: Battery Tender
Model: BTL35A480C
Weight: 20 pounds
Dimensions: 6.5 x 3.4 x 5.1 inches

For an RV battery that weighs merely 20 pounds, the Battery Tender BTL35A480C packs a surprising punch – however, in contrast to the manufacturer’s claim that it produces five times more power and life than the typical lead acid battery (minus the acid), it doesn’t deliver in terms of durability – mainly if used for extended periods at a time.

Notwithstanding, the battery delivers a few thousand deep cycles until it reaches 20% – as well as fits easily into most RV battery boxes thanks to its foam spacers and Quad terminal configuration feature that allows it to be mounted in virtually any direction.
To top things off, it is lightweight and doesn’t stall because of its cranking power. It certainly doesn’t need any liquids or gels – thereby eliminating the safety hazard often associated with using batteries that require such liquids.

Lightweight – and still packs a punch

Dimensions lower its chances of fitting in a big battery box.

Odyssey PC680 Battery

Manufacturer: Odyssey
Model: PC680
Weight: 15.4 pounds
Dimensions: 7.9 x 7.8 x 3.8 inches

One of Odyssey’s biggest perks is its ability to withstand extreme temperatures and its vibration resistance feature that protects the battery chassis from vibration-related shock and extends durability.
The battery also delivers on the manufacturer’s promise to recharge quickly – and boasts one of the most rapid recharge efficiencies of sealed lead batteries on the market.

It has a long cycle life and yields up to 400cycles even at 89% discharge depth. Overall, the Odyssey is an excellent buy except for the small deception you’ll find in its ad that suggests that you might need to buy L terminal adapters separately – well, if you do, you might have an additional set of L terminal adapters because – surprisingly, the battery comes with its adapters.

This is a dry cell battery – which often means easier maintenance.
Provides up to 70% longer cycle life when compared with other deep cycle batteries
No need to purchase terminal adapters.
