No.2 is the Eco Worthy 280Ah Lithium battery. No.3 is a left-field option (and cheapest option) – connecting 3 100Ah Kepworth Lithium batteries in parallel! The 4th best option is the LiGen 12V 300Ah Lithium Leisure Battery. To be clear: all batteries on this list are the modern LiFePO4 (Lithium Iron Phosphate) batteries.
Lithium-ion batteries have high energy densities. Duracell and Energizer are known for long-lasting alkaline batteries. Panasonic Eneloop AA batteries are notable for rechargeables due to their low self-discharge. To extend battery life, store in a cool, dry place. Avoid exposing to extreme temperatures since heat can reduce lifespan.
Because Lithium (LiFEPO4) batteries offer a ton more power, longevity and ability to handle deep discharge than Lead-acid batteries. The new LiFePO4 batteries even solve the safety issues that plagued earlier incarnations of the Lithium battery. In fact, the evidence suggests they’re now even safer than Lead-acid batteries.
Shop around for AA and AAA batteries and the main types you’ll find are alkaline and lithium disposable batteries. Lithium batteries last a lot longer in more energy intensive devices. We've found that they can give you 2-3 hours more power than an alkaline battery. But they're also much more expensive.
Lithium batteries have the longest lifespan of all deep-cycle batteries, lasting 3,000-5,000 partial cycles. As we covered earlier, lead acid battery options don’t even scratch the surface of that kind of longevity. In fact, lead acid batteries typically only last 500 -1,000 partial cycles.
