Description

Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store What charger do I need? Is one included? This battery requires a LiFePO4 (lithium iron phosphate) charger, and a charger is NOT included. Do not use a lead-acid charger — an incompatible charger can cause improper charging, trigger the BMS protection, or damage the battery. Will this fit a standard 7Ah slot? This is a compact, taller form factor (2.8 x 3.5 x 4.0 in), designed to replace smaller 12V 5Ah/6Ah SLA/AGM batteries — not the long standard 7Ah size. Please measure your compartment before ordering. How is this better than lead-acid? It weighs about one-third of a comparable lead-acid battery (1.65 lbs), lasts far longer (rated 4000+ cycles), and holds its charge while sitting idle — so it's ready when you need it, unlike lead-acid that often goes flat in storage. Is this really 6Ah? How long does it last? Yes. Multiple customers have verified the real capacity with capacity testers. Runtime depends on your device's draw. I've only used lead-acid. Is lithium complicated? Not at all. The main difference is the charger — use a lithium (LiFePO4) charger instead of a lead-acid one. Everything else is straightforward: same 12V system, lighter weight, longer life.

  • Great price. High quality battery
This is a great replacement for my Craftsman garage door opener that had an old lead acid battery that was 14 years old. I had to modify one of the terminals to make it fit the connector I had, but no big deal. It charged right up and has worked perfectly ever since. It weighs a fraction of the lead acid battery and has about double the energy density. ... show more

  • Better than expected replacement for old lead-acid battery.
I used two of these to replace the lead-acid batteries in a ceiling track hoist for a disabled person. The old batteries were about four years old, and the typical "alarm system" lead-acid type. These LiFePO4 batteries have the built in charge controller, so I knew it would just be a straight across swap. My hope was to have more battery capacity than the old ones so we could go longer between charges. The experience of changing battery tech was more than expected. These things have about four times the life of the old style battery. They hold voltage high during the discharge cycle, so the power level of the motor remains consistent throughout the use cycle. That means the motor is performing near peak power until right before a charge is needed. Since these batteries weigh less than the old ones, the lift is easier to pull along the track when unloaded. All good stuff. The only concern that I've got is that the charge percentage displayed by the lift's electronics is calibrated for the lead-acid discharge curve. These will read at a high level (80%-100% charge) until they're ready to die. Once you see a 70% on the screen, you've only got a few more seconds of power before it absolutely needs to charge. That's not going to cost this a star, as it's a function of the changing the battery tech that the electronics weren't built to understand. ... show more

Swapped four of these in series for two 24v lead acids in an old lawnmower. Really impressed so far, for $100 replaced $400 worth of batteries.
