  • Seems to be good quality
Size: 1 Count (Pack of 1) Style: 12 AH
I order my AA and AAA batteries from this company so figured their my best shot for LifePO4 battery. My charger showed 12.4 Ah when I put it on the charger so must have been pretty empty but at least I know capacity checks out. Will see how it holds up!

My grandkids love to ride there toddlers cars on our country spread. Batteries don’t last long. This one did the job

  • It's good
Size: 1 Count (Pack of 1) Style: 18 AH
I don't have a bunch of technical specs for this. Seems like a good quality battery. I plan on putting this in a small DIY solar generator for camping or other outings. I'm playing with solar and this seems to be a great choice.

  • Small for 18Ah
Size: 1 Count (Pack of 1) Style: 18 AH
This battery arrived with 12.3 volts. It's about the size of my 12Ah batteries, though noticeably heavier. The battery charged quickly with my 30-amp charger. I don't have a great way to test capacity yet, but the battery does seem to last a while.

  • Lightweight with Plenty of Power
Size: 1 Count (Pack of 1) Style: 12 AH
Battery as described, capacity as expected. This lithium LiFePO4 battery has a lot of power in it and charges well on my fish finder. It is a quite upgrade to previous lead acid battery. It charges fast and lasts for a long time, although it’s small and light. If you have boat electronics, I highly recommend this battery! ... show more

  • Perfect fit
Size: 1 Count (Pack of 1) Style: 12 AH
I bought this LiFePo4 battery to replace the battery on my mobility scooter. The new battery is easy carried around, charges well and doesn't heat up at all, and best of all, I can take my scooter out on trips in a much lighter way! Now I’m quite happy with my decision!
