12V 6Ah Rechargeable Battery, 12 Volt Deep Cycle LiFePO4 Lithium Battery 2 Pack, for Liftmaster 485LM/ 8500W/ DJW12-4.5 or Chamberlain 41A6357-1/ B970 Garage Door Opener (F1 Terminals)

I bought this battery 2 pack to upgrade my dead Rayovac 6V Ni-Cd lantern style battery in my deer feeder. The lithium batteries always outperform nickel cadmium batteries in freezing weather I've known that for years with trail camera batteries, so having a rechargeable lithium battery was my only choice. I'm glad I bought these I honestly wasn't sure how long they'd last so buying a 2 pack was ideal, the value for the money eas insane compared to buying multiple regular batteries, and the mAh rating on these absolutely destroys the standard lantern batteries. I also have a solar panel attached to the feeder to recharge the battery. After installing 1 of these batteries after doing a full DC charge at the house the 1 battery lasted all the way though 3 months of winter weather, rain, freezing, heat, and daily use putting out corn at my hunting spot. It never skipped a best and I guarantee stillness a charge today. I'd definitely buy again if needed these batteries seem very durable and should hold up well for years to come. Only longevity testing will tell! They're the same size as the standard 6V lantern batteries they replaced, fit and function exactly as intended, and even look nice though that doesn't matter once it's inside the battery box cover in my feeder!

These batteries have a built-in charger they come with a USB cable and they last and last and last and does not take long to fully recharge very satisfied I would buy these again.

Fit my door lifter perfectly. Great 1 for 1 replacment for the lead acids.

The rechargeable battery is working well. One did refuse to work after charging, but did eventually start working. I have been using them in hand held lanterns and they are lasting a long while without needing recharging. So far I am satisfied with them, but I will update this review when I have had them for longer.

I got this for my garage door opener back up battery. Only have used it once, but I bet I could get 2-3 openings and closings with it. Better than the battery I had before.

Very good replacement batteries for my Coleman Lantern. Recharge is quick and good for several hours.

I fully charged the battery and then put it on a battery tester set to 15A discharge. This would be only half load since this battery was advertised as having a 30A BMS. It failed after about 5 minutes of operation. Would not take a charge. BMS would not reset. Output voltage of only about 8.5 volts under no load. Drops to 0 volts when any load is applied. This was returned under warranty. This battery was noticeably heavier than the 7AH batteries that I've purchased previously. It's likely that it did have 10AH cells in it. Unable to measure its actual capacity because it failed before the load test completed.

The latern style batteries are no longer sold locally. This option worked well. We charge one use the other then switch them out when needed. We use them in our automatic chicken door.
