Henreepow 3.2v AA 600mAh Rechargeable Battery, LiFePo4 Double A Rechargeable Battery Low Self-Discharge, 3.2v Rechargeable Batteries for Solar Lights, Wall Lantern, Solar Post Lights（AA-3.2v-600mAh）

These are very high quality batteries. Ours stay lit all night long whereas other's we've had didn't. Just make sure you give them a full day to charge the first time and that will give them a longer life expectancy.

These solar batteries were the exact size for the deck post caps. The deck and yard are bright once again!

As described. Charged up when received. Fit light perfectly. Recommend.

I ordered this set of batteries to replace a set that had 2 batteries that did not hold a charge. So far this set is working fine. Hopefully they last

Got them the next day and worked fine

One battery in the pack loses power much quicker than the other three. I moved that light to expose it to a longer period of sunshine; no change. I experimented with this for 10days. No clouds and sunny. No improvement.Used for patio lights.

We buy the solar lights from Walmart that provide 50 LED light. They are amazing with how bright they are all night long. Even at 5 am, they are still shinning, although not as bright as dark throughout the night. These replacement batteries fit in the chamber, and will last for up to a year. Good investment and value!Note, if there's a power outtage, we just bring them in the house and instant lighting! Will have to remember to take them out into the sun to re-charge.

While they seem to work fine in my solar lights, and they are the same battery size, they are is supposed to have larger capacity than the 450 mAh batteries I replaced (they don't seem to last longer to discharge) I'll admit there are plenty of other factors that could affect that. They fit fine and seem to be a decent value for the money.
