GEILIENERGY Solar Light Batteries AA 600mAh 1.2V Rechargeable for Garden Lights Remotes Mice(Pack of 20)

Got my lights working again. Great price, better than taking down and replacing the solar string lights. Be careful about the battery type, make sure you open your solar box and get the numbers off the dead battery. It's dangerous to interchange with other types.

Only charge battery to 1.38 volts. Put it back together and put out in morning to get full charged when sunny. 1.51 volts: fully charged. Only companies batteries I usein my solar lights. Use windshield gasket sealant if s solar panels if ysolar panel is not molded to the black case. Seal the hole in the back of solar panel where wire is , the hole where the wire is on the stake and where the metal post goes into the top of solar panel. You might want to poke a little whole in the bottom front of cover to let heat disapate in the summer and to let moisture evaporate.

Seems to be doing the lighting of the latern

These work great in our solar outdoor garden lights

Perfect !!!

They don't keep a charge for very long.

These days we appear driven to review a product before having had much time with the product. No worries if we all know that. This order was for a 12-pack of rechargeable batteries that I will use for my solar light LED ropes. They came with a AA-like battery that was as ordered, AA 600mAh 1.2V. Reading the previous reviews was helpful, because there appear to be two similar products: a green battery (Ni-MH) or a yellow battery (Ni-CD). Not sure the color-coding is uniform, but the battery type is important. Repeating the previous review, Ni-MH are the newer more environmental friendly product that is less caustic than the older Ni-CD. All the other aspects of these two batteries do not appear to be statistically significant: cost, lifecycle, form factor, charging time, discharging time. I did read that "memory" as in how discharged it gets before a recharge is better for the newer Ni-MH. I plan to only use on the outside solar lights, so the charge/discharge will be very consistent over the expected one year battery life (if not actually two or three years). Product arrived quickly maybe because it was Amazon Prime, maybe because y'all know this is a good product and it is prepositioned. Delivery for me was in a bubble pouch with USPS in my daily mail. The first three batteries all shipped with an adequate charge to power my LED ropes through the night on a partial 4-hour late afternoon solar charge. They arrived yesterday, so I am one day into my expected year or so of use. Not including any additional pictures or video - the product was as vendor depicted, fit the standard LED ropes, so far so good.

After a charge they are working fine.
