BT-LP-14430-400-2 Rechargeable Solar Battery Pack Of 2

These are the best solar batteries I have found. Sure, they are a little pricey...but my lights stay on most of the night. I have a lot of solar lights in my yard. These make them stay on longer than any other batteries that I have tried (and that's a lot!). You get what you pay for with these little guys.

So far so good. I bought these to replace some original 250mah rated ones in the same size with the hopes of extending the operating time of some solar lights. They have met my expectations so far and I thought the price was reasonable for lithiums. There's some poor reviews on these and maybe I just got a good set, but I think the issue that disappoints people with solar lights is that they need a long day of full sun to maximize run time. The batteries aren't magic and if you don't have enough light to charge them fully, you'll get limited use. For some solar lights with very small solar cells, even with full sun, you may not have enough charge output to take advantage of the higher capacity battery. If you have your lights in a shady area, you probably won't get the run time you hope for. You need full Southern exposure for the best results. If you don't have that, solar lights may not be for your regardless of the batteries. I think that is why there are mixed reviews on these. In my experience with these, I have gained some run time on nice sunny days, but not so much when it's cloudy or overcast. The particular lights I'm using have a solar cell about twice the size of many you see. At least in theory, the larger the cell, the more it's charging capacity. But keep in mind, the charge rate on all of these is very very small. I think these are decent batteries but they may not cure your issues. The size of the solar cell and the amount of sun the installation gets is key to how well solar lights work.

Unless something strange happens that prevents these batteries from working a good long time, they instantly lit up some solar lights my daughter gave me. I see they are rechargeable except I do not have a charger for this kind of battery. I have rechargeable batteries for just about everything else but these kind of batteries!

These batteries work fairly well but my solar lights don't stay lit for the full 6 hours.

They are the Original Equipment Battery and they hold their charge very well. I have several lights that use this battery and if and when I need to replace the batteries I hope these are still available.

I have been searching for weeks for this type of battery, finally I found it here, The price is a bit steep but since it is the one I needed for my backyard lighting I went ahead and ordered them. My item arrived quickly and upon arrival I placed them in my solar lights and they immediately lit up, They have continued working for several days now with no issues, so far I am happy with my purchase.

Junk. I wish i could give them zero stars. I just moved to a new house that has some (seemingly) very nice solar lights. I thought it would be wise to give all the lights fresh batteries. They've been installed for over a week now (I gave them time to charge up). The lights go on at dusk and shut off about 2-3 hours later. I expected them to light up until dawn like my old lights did (from my old house). one of them doesn't work at all (and it worked with the old battery). This battery is the exact match to the old ones that were in the lights so I don't think the lights are at fault. I installed them all at once (bought a bunch) and I wish I hadn't so I could return them. Buyer beware.

Perfect fit for our outdoor solar lights, and is much cheaper than buying them at Home Depot or Lowes. Just make sure you select the right battery serial number so they fit correctly for your lights. Will be buying again!
