Many higher power solar devices use this battery in many designs. Many of these devices can be restored to their original operation at a fraction of replacement cost by using this fine product. I highly recommend the product!

I used this LiIon battery to replace one on a portable very small drill and it fits and works great.

After some trial and error (by me) I finally got the correct batteries for my exterior solar lights. So far they work great! They are lower mAh than the originals but only 2400 vs 2600. They still do what I need. The people at Battery Junction were amazing. Very patient, very helpful and understanding. Great customer service. I will buy again!

Battery performs great. But you shipping absolutely sucks!! Even though I went the cheapest shipping it should have came quicker than it did. Other than very pleased with the product.
