"Bought this battery to replace a Westinghouse 18650 2000 mah 3. 7 in a solar spot light. This UltraFire battery lasts much longer. Old battery gave about 6 hrs constant light for full day of sunlight. The UltraFire TR 18650 2400mAh 3. 7V is giving an hour of constant light for every hour of sunlight, so 12 hrs sunlight gets me 12 hrs of constant on spotlight. At least so far."
"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."
"Hi! I had to buy 2400 mAh instead of 2600 mAh, but was told that was all they had, and it would work, just wouldn't last as long. And they're working. Very hard to find these batteries; I think becaused they are un-protected. The staff are very friendly, and helpful."
"Good quality for a good price."
"I have purchased these exact same batteries from Battery Junction and have been very pleased. The proof is in the reorder pudding! And the reduced price didn't hurt either."
"Always esy to order whatever I need at A GREAT PRICE"
"Product was as said shipping was good. Easy site to navigate. Purchased from here before"
