    • Excellent value
Worked well. Original manufacturer wanted $250 for a battery for a device. I took it apart and discovered it had a battery just like this one. Fixed for $23. Excellent value

    • It worked!
The connector did not work with our solar light, but that wasn't really important. I needed two 18650 batteries that had the leads soldered on for me (I do not own a soldering gun, nor do I possess the knowledge on how to solder.. this was cheaper than buying everything and learning) I pulled the connector off and spliced the wires into the old connector, plugged it in and away we went. Our Lowes solar lighted umbrella is once again shining its sweet solar powered LED light upon us in the evenings. ... show more

    • OK Replacement Battery, but died after a couple months of light use.
I am revising my review of this battery due to its short life span. I installed this battery and it iniially played and recharged just fine. Unfortunately, even though it was only cycled fewer than a dozen times, it failed after only four (4) months. Maybe I got a "lemon" as other similar battery replacements are still going strong. Used to repair an OONZ Bluetooth speaker after splicing the original connector. ... show more

    • Charge Doesn't Last as Long as It Should
Bought battery pack to replace one in the light on brick mailbox post. It charges, but the charge only lasts a few hours, not all night like the original one did (when it worked). I wish this one would hold the charge longer.
