  • Great Value
Great battery, works and fits as should!
Reviewed in the United States on September 2, 2026 by Bruce W. Sancomb CHt.

  • Battery life, fit, AH rating were perfect for me.
Worked in my led desk lamp that the original battery went bad in. Took off the bottom of the lamp that ballooned out from the bad battery, took the battery out. I spliced the connectors this battery came with to the original connectors and works like it was designed to. Performance, battery life, size and fit all worked well. For information it was the desktop Led lights that are rechargeable but do use USB connector. ... show more

  • Excellent battery that's well made and matches expected capacity
As listed, the dimensions are correct and, from my simple testing, the battery life is as expected for 5000mAh. The construction and quality is also as I expect for a standard general use LiPo battery, with a connector that wasn't too tight or loose (like some I've purchased) yielding excellent functionality. In the application I purchased this for, namely a handheld game console, installation was easy, but it will vary depending on what you're using it with. I believe I can count on this vendor from this experience. 5/5 ... show more

  • Good purchase, Safe Battery to replace OEMs;
So far, so good. I installed this batty in one of my headlamp lights I use nightly and usually discharge the battery down to 20- 25%. Charging has been pretty easy and this particular 3.7V Li-Ion Battery does NOT get as hot as the OEM battery that came with the headlamp. Still, be cautious and careful about making your connections (I soldered mine) and keep a close watch on everything when performing lengthy charges of >45mins. DON'T EVER ALLOW THIS BATTERY OR ANY BATTERY TO CONTINUE CHARGING IF IT'S TOO HOT TO TOUCH, OR EVEN CLOSE!!! ... show more

  • size matters.
product worked, however it is too big to replace the previous battery. Both same part number, wattage, voltage, Mh, etc etc. However this one is 2 1/4 inches wide while the original was 1 7/8ths.
