18650 Battery 2 Packs 3.7V 2600mAh Flat Top Battery for Flashlights, Headlamps, Doorbells, Toy Cars Blue

Excellent price for this rechargaeable battery. I have a Serene Soundbox that up and died on me. Spent forever making sure all the cables hadn't come loose, pairing it again to my TV and a bunch of other diagnostics suggested in the Troubleshooting but NOT once did it mention that there was a rechargeable battery. I felt like an idiot. I had done a deeper dive into why it wasn't working and someone in a forum mentioned checking the battery. Didn't even know there was one. Ordered the battery, let the unit charge for 4 hours and Voila!!! Like a brand new Soundbox. Saved myself $150!!! Very happy with these batteries.

Worked great rechargeable

Does not last. Not recommended. I replaced with a different battery and it has lasted longer than these did. Its not the solar charger it was installed in.

Decent battery I guess for it being a 2600 mah or whatever they just aren't the longest lasting charge on a vaporizer but think I just need a higher mah for it

Bought for a hair trimmer that wasn’t working anymore. I actually dug it out of the garbage along with the charger. Took it apart (that was the hard part) removed the old battery that was the second hardest, soldered in the new battery, put it back together and put a charge on it now it works perfectly! Beats spending $100 for a new one.

Acorde a lo que necesitaba

The batteries were a perfect fit, and still operating months later
