  • Worked great for replacing old batteries in my Bluetooth speakers
Style: 3.7V-5Ah-XH2.54/2Pin
I have a lot of older Bluetooth speakers that couldn't hold a charge for more than an hour or so. The batteries in these devices decline over time and are useless after 2-3 years. My devices had 2000mAh batteries in them so I decided to double the capacity reducing the amount times the device has to be charged. These worked perfectly. The form factor was larger so I had to make a few modifications to accommodate the larger size. I had to extend the wire leading to the battery as the wire on these were two short. This was easily accomplished with a soldering iron and some heat shrink all available on Amazon. Now both devices are working and stay charged about 24 hrs. at half volume. This is a much better option than throwing these speakers away and buying new. Better for the environment and pocketbook if you know a bit about electronics. My biggest question to these Bluetooth speaker manufacturers: Why do you put batteries in these speakers that don't last at least 12 hours? Why don't they use batteries that can be easily replaced like SoundBox? Batteries accessible via a user accessible compartment... It's probably because they want us to buy another one after the life of the battery is exhausted. This is the solution to save them. ... show more
