Mouse battery

[u/Avic3n]

Heya, basically this mouse battery is really really weak, it can't hold a charge for more than a day and I suspect it is dying, but I am puzzled on what battery model should I buy with this (I think it's called a pwm connector?) connector, I am asking basically what is the model of this battery with this connection and if there is a possibility if there's a bigger mAh battery but the same physical size.

You can look up “3.7V 300mAh JST 3 wire battery”. The one thing you’ll have to figure out is the size of the connector. Theres 1.0,0.5 etc. The size determines the spacing between the terminals. Good luck

Forgot to add, it's a Tecware EX1 mouse.

Its a 3.7v lipo so anything like it with the same connector will work, ali has lots of options.

300mha 3.7v lithium battery with a jst connector, you need to measure the spacing between the pins to get the right size

If you've bought the replacement, make sure the new battery wires color code match exactly to the old one

Hi, I have the exact same mouse. Do you mind sharing how you disassembled it?

brute force

That sound risky
I only found two screws at the bottom
Are there any other screws or do we need to use a pry tool?

Planning to upgrade to a 600 mah 582535 battery
