Why us my punk speaker battery drains easily

Yes, indeed.

I have the same trouble with yours.

I had left my punk for a long period and found that the battery lost its full charging.

Even though I charged and find that the battery got full-charge, it only announces ‘Four hours playtime’ …

So, I am now trying to exchange the battery inside.

The process is very easy.

1. with minus screw driver or some flat and tough tool, you should take rubber guard which covers the speaker

at first.

*please note that you should start the upper part and also be careful with the area around the dock covered with

rubber protector. here, the glue is put and very sticky.

2. with plus screw driver, take four screws out of the speaker.

3. put your minus driver into the clack of the speaker around carefully.

4. after you find the gap around the speaker, pull the upper part up,

*note that the glue ? was put around inside to prevent water intrusion.

5. the battery is very easy to find and remove.

*battery was stuck with rubber glue to the body inside.

*battery information : 18490 battery , 1400mAh, 3.7v

*note that the battery has two leading lines for plus and minus polar and soldered to attach the circuit.

so, you should do soldering … not difficult but you need tools for soldering.

6. the battery 18490 is not found here in Japan.

so, I am looking for the battery …. will take a long time ????

• maybe you are not worried how to purchase the battery 18490, like me.

I checked many sites to look for 18490, but all of the sites are telling that it is very easy to purchase if you are in

the States. (><)
