I  built this Solar Battery Charger for 12V Batteries some time back

Charged a 210AH Deep cycle battery that I use in the house with the Solar set-up (there was several days of power cut and the Sun was abundant!)

Fixed FIL Powerbank

"The FIL power bank just stopped working," Esther said.
Well, it must have finished it's work ... nothing last forever anyway, I thought.

So, taken for dead it laid for days...until...

I prised it open. It took a while to get it open. The power bank casing is well designed and the parts fitted firmly together.

The circuit board as I expected contains a lot of SMD's, replacing part will be a difficult task. I noticed that the black wire that connects to the battery negative terminal is lose, could it be the culprit or it only came lose as I was trying to force the casing open?

 

It should be easy to find out. I held the wire to the battery negative terminal and used my other free hand to press the LED on off button...On came the light! I soldered the wire back in place and fitted everything back together.

 

Hopefully the power bank will give several years more of back-up power.
