How to redo the battery screwdriver on the network?
The accumulators on the screwdriver come into disrepair about two years later.
The engine is still quite a worker, throw out a sorry. Replacing both batteries is almost like a new screwdriver.
There is an exit.
We will need a power transformer (at the exit of about 20 to 22 V). After straightening it turns out 18-19 V.
Four diodes for rectifying current. I took diodes D 246. With the maximum allowable current 10 A. it is possible above.
By ignorance, I collected a rectifier bridge from d 226, so they immediately burned down (they have a permissible current of only 0,5A) so that the diodes are better.
And so take the non-working battery block and pull out batteries from it. We will only leave two tops (we will fasten the wires for soaring the screwdriver).
We collect a diode bridge (I found a piece of Gheetynaks, I also posted on it). In the battery unit approached just in size.
We collect a box back, connect and use. Good luck!
