Rechargeable Batteries

[stwstrz123]

Hello,

I have a Bosch rechargeable battery electric drill and the charger no longer works. A replacement charger seems to cost more than a new drill. However I have a Draper drill of the same type. Can I use the charger for the draper to charge the battery for the Bosch battery?

The battery for the Bosch is normally charged by a charger (which is the broken one) 240 volts _50 Hz/15A Input, 11,6V/560mA Output.

The Draper is 230 V "for use with Draper 14.4V Battery 240V-50Hz Input, 17V-400mA Output.

I know nothing about Hz`s and things, so please keep it simple!!

Thankyou.

The bit I'd worry about is the output. The Draper is pushing with 17v whilst the tool for the Bosch is only expecting 11.6v. That a high percentage difference.

I don't think I'd risk my Bosch tool with it. Try to find a charger that matches the Bosch tool figures.

Particularly check the output voltage, but ensure it can deliver an output of 560 mA minimum too.

230v vs 240v is nothing worth worrying about. Tolerances mean they are the same in practical circumstances.

The other thing to remember before you spend money is that the life of a drill rechargeable battery is normally two years, then they fade very quickly. I had a bosch, you could charge it for two days, but put the battery back into the drill and it would only last a few minutes.
