Long shot, but you never know!

[phillpot]

This may well get moved by the Mods but lets give it a try as I'd rather ask amongst my S friends and acquaintances than total strangers.

I didn't inherit a fortune when my old Dad passed away but I did get his cordless drill, a Bosch PSB 24 VE-2. Now knowing my Dad it would not have been abused or even much used but the battery is totally flat, green light comes on the charger when plugged in (no fault lights/code flashing) but "zilch".

So, would any of you guys happen to have one and be prepared to try charging my battery if I posted it to you or try my charger on your battery?

My daughter and son-in-law are getting into a bit of DIY with their new house and, if I can get this working, sure they'll find it useful.


Alternatively any advice on how to check/test a battery or the charger would be appreciated

Charger is a AL60 DV 2411 (7.2 - 24v)

Battery pack is 2 607 335 280

If its a ni-CAD battery then it'll be made up of individual ni-CAD cells inside the pack. A piece of pee to replace for a man of your skills Mike. Yotube has loads of vids on it.

Ni-CADs fail pretty easily.

Have you tried putting a multimeter onto the charger to see if anything is coming out of it?

I have a Bosch drill and just checked the model no, but sadly not the same.

Not sure exactly where you are Mike but anything like that I would take along to my reasonably local tool merchants and ask them to test it for me. I have had a battery pack fail (on a DeWalt) and they confirmed it. Mind you the price of a new battery was a bit of a shock!

Yes, I've done that with my cordless impact wrench because MAC wanted silly money for new one, but just trying to confirm if battery or charger fault?


One option would be buy a battery first then if it is the charger having a spare battery wouldn't be a bad idea

Yes, nothing.

but didn't know if it is load sensitive, won't put any volts out till it senses a battery in place? Am I over thinking it???

Spookily, just before reading your post, I ordered 4 of these off ebay after an electronic guru friend at work advised me what rechargeable battery cells I needed to replace very dead ones in a LED cycling light.

If your battery pack comes apart, you may be able to just build up a new set of cells for just a few quid rather than get ripped off to the tune of £50 for a new unit - presuming of course that your charger works. Perhaps you could test it with a multimeter to see if is giving the right currents or sultanas or raisins or whatever.

And by the way, I'm humbled to be offereing you advice for once....I just hope it's of some small use.

If it hasn't been used much and also not for a long time its very common that the NiMH cells have self discharged and maybe also gone into polarity reversal.
Measure the output terminals of the pack and see what voltage is there. 16 to 20 volts and the pack may be recoverable, 10 to 16 volts doubtful, below 10 volts dead.

Mine shows a voltage all the time, however you could put a load on the circuit with a 25ohm resistor or bulb in circuit with the meter probe.

Not sure about the Boshe but had a problem with a Dewalt battery. Took it to bits and they have three terminals. The third is for the temperature sensor so that you can't charge it when it's too hot or cold. So it should have a resistance to the -ve if memory serves, or there may be 4 terminals?? It is quite likely a pt100 platinum resistance probe (prt) so you can just look up the resistance at your known current temperature eg 107.79 ohms at 20deg C. If it is a thermistor you are buggered as to an actual reading.

I can't remember but I either cut the wires so there was no resistance or joined them and then it charged fine. Just had to be mindful not to charge it when hot or too cold.

All that said there should be a voltage across two of the terminals if not the cells or at least one of them are buggered.

The cost of new cells outweighed the cost of a new battery last time I looked it up. So I just buy a new drill every time with batteries.....would you like an old Dewalt to add to your collection of bits I have a few now as they never die before the batteries!!

I have one of those Bosch cube site radios , it has a charging port in it . My stuff is dewalt and Makita so I have no idea what Bosch batteries fit but happy to give them a go if you can establish its the right one . Unit is GML24v and will charge NiCd/NiMH 12-24.

Many thanks for all the offers and advice.

Decided to order a battery, should the old one come to life there's no harm in having a spare. If the new 'un won't charge I'll be shopping for a charger.
