    Bosch AL1411 faulty? 7V only...

    Battery pack is model D-70745, original batteries were 12V / 1.5 Ah NiCd. I got some Ecaps from the local electronic shop, as well as thermistors, so I will begin with replacing the resistance and thermistor on the battery pack it self, and then will experiment with capacito replacement on the...

    Bosch AL1411 faulty? 7V only...

    @73's de Edd After a bit of research, tell me if i am right, you mean that i have to play with the Blue E-capacitor on the charger side, trying to replace it with diferent values? What about the resistor and the thermistor on the battery pack, are they mandatory (thermistor is gone, and...

    Hiya, here is a picture of the resistor shunt on the batterypack itself..as for the thermal resistor...it is gone... so...what should i do now? I do not get what i am supposed to do in order to 'minimal E-cap filtering [...] added accross the +/- battery terminal'...

    Thanks for you positive/encouraging intel! appreciate it! Here are the picts of the original charger PCB backside, and my 'frankenstein like' battery pack (18650+BMS)! it works well when charging directly on the +/- of the BMS with a standard 12V SMPS... So now, all I am left to do is to...

    Bosch AL1411 faulty? 7V only...

    Ok, I got it, so my best option is to find a 14V Laptop charger and retrofit it in the original charger case for the drill battery?

    Bosch AL1411 faulty? 7V only...

    Thank you for your reply! My idea is to use the old charge as a base to charge my new batteries, as i have a bms on each battery pack, all i really need is to be able to get 14v output on the + and - metal contactors... Question is what to bypass/shunt on the original control board...

    Bosch AL1411 faulty? 7V only...

    Hiya all, I just restored a old bosch NiMh battery with Li on batteries (6x18650 with bms), battery pack charges well on external charger, but gets a max of 7V when using the original bosch charger... When reading directly on the charger, i get only 7V which makes sense... How can i get 14v...
