ThinkJet 2225B battery pack question

[KimH]

I have reenvigorated several batteries for ThinkJets and 9114 drives. They are not the same (2225 is NiCad & 9114 is LeadAcid)

As they are not the same, but has similar power-requirements, I made experiments similar to what you are considering here.

The short version is, both devices require the battery as a power source even with the 82059… The charger is just that, a charger. The power needed to supply comes from the batteries.

There is a lot (!!!) more power required than the charger can give.

So, one of 2 options.

Powerful external power supply - as in 5-10 amps (peak) at the voltage required
Or
Rebuild the battery from the components available, as similar as possible, to what was in the battery-pack.
