Universal charger for power tools ?

[sardine]

Would this item charge my collection of various battery drills, torches, and other tools that i have no chargers for ?

I want to power it from my 12 v solar battery bank or inverter.

I am not electrition BUT I would suspect you would have to remove the batteries to charge from this charger

I have a couple of these type of "universal" chargers, which are designed for battery packs used in radio controlled models. I use them for NiCd, NiMH cells and battery packs, and Li-ion ( 18650 ) cells. For one I get the 12v input from a bench power supply, the other has a built-in 240v supply. They typically will handle battery packs up to 18, 20, or 22v. The "intuitive" menus are actually rather fiddly to use.
You will need to identify pos and neg on the cells or battery packs, and connect with croc clips. Any thermal protection circuits built in to the pack will be bypassed - so I charge at very low current ( 0.2 A ), which takes a long time. This is specially important and risky with Li-ion batteries. The "cell balance" function will only work if you can get to the individual cells in a Li-ion battery pack, and connect them to the JST-XH balance socket on the Turnigy charger.

Will the charger shut itself down when charging has finished ?

Yes, after the correct menu is selected for the appropriate battery type ( NiCd, NiMH, Li-ion, etc. ), the charger will detect the fully-charged voltage peak and throttle back the current, and then shut off completely.
The chargers I use are from KO Propo, Sigma Pro-peak, and B6SAC. They all work in much the same way, and I guess the Turnigy is similar too.
The procedure is not as easy as dropping a power tool battery pack into the correct charger, but it will allow you to use one charger for diverse tool batteries, and cells for head torches, etc.
