Or the EE power bars right nowRemember the laptop stories that made the news a few back?
A Li-ion pack has it's normal + & - wires, as well as smaller wires going from each cell to the charger so it can moniter the voltage of each cell to prevent one cell from reaching a different voltage, then getting charged overly quickly by the other cells which would make it explode. The internal circuitry in the battery covers this, you'll need to break out these wires to the new charger.So I don't see why I need charge circuitry. ..
Dunno. The charger for my Hitachi cordless stuff goes about it's business differently to the way Nicad chargers do as deep cycling Nicads is good for them (memory effect) but bad for Li ion/can shorten their life. Instead of the slow drop in performance as the battery runs down the drill or whatever will just cut out (with no warning) at a certain point. Put the battery on charge and the charger first discharges it some more/'conditions it' before charging or something along those lines. As well as the usual + and - terminals on the battery case there are also 4 other terminals (T, Ls, LE, L+) that presumably help facilitate monitoring this and thatSo in that case I can just replace the cells as they are in the nicad case and use the nicad charger if it's got charger circuitry in the lions
I that case, I'd say you probably can't use your old charger with the Li-ion battery circuitry.the charger first discharges it some more

Ni-Cad batteries are charged constant VOLTAGE, Li-ion are charged with constant CURRENT.........
