RYOBI Battery Charger

With only two terminals it is not likely to be a smart charger. Nicad charge state cannot reliably be detected by terminal volts alone. The best way to tell if it is reasonably charged is when the batteries themselves start to warm up showing the power is being converted to heat rather than chemical energy.

Assume the battery is used for multiple RYOBI products .. has 4 terminals ..they must make other chargers as well .. or waste of 4 terminals

My Ryobi "Plus 1" NiMh batteries have 3 terminals. the Lithium ones have an extra two small ones. That's obviously how the charger - with 5 terminals, knows what type of battery is presented for charge.

If you look for a faster charger for that battery type, then this will need the extra terminals. Some use a thermistor in the battery pack to detect temperature rise, others use diodes for similar purposes.

Not after 'faster charge' just to be sure it's getting full charge.

Anyway ... programmed up a NiCad full charge & 24Hr trickle charge ... so will at least know it has been fully charged this time.

HI where did you get the charger from? I cant track down a replacement anywhere.

Bought new off an eBay trader.
