battery charger

I picked up a AAA NiMh battery charger. The label reads: Output: 1.2 V 800 mA AA/AAA charging: 120 mA

Why the two different current specs? Does not compute -

Smaller batteries overheat more easily...

If the power output is at 1.2V, it's charging cells in parallel. If it delivers 800 mA into a 1.2V load, that's good for six cells in parallel? The 120 mA could be a per-cell limit, or into a 1.4V -1.6V load (fully-charged cell)

The first spec is for intended cell type.

Just guessing that the 1.2V 800mA is the battery rating and the 120mA is the charging current.

Maybe charges AA at 800mA and AAA at 120mA ?
