Yup...

Heck I regularly charge 27Ah (that's right AMP not MILLIAMP) sealed batteries with a 150mAh charger.

It takes a long time ( more than four days ) for a full charge after a long weekend at the field, but I don't have to worry about damaging the batteries as this is practically a trickle charge.

This is how I regularly charge my field box batteries, that I purchased from UPS vendors. In turn I found that the UPS's charge the batteries at this rate too.

And yes I've verified full charge and capacity with my ICE charger just to assure myself that the 27Ah battery was being fully charged.

I also charge my 2000mAh NIMH batteries with 50 & 100mAh chargers just fine too.

Also verified to obtain full capacity through actual tests.
