I have a Nimh/Nicd battery charger that charges the following batteries at the following rates is there any danger the batteries will be damaged though overcharging if left in the charger for too long ?
This charger is a very slow and old boat, there is no fear about damaging batteries.
The true modern ANSMANN AA chargers, needs mostly true batteries so to work with them.
There is so many no-name batteries with fake specs, and one powerful charger will make them toast.
I own many batteries and chargers by ANSMANN ,
Two "Energy for speed" chargers .
One " Energy 8 " battery station
And the " Digital LCD Tester "
AA 2850mah Digital
AAA 1100mah ( another mini animal )
Plus many Sanyo AA 2700 & Sanyo Eneloop.
Lots of quality, but at a price, as always.
The fast chargers haves even small cooling fans.
The bottom line is that for AA any charger who gives less than 600mA per Cell,
is an outdated toy.
All those ANSMANN uses pulses and not constant current,
they are designed to keep the batteries in top shape, by living them on those battery stations all the time.
