i would doubt that the size of the charger capability has anything to do
with actual charge time.
the scanner should have an internal constant current charge circuit, the PSU
is just a supply to the scanner.

i would expect the charge current to be about 50mA to the batteries, so go
from there (you are correct with your formula)
capacity/charge current=hours needed)

it is quite common for the chargers in scanners to never fully charge NiMh
batteries, (i assume that's what you have.)
it won't harm the scanner, nor the batteries as such, but don't let anything
get too hot, particularly the cells.
if they do, life will be severely restricted.

use an external charger.

I'm wondering if I have the formula down correct..

Scanner with a plug in 1000 mah charger. 4 2300 mah batteries. 4 *
2300 = 9200 mah. 9200 (total mah of batteries) / 1000 (mah rate of
charger) = 9.2. So 9.2 hours? Am I using the correct formula?

Thanks.

Evan
