Subject: Re: Jukebox not playing very long - battery life question
From: Chris Holt (amiga2k_at_cox.net)
Date: 2003-08-22


It's very likely, but it depends on the charger. The great majority of
chargers these days "sense" when the batteries are charged and switch from
charging to a trickle. Only a very few chargers are timed anymore.

Very important to get a charger designed for NiMh batteries. Chargers for
NiCad batteries are not good to use for NiMh. As with the timed chargers,
NiCad only chargers are getting very hard to find, so it's getting harder
to go wrong. :)

Make sure you are getting a good charge, especially with higher capacity
batteries. You should have no problems leaving the charger plugged in
overnight. 2100/2200 batteries will take quite a while to charge properly
in the JB.
