cordless drill battery charging
I just got a cordless drill (12v Hitachi) for the first time. Can the
battery be left in the charger continuously (like a cordless phone) so that it's fully charged at all times or would this damage the battery or charger? The only thing I know about the battery/charger is that it's a Ni-Cad battery and the charger has an indicator light that turns off once the battery is charged. Thanks. Charles Lerner |

Better chargers charge and then go into a maintenance or trickle mode.
Yours may simply shut off and stay off until you remove and replace the battery. I would check the Hitachi site and review information that may be available. Or contact Hitachi. wrote in message oups.com... I just got a cordless drill (12v Hitachi) for the first time.

I had a friend who lost his entire wood shop due to one of these "battery
chargers" that caught fire. Happen again? Probably not but I do not leave my chargers turned on. You might consider putting the charger on a line that gets shut off every nite. I always shut off my compressor line at the fuse box along with the bench outlets, every nite. Throw the breakers and lock the door. -- Rumpty Radial Arm Saw Forum: http://forums.delphiforums.com/woodbutcher/start - - - - - - - - - - - - - - - - - - - - - wrote in message oups.com...

Borg has a little timer switch you can mount in a double electrical box with
an outlet and cord. Crank in the time for a full charge, or maybe less if you haven't used the battery much, and let 'er go. Then you don't have anything to remember and there's always a hot battery waiting. Wilson wrote in message oups.com... I just got a cordless drill (12v Hitachi) for the first time.

SH Does the charger turn back on by itself after some time to "top off" the battery if you don't use the battery for a while? CL |

As someone suggested I did call Hitachi and they told me the battery can be in the charger continuously; they said it stops charging based on temperature (I suppose of the battery) and then will monitor the voltage in the battery and will begin to charge again when/if the voltage drops.
