Battery Maintenance Questions

I have Questions about charging tool batteries.  I forget at times and leave my batteries on charge for a day or two.  That's not good I know.  This last time it stayed on the charger for A WEEK.  I'll check it tomorrow but I'm afraid it's probably dead.

How do you control battery charging times?

Anyone use timers with auto shutoff?  If so what type or brand?  Only timers that I found after shutoff restarts 12 hours later.

Is there a company that makes automated battery maintenance chargers for tool batteries?

I have an old drill that was given to me with 18v battery, a fairly new Ryobi with 12v battery and new Ryobi screw driver 4v lithium.   I really like the 12v and 4v tools because they are lighter and I'm getting up in my senior ages now and weight means a lot to me.  Plus I use them for building model airplanes and around the house.

Oh, I almost forgot; I just purchased a Ryobi weed eater with 24v lithium.

Take a read of this Forum thread.

You ask a great question.  Because of the number of chargers and their differences, it's easiest to just time the amount of charging that happens.  That way, you can add different charging systems as you add or replace battery tools.

The Family Handyman thread I link to, above, includes a link to one manufacturer's timed power strip.  There are probably others, by other manufacturers, this was the one that I saw first. 

Thank you so much. 

I just Googled it and found out that Home Depot sells it for about $40.00.  I will check it out plus I live about two miles from a Home Depot.

Guess I'm spoiled; all my model airplane batteries, lawn tractor and my old truck are all hooked up to maintenance type chargers.  I just plug then in and walk away.
