    Timers for battery charging stations...

    For those of you with charging stations for your rechargable batteries, do you have timers on them, or do you just leave them on until you are there and they have quit charging?? I've got enough outlets wired in to my all purpose work bench area to have several plugged in at a time, and still have outlets for other power tools, but I don't like to leave chargers "on" except when they are doing their jobs. The Ridgid fast chargers have a fan running when plugged in, and I can't see leaving them on all the time. I'm thinking a separate timer for each charger would be best. What have you used? Price and availability info would be great! TIA!! Jim.

    Jim,

    Did you consider checking out a charger like the Triton 2? These chargers will charge NiCad, NiMH, Lead Acid, and even Lithiums. The only draw back is that they run off of 12-15VDC. I know a few people that run them off of a car battery and then just trickle charge the battery every so often to keep it topped off. These chargers will automatically stop charging the battery once it has been completely charged so it is safe to leave it hooked up for extended periods of time.

    They are typically found on RC websites but they are truely awesome. I have about six of them here that I use non-stop each and every day. Of course the battery didn't work out well for me I use a 12V 55A power supply to run them.

    Jason, sounds interesting. How do you hook up to the various cordless batteries since they have different hook ups? I've got a 35 amp Astron power supply that's just collecting dust! Jim.

    Chargers designed for NiMH batteries have a "charge termination" feature that shuts off the charge current once the battery has reached full charge. Chargers made for NiCd batteries generally do not have this function as those cells can be safely float charged beyond when they reach full charge. That's why you never want to charge a NiMH battery on a NiCd charger, as a NiMH will overheat from overcharging. However, there are chargers that will handle both, but only because they use termination circuits.

    Cheers,

    Kevin

    I was hoping to find a source of a plug in timer that you turn a knob and set the number of minutes it stays on. I have one such unit, from a long time ago. the knob acutal broke about 15 years ago or so. Put a GM radio knob on it (D-shaft) from a 2 shaft stereo. But that is only one. I may look further into the type that mounts in a switch box. I can split one electrical outlet to be contolled by 2 timers. Would only need 4 at the most, could probably get by with 2. Jim.

    I know exactly what you mean but I can only find the 15 minute wind ups when I look... I know someone must have them. I'll keep my eyes open for you.
