I don't have the chargers on timers, what I did was cut the plugs off and put right-angle plugs on and plug them into switchable plugs. I just turn them on when I need to use them, and turn them off when they're not in use. I thought about a timer but it seemed more logical to have them on switches. I could have just left them as-is and plugged them in and unplugged them when needed, but that seemed silly. I didn't want to keep plugging them in, unplugging them, and so on and so on. Switches were a better choice.
The 6-port charger they have is kinda timer-like, it'll charge one battery at a time, going around in a circle until they're all charged, then basically randomly keep them trickle-charged. After a certain amount of time it shuts itself off. I was thinking of getting that charger but then decided that buying the tool kits with the chargers was enough, and that putting them on switches would be the easiest and smartest thing to do.
Just some of the little weird tricks I do to stuff to make it all easier to work with. Like cutting the cord super-short on my palm sander, and adding a male plug end to it. Was getting absolutely sick of trying to wind up the cord and stuff it into the case, was easier to have a little stubby cord and use an extension cord with it.
