Charger timer.

[John Bowman]

Hope this is right place to post.
The common advice seems to be unplug charger after battery is at 95% to 100%, or charger light is green.
I am not always around monitoring the charger. What about if I put a timer on the wall plug, and plugged charger into that? Set timer for 3 hours or whatever?
Good idea or not?
If yes, any advice on appropriate timer? Charger rated at 2 amp.

Shouldn’t be a problem as long as you get a quality timer that can handle the load. I have one on my swimming pool pump that turns it on for ten hours each night when the power is cheaper, and that draws 9 amps.

Its been working for about twenty years now.

That’s what I do, a timer also.

A timer on any charger is always a good idea. I use them on my cordless tool battery chargers as well as those for my bike batteries.
Be aware that some inexpensive chargers can slowly discharge the battery if the DC side is left connected.

I've put together several of these....


Charge to any SOC you desire from any starting point and also has a built in timer as a secondary shutdown.
Since it disconnects the load afterwards, there's no vampire discharge if left connected. Add a home automation outlet and you can set it to start anytime or on demand with the app.
