If I leave it plugged in for too long, will I damage the battery?

I don't think so. I've left mine plugged for more than 24 hours and it was fine!

I leave mine plugged in all the time when not in use. The battery hasn't been a problem for me.

Yes - You are correct. The battery will overheat and it can be damaged! Try using a thermostatically controlled outlet like Farm Innovators model TC3-3545 as long as the 120V receptacle (or thermostat) in the same general area as the battery.

You can leave it unplugged but the battery last 3 or 4 hour, after that it needs to be plugged so it can charge.

No. I leave mine plugged in all the time and i doesn't seem to damage anything. i've used my drill for over 8 years and it still works great!! I love it so much I bought a second drill. I lost my charger on a job site and ordered this charger to replace the lost one. Neither the drills or the chargers have worn out and my battery holds a charge a very long time. LOVE this product!!

There is no need to worry about charging time. Just insert the battery into the charging station and when the battery is fully charged the chargingstops. There is no harm done by leaving the battery in the charging station indefinitely

Overnight and then I leave it in the charger all the time except for when I'm using it. You can't overcharge it.

If you meant leaving it ON inside the car, then there's a huge possibility that the battery would explode, not to mention, it would possibly fry some components in it. That's why I replaced the battery with a super capacitor.

Yes, that would be fine.Because I left mine plugged up since the day I got it, and the green and the red lights are malfunctioning.If you leave it plugged up, chances are it could fry.

Yes, you leave it plugged in all the time. I have had the unit for four months and it has been working fine. I have not had a problem with my car battery since I installed it. Hope you have the same results.

It does seem to damage thr battery if you don't use it all the time, if used all the time no problem leaving battery plugged in.

I believe It will not harm the battery if it is left in charger all the time, because when Green Light on the charger is on it stops charging.

Of course... I ever left mine plugged in ever since I purchase the product.. no problem

That's up to you. We leave ours plugged in all the time because that green light is so tiny. But if you want to unplug it just to be extra conscientious, it certainly can't hurt.

You're not supposed to leave it on the charger if it's plugged in. It will lose the battery life sooner. Only charge for four hours when needed.

I don't know the answer to this question. Sorry. I just plug mine in for a few hours and have never been concerned about over-charging it. The first one I had lasted for several years before it finally died--probably from dropping it too much.

I have left mine plugged in for 2 weeks or so and it still works good. I know it says not to charge over 8 hours, but I have and it has always worked for me. I keep it at my 2nd home and don't remember to unplug it from time to time, but, it does still work. Probably not the best for it but....
