Can i leave it charging over night without harming battery.

I believe the battery charger has an overcharge limit which allows the battery to charge to its fullest no matter how long the battery sits in the charger. I leave my battery in the charger for about two days and have not noticed any problems. Hope this helps.

I left mine charging overnight and it was fine, the battery lasts longer then what I expected.

No. Just make sure that you unplug after a few hours otherwise it could damage the battery

I've used it the entire time of driving however just to be o the safe side I would not leave something plugged in it overnight. Expecially if you have an older 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.

Leaving the battery in after it's charged won't harm the charger but, it can shorten the life of the battery. Batteries need to be cycled between a full charge and discharge for a long life. A few hours won't harm anything but, I wouldn't recommend leaving it on the charger when not in use.

I usually charge it overnight, then turn it the opposite way in the charger until I need to use it. These batteries hold a charge a very long time. Depending on how long I use it on a given day determines if I charge it that day or not. If I use it for just a couple of screws or drill o few holes, then I wont bother charging it that day. If I use it a lot in one day then I will usually charge it overnight and then the next day turn it backwards in the charger. I know it says they won't overcharge but you don't need to put an extra charge cycle on the battery if it's not necessary. I hope this helps.

U don't because it does not have an indicator light. So what u do is leave it around 4 to 5 hrs to make sure u have ample amount of charge.

Hello, I have a habit of charging all devices overnight, so I am not sure if the battery lasts that long

No, the battery cannot be overcharged. But I would not leave it on 'charge' indefinitely.

Be sure you put a 'charge controller' (regulator) between the panel and the battery. If you don't, you will overcharge the battery daytime, and fry the panel at night (because the battery will back up into the panel and fry it).

Yes. You can plug it into an outlet & let it charge. I usually plug it in at night & leave it overnight. Pretty easy.

The device will go into sleep mode but I am not sure if it is a good idea to leave it charging.

You can leave them in without causing any damage since the charging current is stopped once he green light goes out. This is a handy feature for those of us that like to start eneloop pro cells charging on several of these chargers before going to bed. No need to babysit these eneloop batteries or chargers, when you see they're done feel free to take them out, but they can indeed be left in if you're not at home or sleeping when they finish charging.

Typically overnight is adequate. I think leaving on charge for more that 2-3 days shortens battery-use life over time.

This is a smart charger and as such it senses when to charge the battery and when not to with its built in circuitry. So yes, you could leave it hooked up to the battery indefinitely with no damage. Many people do this in the off season when a battery is sitting and not being used. Otherwise, you could be purchasing a new battery if it sits to long and discharges to the point that it can't recharge.

I tend to just leave it all night charging, but I would say maybe 4 or so hours.
