Can you damage the battery by over charging or leaving it on the charger to long?

I've left mine charging for several days, and have never had performance issues with the battery. I know that's purely anecdotal, but its not something I've ever had an issue with.

I have left mine on overnight many times. No problem. My lights have lasted 12 to 18 months of hard use. We do undercar work and use them all day long. We charge them when they get weak. This us usually once or twice a week.

Hi Carlos - after I installed new battery, I left it to charge but looked at it about 15 minutes later and the window was charged up when it had been at zero before I put in battery. I don't think you can ruin battery if your phone is charged and you use it, and you can't go wrong with the price. It's been working like a dream.

I have never removed this battery since I bought it and it has received several charges. i try not to leave it on the charger since I have heard, cell batteries in general, do not do well when left on the charger at a full charge.No specific issues with this specific battery however.

You can leave it in as long as needed. The light will change color when the battery is fully charged. However, once it is fully charged, it should be removed because overcharging can damage the battery and shorten its life.

Lordy no. I plug in the charger with battery in , out , half in. Pull them out early. Short charge etc. overload and over discharge, it handles it fine. My battery life is shorter than some but it's a tool.

I don't think you can overcharge the battery with the charger. It has an automatic They last a bit longer than the original one. But not much of the difference.

No. This charger will continuously charge so after no more than 24 hrs. You will want to unplug the charger to prevent over charging. Hope this helps.

Hi Emerson, No, I haven't had that happen to me yet and I left it on there for 2 days. I forget it's on there. So, In my opinion, It will not overcharge the battery.

Yes it can but if you leave it on rge charger all the time you can damage the battery. Better to just charge when needed.

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.

yes it will not overcharge, once it drops below full charge it brings it back up. I have three of these and always leave them in with no problems

This is not official, since there is no doucmentaion on this subject, but the way i do it, is pull it out, when the battery charger stops its animation (empty, 1/4, 1/2, 3/4, full and repeat) Damn i wish there was more documentation that came with this player. It could've been great. And yes, i already overcharged mine, it only last now for about 4 hours after a day of charging.

I don't think any harm was done I have done the same thing and not seen any change in the life of my battery. Also the charger takes a bit of time to fire up as you hear it winding up to full speed and I have just pull one off and stick another on nothing much has changed for me so far. Hope this helps guys.

Considering this charger has a test/refresh feature, leaving the batteries on the charger will not damage them even though they are being trickle charged. Though i usually will not leave batteries on a charger for much longer than when it says it's full due to the possibility that they could weaken the batteries causing you to leave the batteries in refresh mode which takes up to 20 cycles depending on how bad the memory effect is on the batteries.If you buy the staycharged batteries that don't lose charge within a year there is absolutely no need to leave them in the charger, but if you got older batteries leaving them on will keep them charged whenever you need them.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry. I cannot answer that question.

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.
