Will this battery be harmed if it's left in the charger even after a full charge is reached?

If it were going to be a long time then yes, but to leave it there during the week and just use it on weekends is fine. I do that often

There should be no harm, I have had no issues with leaving it on the charger after reaching 100% and have not heard of any problems. That said, I have but don't normally leave it on the charger for extended periods out of habit, not concern for the batteries condition.

I think the battery goes to a disconnected storage state rather than being maintained. More like you put it on a shelf after a full charge. It will slowly leak down

The batteries charge up pretty quickly. I have never left it on the charger for more than an hour so I couldn't tell you if it would harm it or not. You might want to contact Ryobi to check for sure.

I have a couple batteries that don't hold a charge long so I leave them in the charger and they usually get the job done before they lose the charge again. I always keep one in the charger.

I think that is probably the reason my battery failed. I don't know how long is too long.

Sadly, I'm not able to answer that question adequately at this time. I haven't had mine long enough to know. As a habit, I do remove the battery once I'm done with it. But I use mine until all charge is down and then have a full charge ready to go for the next time and "that" charge appears to hold when I use it.

No, there is over-charge protection built into the battery. With that being said, I still remove my batteries when I see the charge is complete. The 18 month warranty doesn't hurt either :-)

As I understand from the instructions, you can leave the battery in the charger. It will not overcharge.

I think so. I have left mine in the charger for several hours past full charge with no ill effects, but usually I remove the battery when the light turns green.

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.

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

I've owned mine for almost a month and use it every week. I always leave 1 of my 2 batteries in the charger between uses so that I always have a fully charged battery. The instruction manual says that's fine and so far, I have not seen any issues with doing so.

Yes it may have some level of charge, I would let it discharge completely and then fully charge it. Better safe then sorry. Some batteries develop a "Memory" charge and they do not retain a full long life memory. Please "Goggle" the term memory charge regarding batteries for a complete understanding.

I don't usually let the battery below 20%. One thing I have learned is that some chargers will burn out a battery if left plugged in continuously. Unplug when charged.

It has been my experience that it is best to disconnect the battery once it is fully charged. I don't think it will be unsafe, just not good for the batteries.

It's depends on the charger, not the battery. And, for this battery, never let it die, or it will die forever.
2243842
Yes, just like any other charger but you can leave it hooked up after charging is completed. If the dead battery is no good, nothing will help.

No. Its life is relatively short. Hint. Don't leave it on the charger overly long. And run it pretty nearly down, then recharge it.

I would say NO!!! Could damage charger and possable damage to yourself. Contact Black and Decker for help.

I honestly suggest that you should not leave it there overnight so it will not over charge the battery itself. thanks

I know if you leave it plugged in all the time it can end up ruining the battery. But if that is not the case then I would contact the manufacturer.
