What happens if you leave the batteries in the plugged in charger when they are full for longer than 24 hours?

I forgot mine for a couple of days and I have not had any problem with them. They still have the same full charge as before and I use mine in a nebulizer so I'm aware of the time they are used for.

Nothing, the charger has an automatic shut off. They don't even get warm. Well , I should say the charger goes into trickle charge mode. But it will not damage charger batteries.

We leave them on a little while longer without noticing any harm - and nothing in the packaging of any charger I've had suggests you have to get the batteries off immediately. I wouldn't store my batteries there :) But all that happens is the light for the charged battery goes solid and the others continue charging if needed.

I don't leave mine plugged in and I found this on the Apple forum.. "Thanks to an intelligent power management system, the Apple Battery Charger uses less power once your batteries are fully charged, making it one of the most energy-efficient rechargeable battery solutions ever." However, for maximum life, you should not leave the batteries plugged in all the time." It doesn't take long for the batteries to charge fully and if you have an extra set charge them as soon as the "mouse batteries low" shows up on your screen and you should have no lag time.

the instructions say if a battery is left in the charger for more than 20 hours, the charger switches off power to that battery(s). But as others have saidthe best thing to do is remove the battery after the charging is complete.

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.

We leave our batteries on the chargers all the time they are not is use. So far, there have been no significant detrimental effects.

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.

This is a normal behavior with battery extenders and overnight phone connections.. Modern cell phones and lithium batteries don't continuously charge, they stop when they get to 100% and then start again at 97% or so. This means once your phone is fully charged it stops drawing power from the charger, and the charger shuts off. So 30 minutes later when your phone battery is low enough to try to charge again the external power isn't there.

I left mine plugged in for 24 hours then disconnected it and used it. There was plenty of charge left and I won't plug it in again for a recharge until it slows down.

The Charger should utilize a trickle charge feature that essentially reduces the amount of charging once the batteries are "Full". So yes, you can leave the batteries plugged in while in storage as I will be doing the same.

I believe the charger stops when the batteries are full and just maintains them as is. Not sure how long term usage will affect them. However, I have been impresses at how long the rechargeable batteries will last without using them and just sitting in the flashlight. I'm pleased so far with their brightness (like day light to me) and how long they last without recharging. I originally bought the batteries to use with my bike on 25 mile long night rides. It took about two or more batteries for that in order to maintain the brightness I desired.

depends on how discharged your battery is . most of my batteries were charged within 24 hours are less. sounds like you have a battery with a weak cell that will not let the battery come to a full charge '

When it goes completely dead you have to charge it for 24 hours, after that you can put it on the charger every other day.

You should make sure your battery is seated properly - the negative side of the battery should be against the spring. If the battery does not make contact with the charging points, of the charger, it will not charge the battery. If your battery cell is drained then you should allow the battery to charge for at least 4 hours. If you feel the battery or charger is defective contact the seller and they will replace either one of them. This is very rare but it is possible.

In our application we have had batteries in the charger for a year and a half, with no ill effect, so far. We have 3 batteries and rotate them thru the charger. Yes, no problem leaving them in the charger

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.
