Are these cells protected against overcharge/overdischarge?

I bought these because they ARE overcharge and short circuit protected, unlike the blue ones.

I do not know the answer to your question. All I can say is that I have not had any issues with overcharging or over discharging of these batteries. I have been using this type of batteries (5000mAH) for the last two years.

Generally if the seller doesn't claim that it is "protected", you can be quite sure it is NOT. To protect, they have to add a protector disk, typically at the bottom of the battery; and connect the + & - terminals to the protection circuit. As such the battery will cost more than the same battery without protection. So check the title & description, you should be able to decide if it is protected or not.

Well we plug it in and then come back later and have had no problems so I would say that it won't overcharge, at least that's our experience.

It may overcharge your battery though not likely.It does have a bypass diode which is only useful when connecting multiple panel in series. The diode has nothing to do with overcharge protection.You should consider adding a diode in series with the + lead to prevent leakage at night. Again this will have no effect on overcharge.It may be easier to add a charge controller.

I believe that they are protected. This is a rechargeable, but I haven't needed to use this one yet. It's a back-up battery.

yes you must buy a type of charge controller that prevents your batteries from being over charged or over discharged. a pwm (pulse width modulation) is a good affordable choice for charge controllers. i think the one i bought was 60$

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.

It does have an overcharge safety, but I'd never advise leaving these types of batteries in any charger for more time that it takes to charge them, let alone days or weeks. You're just asking for trouble in that scenario.

I havent noticed any overcharging issues with mine. It indicates when each battery is fully charged.

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.

There doesn't appear to be any protection built into these batteries. I took a voltage measurement while I had these sitting out of circuit and they had just over 4 volts several days after I gave them a little time in the charger.

I don't know. I am very disgusted with them because of low voltage. Below D cells.

I would assume Apple would implement overcharge protection, it should be fine.

There is a cutoff and I believe that the unit automatically dissipates the charge slightly if the batteries are left in the unit beyond the charge up time.The marketing blurb states " Automatically protects against overcharge and short circuit." The only danger I remember is in leaving the unit on with no batteries in it at all.

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

Protected means that the charger is "smart" and will not overcharge your battery. It also will not "short" if you accidentally insert the battery backwards. The charger charges specifically to optimize battery performance

Hi there is a switch inside the battery compartment, if that switch is set to the Nicad position and you put rechargeable cells in the unit they will be recharged with a quite sophisticated charger that does not overcharge or damage the battery. Hans. J Weedon.

Yes. But you have to carefully compare voltage of fully charged cell to depleted one. Best after allowing battery to sit a couple hours.
