Does this charger have a safety feature to prevent overcharging if I were to leave batteries charging for about 6-8 hours? Thanks!

This charger does have an auto shut off feature that's suppose to shut off the charger to prevent overcharging. I haven't needed that feature, so I can't tell you how well it works, only that's it's available.

I'm not sure if it has this feature, but I usually leave the batteries in overnight to charge without having any noticible effects on performance and such.

Yes. The charger will regulate itself as needed and doesn't over charge the battery. I've had mine for about a year now and have left it connected for months during the winter with no problems. I have several batteries that I switch it around on and can say it's helped all of them. One is about 5 years old and after using this charger on it the CCA's have increased and it's as long lasting and strong and it was when new.

The charger SHOULD turn off or provide a low level trickle charge, so leaving the batteries in the charger should not be a problem. BUT, most of the chargers I have purchased over the years had "fine print" in the directions not to leave the batteries in the charger for more than 24 hours. Why? I don't know, but I make it a practice to remove the batteries after no more than 12 hours.

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.

According to the information I read the built in charger is a float charger meaning it will not overcharge if left plugged in. There is something else offered if you keep it in your vehicle, they will send you mail when it will need a recharge based on when it was last charged. I might add I am very pleased with the performance of this unit.

Yes. While they seem to be somewhat tolerate to overcharging you can ruin them. I've left them for 12hr and had no problem. But when I forgot about one and left it for a day. It was ruined. It just wouldn't hold a long term charge anymore. I had used it quite a bit so it may it was just its time to die but all the others I've had have lasted a very long time.

I never thought about this. I keep my batteries charging all the time. I haven't noticed a problem. Yet, that is. Christine S may have a good suggestion.

The phone's internal charger will allegedly keep it from overcharging and it generally is effective, however it is not smart to do as it tends to allow the battery to overheat and that will shorten the life of the battery eventually. Overnight on the charger every two or three days is best depending on your usage.

Yes, it will regulate itself to not overcharge the battery. However, I would personally consider an unattended charger to be a fire hazard.

Many chargers auto set to these batteries. If you have a charger from years/decades ago that does not automatically switch off I would watch very carefully. You could overcharge and short the battery.

Yes, you can. I've tested the charger while connected to a Watt's Up power analyzer, and once the batteries reach a near-full charge, the amperage the charger pulls in begins to lower. Once the batteries are fully charged, the power analyzer shows 0A of current flowing between the wall adapter and the charging base, meaning the batteries are no longer drawing a charge and thereof are not overcharging. You'll be fine leaving them plugged in, though I wouldn't keep them plugged in for days on end just because you don't need them to trickle charge and lithium batteries have a very slow self-discharge when being stored between uses.

I don't recall reading anything that warns you about overcharging. It plugs into the usb port of your computer and charges rather quickly. I have left it plugged in after it was fully charged and it didn't cause any problem that I am aware of.

No to the first two questions and it depends on the "conditioning" or intent on the purpose of the batteries in answering your last question.Look up the product's manual on line which I did to understand the options on charging batteries to maximize battery life. Please note every option has it own specific time to accomplish its task. The manual will explain. Inaddition, the longer the charger charges, given the task, the batteries-not the charger- will get hot! ALLOW IT TO COMPLETE ITS JOB! You'll be okay.I hope this will help. Good luck!

The instructions are easy... Plug into wall or 12v (lighter) outlet. Batteries will only fit one way into the charger. light will indicate when charge is full. I have not had an issue with leaving them in too long. They will not "over-charge".

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.

It might make the batteries not recharge quite as many times, but I do it all of the time and have had my batteries (Enloop) and the charger for more than a year. I do recommend that the charger be put in "soft charge" mode if you are going to leave the batteries in for more than 4-12 hours.

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.
