Does this battery have an internal chip to prevent overcharging? Thanks in advance

Honestly I don't know, but it's never overheated and always did the job. No complaints at all. You won't be let down, that's a promise

I am sorry to say I never used it because it didn't fit my phone, this is the only thing I don't like about Amazon.com. It is so hard to get in touch with anyone there to get answers about problems. It looks like they would have an phone number to talk to a human and get the job solved. This is the only negative I have ever said about Amazon and I hope it is the last. Amazon is a good company to deal with I just wish it was easier to talk with someone beside a computer.

These batteries have the info chip. You will be able to see the remaining battery life.

You may way want to buy a charge controller to keep the battery from overcharging.

I would suspect it does not have overcharge or float mode to protect from overcharging. There are several out there that are made specifically for maintaining a full charged 12 Volt wet cell battery for around $10 to $15. I use one by Cen-Tech for an old Jeep I have to keep the battery charged.

No it does not, BUT i've had it for about 3-4 years now and have never had a battery over charge. ALSO one key factor when wanting to run a dual battery setup is to start off with 2 new batteries that are the same make and model and pre-charge them before putting them on a vehicle.

Without getting into the technical aspects such as mAh charge capacity, discharge rate, number of cycles, etc. It really comes down to purchasing from a trusted vendor. I if the new battery doesn't hold a charge, it's most likely not a new battery. As for determining if the battery is "Fresh". These batteries are sometimes not charged until you first charge them.

NO. I was able to charge it once and now it won't charge again. I've tried several times and nothing. The computer tells me that it is permanently out of order. Don't buy this battery from here.

You cannot overcharge the battery so don't worry about it. Also no harm done if you undercharge. I have had mine for years, and to be honest do not charge it regularly, and have not had any problems. These are really just guidelines.

Hi, I'm not sure I'm assuming it had to be. I've yet to have any issues thus far! Battery works like original samsung battery as far as I'm concerned.

No, but it in ready the instructions about the battery - simply charging them over night provides a full charge with no worries of overcharging - it is very handy little deal

No it doesn't. I can recommend http://amzn.com/B008OH8BHU as I bought it with this battery and both are working great.

This battery is used in an R61i and I have never checked to see how long a charge will last. I only use this laptop for a hour or two at a time and maybe less than once a week but I am pleased with its performance and you can't beat the price. I even thought about buying a second one as a back-up.

Yes, it has it's own internal battery. As far as a complimentary, back-up battery, No it does not. That would be nice, and a very good selling point.

Yes. The charger is a smart charger. When the battery is fully charged, it goes into a hibernation mode and will maintain the battery, without overcharging it.

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.
