They last as long as they should before recharging. I have only had them a few months, so I don't know how long I will need to replace them At the price I pay, I really hope they last at least 5 years.

These are just as good as the original GoPro batteries and seem to last just as long if not a little longer.  I've been using these for about 2 months now with no problems to date.

Buy these all the time. Never had a problem
 Last about a month per battery.

it seems to me that reviews and my experience suggest that to prolong the life of these batteries one should keep them on the recharger only as long as it takes for them to be fully recharged... leaving on overnight, or longer than the full charge is reached, is unnecessary and probably harmful...

With me these cords seem to last about 6 months apiece but so did the original. They work for me in every situation, always charges, always syncs. For the price I buy them 2 at a time so I'm never without one.

I've been using these for a few months and have been happy with them. They hold a charge well, and I have no problems with them in my camera.

The battery lasts as long as described and saves you the hassle of buying batteries. They charge fairly quickly as well. I'm just wondering how long they'll last until they start to loose their charge capacity.

These batteries last a LONG TIME (several hours) in my R/C car.  They take a while to recharge (several hours), but it is worth not having them die quickly.

These batteries seem to last quite a while once charged. But for myself, I would make sure they are just about dead , before re-charging again, this will give you more life to your batteries.

After replacing the batteries in my Uniden phone with these and fully charging them for a few days I kept the phone off the cradle to see how long the batteries would last with normal usage. They last a week or more before needing a recharge. My old batteries would barely last a day. These batteries are the ones to get and look and act just like the batteries that came with my Uniden phone.

So far so good.  I have had to recharge them once so far and they worked flawlessly.  Thinking about buying more.

These are the same batteries I purchased when I bought my camera. They only last about two years but that was with continuous use. I can't imagine how many throw - aways I would have used by now. I use the dock that came with my camera to charge them. I have two batteries so I always have at least one charged and ready to go. Very convienient.

I added these batteries to my collection of 40 or more rechargeables that I use in my portable electronic gadgets.  No problems with any of them so far.  One benefit of rechargeables, when they get low, simply take them out and recharge them.  I don't need to carry extra batteries and wait for the ones I amusing to become unserviceable.

These batteries seem to last as long as OEM, although I haven't used them long. Nice to have a cig lighter for charging as well if you do stuff away from AC power.

I've been buying these for years...so long, I don't even remember.  They last quite a while before you feel like you have to replace.

Five star...batteries hold a charge for a long time.  Through the old one away(recycle).

I'd give it more stars if they actually lasted 8 hours like they state they will. I fully charged them prior to using them but I'm lucky to get 4-5 hours of listening to my music before they need to be recharged. Other then that, they feel comfortable and sound great.
