Battery life says they are good for 500 cycles. Are you better off running them down or re-charging them every day after 2-3 hours of use?

Battery charge lasts about 5 to 6 hours. I bought 2 of them and just change to the spare it I am watching that long!I don't worry about the battery life for the price :)

Normally it is best to recharge when it is needed which means let it run down as ea h "cycle " is normally counted as a discharge/recharge...but not sure. Hopefully factory answers

Less than 4 hours for mine. The battery really does last a long time. I've had mine for several months and use them for up to 4 hours or more at a time, a couple of days a week. I have only had to charge them a couple of times so far. I am impressed with the battery in these.

I have never completely drained the battery in 1 use . I usually charge them up at night whether the battery is low or not . I would say you can get at least a good 4 hours out of them , beyond that ,I can't really give you an honest answer. We haven't had them long enough To experiment . Between my 2 kids and I ,we have no complaints and we each have a pair they are not the best headphones you will ever own , but they are incredible for the price and sound quality.I think it may also depend on what your expectations are , we use them to listen to music and watch movies .

I just plug the batteries in for around 8 hours and use em. It works well for me. I hope this helps. I had also purchased new batteries and I charged them overnight the first time. GOOD LUCK

You will need to charge it every day. I put mine on around 12am when I get in bed and I'm not sure when the battery dies, I'm asleep when it happens but with heavy use you will need to charge more frequently I plug them in every time I use them and they're always ready to go when I am, they charge fairly quickly IMO

Battery life depends on usage and battery condition, as batteries are a consumable item with limited lifespan and performance will gradually decrease over time. That said, I would expect a battery in good condition to last 3+ hours under light to moderate use.

We usually don't use ours for more than 90 minutes of continuous use. They could probably hit 2 1/2 hours with a decent battery, but it might be a stretch. I don't know if you need them to run continuously for the whole time, but we try to conserve power by turning them off when not actively in use. We're running them on Energizer rechargables.

Hey Chuck, I bought these batteries about two months ago and they are awesome. I have a two year old EVO 4G and I still like it better then any other phone. The old batteries died and I almost traded in the phone. First I got cheap $2.00 batteries that claimed they were long lasting. The were bad and stopped working well within a couple days. Then I decided to get these batteries. My phones charge can last up to 3 days now. I have nothing to gain from this response, only good Karma if the batteries you get work as good as mine.

We used these on our 9 day trip in New Zealand and found the battery would last all day, which was often at least 8 hours of usage. We didn't need to use them beyond that. I.e. battery life was never a problem for us.

you can charge them as much as you want they don't acquire a 'memory' but as soon as the fully charged light comes on remove from charger they can be damaged by being left on charge they don't seem to discharge just lying around the mah hours on these batteries are greatly overstated

Depends on the brand of batteries but I was energizer max and using it everyday they last a month or two

I charge mine over night and then use till it starts to slow down then over night again. I have forgotten about them in the charger for about three days, they were hot, and over the years it seems to shorten the life of the battery. so 8 or 10 hours for full charge.

Basically I got very sparse directionsMyself. These type batteries should not be charged over 8 hours. Will possibly overheat. Recharge when they go dim. I never need to use full power as housing gets very hot. Do not leave light connected to battery as small led in switch will run down battery. Hope this helped. Lee R

Not sure how you plan on using them, but you need to know your wattage needs. these battery's are rated 3.7V 5000mAh (5 amps for 1 hour) So 2.5 Amp for 2 hours, 1.25 Amps for 4 Hours, etc...

No problem to leave on charge a day or so, but overnight is MORE than sufficient. I would not purposely leave on charge for more than 8 hours, but doing so every once in awhile is fine. I purchased additional batteries, BUT I bought those with even more power for better life.

My battery life's pretty good, if I use it a lot it lasts about a day and a half, usually I don't use it that much so I end up charging about once every two and a half days.

I have used them for 6.5 hours so far today on one charge. The battery is still going.
