what is the battery life? how long does one full charge last?

I have watched 4 full length movies before I charged my glasses. The batteries still had a charge, but I didn't want to take a chance. I'm new to the 3D home theater world. I probably could have gotten another 4 or 5 movies out of the battery on one charge.

Ridiculously long. I rarely use them and weeks to months later they're still registering as fully charged off the initial charge. My Epson glasses that came with the projector lose their charge very quickly in comparison when sitting around unused. I've never really tested it, I just do a recharge every few months if I think I'm going to need several of them.

Mine runs a minimum of 30 minutes on a full charge. I've never run it out so I'm not sure how long it might last.

I use it at school. Fully charged, it can last me 5-6 hours or so, depending on if I shut it down, or just let it sleep

while operating - at least 6 hours. I think mine died during the 7-8 hours after a full charge. I leave it in my car and the batteries remain charged until I actually use it and I'd say it keeps its charge for awhile, on a monthly basis. Not too sure about annually.

I have used it a couple of times, the battery lasted about 6 hours the first time, once I charged it fully it lasted about 12 hours and I haven't charged yet since. hope that helps.

Clarence is right, one full charge of the lithium batteries will last 15-20 hours of continuous use. Charge it over night and it will last all day.

I have never drained a full battery in any one use. I have taken my dog out using this device for 2 hours and the battery is still going strong. Sorry I don't know the exact answer, but hope this helps.

How long did it take you to charge this up to full capacity upon receiving?

Battery life is pretty good... A whole day if your actually using it.. I've left it sitting and it's lasted around 3 weeks without usage on one charge.

The initial charge is 6-8 hours. how long mine took after that they charge full with in 1-2 hours lasts me like 3/4 of the day

one charge last me 3 days. the recharge is about an hour but you can recharge and listen to music at the same time.

I would say the battery life depends on the display settings. With full illumination, I think it's about 6 hours.

Probably an hour for a full charge. I finally had to replace my battery because it would not hold a charge. Pull yours out and see if it is bulged in the middle. If so it is bad.

Hello. Based on usage a full charge should last between a couple weeks of non-usage to a few days of extensive use. Thank you

It takes only about an hour to fully charge if that. When using bluetooth I get more than 10 hours. With the cable, I get between 15 and 20 hours of listen time. The battery life is stellar.

Actually, my first full charge took almost 48 hours. I initially thought the battery was defective. However, every charge after the first one has been relatively "normal" (4 hours or so for a fully depleted battery). I'm very pleased with the battery's performance. It lasts for slightly over 48 hours with GPS, Wi-FI, and Bluetooth turned on; and normal call/text/surfing use.
