Rechargable batteries: Does anyone know how many charges these glasses can take before they will stop holding a charge.

Well... I can't say how many charges they'll take, but the first two charges of mine have lasted over 20 hours (I think the first charge was around 30 actually) so I don't think you'll have to worry about them dying on you anytime soon... at least I hope not. If you're really worried, just go and get the older glasses that use watch/button batteries... that's the safest bet, I guess.

Since they are rechargeable, I have no idea how many times you can charge them. However, we've never had them discharge fully but only use them a maximum of 3-4 hours at a time with no problems.

rechargeable batteries come in different strengths which determine how long they can hold a charge and how many times they can be recharged.2500 seems to be about the strongest and they go all the way down to 600. try getting some 2300-2500 and see if they last longer. the number is listed on the side of the battery and somewhere on the package label but in very small letters. 4 AA batteries of 2300 mamp rating are under $10 at Walmart.

These batteries will hold a charge, we cannot guarantee a new or fully working battery. Since these units are refurbished. We do not warranty the batteries.

I'd use LSD rechargeables for sure, since they'll keep their charge. But I would recommend Sanyo Eneloops over these Tenergy batteries, I have had much better luck with them.

I have had no problem with mine they still work or recharge well and hold a charge when not in use. I really haven't recharged them enough to know how long "Normal" would be.

4 AA. Rechargeable batteries work just fine. Honestly, for a flash I would recommend them. I use Sanyo Eneloops and they last quite a while between charges.

Mine holds up to 4 aa or aaa batteries. Must charge a minimum of 2 at a time.

Oddly, these batteries remain on the list (as of Aug 1 2015) even after I've put a check in the "rechargeable" filter (to stop seeing non-rechargeables). They show up as "rechargeable" even though (based on the answers here) they almost certainly aren't rechargeable.

These are facile batteries and charging is difficult to pin down. The first time I charged them it was maybe about and hour, but they were not completely drained either.They should not be over charged are over used in my experience. They get really warm in the torches and will at this point discharge rather fast. I try and watch them when charging because I really don't trust them, when the Green light comes on I take them off the charger quickly, hope this helps.. PS: this is the first time I have had all eight being in perfect working order since I started using them.

I am presently out of town and unable to look at the ones I have. I have never had a problem. They are always well charged and quite btrght when darkness falls. I will be home the end of the first week in Feb and would be happy to check and see if the batteries are replaceable. Off hand I think they may not be, I recall they are well sealed.

I have only had mine for a few months, ive had no issues with them holding a charge. When we were out of power for three days this summer, it was on and working all night and charged all day with regular daylight and was ready to go for the next evening. I just bought four more so we will have enough for the house.

I've never tried rechargeable batteries, but a regular battery. The power consumption of this device is really low so one pair of batteries lasts forever.

The glasses I purchased are not rechargeable. You need to replace the battery located in the center of the nose piece.

I would do one of two things. Charge them for 24 hours. Or send them back. Mine only lasted about 3 charges. That still put them roughly the price of a good disposable battery, but these are not high quality.

I haven't counted. I use many of these & have them in a pile. I'd say it's totally worth it to buy rechargeables. I have a little battery tester device that I use to keep track of which ones that are charged. I have some in my rotation that are a couple years old.

I use rechargeable AA batteries. ..I picked up whatever was cheap at the local store.They work just fine...if you keep four in the camera and four charging, you'll never run out!
