Hiow long will the the 4000mAh hold a charge if in storage? glove comparment etc.?

I beleive the storage is up to 90 days (or up to a year with reduces charge) , however, please note, it is best to store these in a safe indoor environment, as extreme heat or Cold can damage, and or reduce battery life span and capacity. Thank you, BuysPro

mine lasted over 90 days after a full charge, was only half charged but not completely drained, i kepted in a zipped platic sandwitch bag to make sure itdid not made contact with all the other items in my glove box i.e. emergency flashlight etc,...

It's been good so far... But give me until the 26 that's I'll be coming back from a trip that I'll definitely use that battery a lot.

i have never tested the last time of the full charge. i do know that it will perform after 12 hours of medium use.

what matters is the voltage and that it fits . the 4400mAh and the 6 or 8 cells is just how much charge it holds. the important thing is the voltage must be the same.

Too early for me to give you a statistically accurate assessment. However, if you are going to store this battery for some time I would bring the charge down to about 40 percent charge and then store it (non usage).

I have not conducted a careful measurement, but the two I purchased hold a charge for a similarly long time and have remained useful since I purchased them. If forced, I would say that they seem to hold a charge nearly as long, but not quite as long as the original. I use them as a back-up when I might be far from any way to recharge the battery. When I can bring the charger along and use it, one spare would be ample.

I find that at full charge the batteries last more than 4 hours. I think it is a great idea to keep a spare charged. Especially if you are editing or taking video as well.

Never had a problem with batt life, longest usage about 4-5 hrs but i charge it after that with left over current in it.

I usually charge it about 4 hours and the battery will be hot to the touch. It should be good to go

You would have to contact the manufacturer of the gloves. I found that because of the circuitry in the batteries themselves its not probable that one battery even with similar specs with another battery of the glove manufacturer will work. I tried to use the batteries with similar specs on my Venture vest but they wouldn't work. I also found that although I had two old batteries that now wouldn't hold a decent charge because they had been dormant too long I could continually charge them up, use them, and eventually the charge times would be back to what you could expect from new batteries. If you can keep them charged up they will last forever. You would have to contact the manufacturer of the gloves.

It lasts a moderate period of time. Sorry, don't have the exact. I ordered a new cable with it and the box attached gets very hot. The most annoying thing is that this battery falls out...It doesnt fit like the original, it's dimensions must be a millimeter off...

It would be safe to say 8 hours, but it lasts a long time. There is no worry in the battery department!

With my experience with these batteries, it normally takes around 5 hours, if memory serves me correctly

Well in the first place, I doubt you will find a true 4000mAh 18650. Panasonic has a 3400mAh and that is the highest true 18650. Anyway to answer your question the battery will be heavier then a 3000mAh. However, some 18650 have a PCB for overheating, these batteries will be longer. FYI; UltraFire does not make an 18650 over 3000mAh. These batteries pictured here are counterfeit and Amazon know it. Do not buy. A true UltraFire 18650 battery weighs 1.5 ounce (42.5242847 Grams). The Cathode plate (negative end) is brass in color and has their trademark stamped on this brass colored plate. This trademark stamp states Ultrafire (not UltraFire) with two fire flames located directly above the "e". The Maximum mAh (milliamp hour) is 3000. Any UltraFire 18650 battery stating that it is over 3000mAh is a counterfeit. Any UltraFire 18650 that does not have the above description is a counterfeit. The range's of the UltraFire 18650 batteries are 3000mAh, 2600mAh, 2400mAh and 1200mAh, http://www.ultrafire.net/shownews.asp?id=60 http://www.ultrafire-shop.net/page3.php http://www.ultrafire-*shop.net/data/storage/attachments/94a73d230e2445b0feea1ef30f550de0.jpg *The above web site is a CR123A not an 18650 but this is how the Cathode appears on the 18650. By the way, I am in no way affiliated, connected to or know anyone affiliated or connected with UltraFire. I am a consumer that is getting tired of being ripped off, lied to and cheated. So I decided to do some research and this is what I found.

From my experience with Trustfire and other *fire batteries in the past, you can usually halve the mah claims, so these would probably be much closer to 2500mah than 5000mah, so I would guess that Orbtronic 3400s would last longer. Neither Orbtronic nor Panasonic inflate their mah, assuming you get authentic ones.

5 to 6 hours which is not bad considering, another back up battery its very helpful for a maximum user. I love it . and plus if you plan to go that route for a spare battery you van also have that chargin, while you connect your USB charger to just charge it from your pone as well come with a built in USB charging port.

I'm not sure what you might find to be the difference. However, I do know that my 4400 mAh still lasts me over 5 hours of intense use, and I've been using it daily for almost nine months I believe. Either way I don't think you can go wrong!

Mine has 5010mAh at full charge. It's sufficient for 1.5 to 2 hours of hard use. That works for me. If you need more you might want to spend more, but considering the price, i'm satisfied.
