It regulates the voltage and amps from the charger in relation to internal parameters. This keeps it from overcharging and bursting, or catching fire.

That's my experience, but I haven't seen that in the instructions. I've been using rechargeables for 20 years - when ni-cad was the latest tech. I'm disappointed in the large number of cells that fail after only a few recharge cycles.

This two cell battery pack has a total rated output of 1000mAH. Don't go by the picture, go by the printed specs. I have had this battery pack installed in my old Norelco razor for well over a year now and it functions perfectly. I have used many other Tenergy rechargeable battery product for well over 15 years and have never encountered any problems whatsoever. Very high quality products at very reasonable prices!

It defines it as such on the face of the battery. I would recommend a Sony InfoLithium battery.

It is hidden in the description - 18650 Battery. Search Amazon or eBay and you'll find them. They are a slightly wacky but very effective Li ion battery. Do some research and get a reasonable quality. Some of them claim high storage but I think they are all about the same.

Probably the difference is in the tabs. These two urls give you some info on the tab configurations and the significance of the letters. http://www.standardbatteryinc.com/blogs/batteries-101/11639085-battery-terminals http://www.standardbatteryinc.com/blogs/batteries-101/11786397-the-ub12180-battery The main difference is probably the terminal configuration. Did you specify a tab style?

'Non-spillable' is printed on the outside of the battery. It's a sealed type.

Older batteries used to be susceptible to "memory" meaning if you kept charging it when it was only 1/2 discharged it would eventually think it was dead at 1/2 full. Memory free means you can charge it whenever you feel like it without worrying about the memory thing.

Its an older style, may need an adapter to plug into some of their batt packs. But it has 7w more power gen. The adapter is on their web site but hard to find. I like mine!

Hey there =), Neither, the 18650 3.7V is its own type battery. It is used for certain devices and i use them to power my Cree Flashlight.

The description on the back of my battery rates it as 7.4V 2200mAh. Li-On isn't mentioned -- assume it stands for lithium ion, which these are. Work great in my Core micr+wire gloves, now going on four years! Got new batteries a few months ago. Caveat: I can't get more than 2 hours out of batts without recharging, and usually a little less. I keep a second pair charged for longer periods. And, recharging fully usually takes about 4+ hours. Still the best thing I've found for my colder-than-normal hands during Colorado foothill and mountain days below about 30F. The gloves are even better fitting, more flexible, and sleeker than most outdoor activity gloves. The description on the back of my battery rates it as 7.4V 2200mAh.

I assume you're talking about the barrel connector on the plug and its mate in the battery? The outside is return (negative) and the inside/recessed pin is power (positive). That is for safety reasons, so that if the barrel connector touches something grounded it doesn't short.

I have a old battery pack that would not take a charge. it has 18650 F 22 cells (X6) Google 18650 F 22 it shows Li ion cells . . they are 3 volts the voltage protection card limits discharge to 8.4 volts so it doesn't damage the bulb. you are asking me to remember my electronics from 1967 so I am a little rusty but you wind up with three batteries in series X 2 and you parallel the each 3 cell battery to get 6000 ma

I am not sure. I am not at home at the moment, but I think that it means that the battery is fully charged and is now working as a maintenance charger. Just keeping the battery at full strength.

I'm not sure. It is a sealed battery, like the ones you would find in back-up emergency lighting.
