The most milliamps I've gotten with UltraFire batteries is around 600mAh. I suspect the cheap charger that comes with these cheap batteries may time out. Panasonics would take a lot longer to charge on that charger than UltraFire batteries. I recommend the ThruNite universal charger 2 or 4 bay with the LCD display that displays voltage. It charges at a 1 Amp rate. I have used it to charge both Panasonics and UltraFires. Best charger as of 8-2014 in my opinion.

I am able to charge with the ultrafire charger, but it takes two - three days. I noticed the voltage creeping up slowly until they max out in the 4.2 volts range and the red blinking light on the charger goes to steady greeen. slow charging at this rate probably wont do the battery any harm.

Use the Nitecore Intellicharger 2or4 bay their the best for just about any battery

For the past 19 months, I've been using the Soshine SC-S2 (Newest version 03 at the time) smart 1A per channel 18650 Li-ion Battery Charger for 18650 Lithium-ion 3.7V Rechargeable Batteries. Purchased from Orbtronic http://www.orbtronic.com/ . I'm sure Orbtronic customer support could help you with specific questions. Good Luck!

They are 18650 Batteries. Amazon has plenty of choices. You will likely need a charger for them also. Decent flashlight - worth the extra dollars for the batteries and charger to round out the set!!

I purchased 3.7V 18650 3000mah Rechargeable Batterys. They seem to work well. I've used them for about a year so far.

Buy the battery and charger. I tried using CR123A batteries and burned the bulb out in one of my flashlights. You can search amazon and find a vendor that will sell you the ultrafire brand li-on 2pack with charger for around 13.00. It's well worth it.

3.7 volt. BRC 18650. 3000 mAh li-ion Ultrafire battery. You will have to buy the charger for the batteries. The ir light takes one battery, but I bought 2 plus a charger. You can also use 2 CR-123, 3 volt batteries for the ir light.

If you are referring to the 1.0 charger DO NOT use it with these batteries. If is is a electrical tape type material, it may be you got the wrong battery. There is a similar model without a case, but a wrapping. They work fine on the 2.0 charger but don't have the circuit which stops them from overcharging, and it is dangerous to overcharge them.

Yes they are. They are closer to the size of a C cell battery but twice as long. They are the same type of cell that is in laptop battery packs. If you search 18650 you will find the batteries and chargers here on Amazon for very good prices. All the Ultrafire batteries I have bought work great. This is by far the best of the best when it comes to budget flashlights like these: http://www.amazon.com/UltraFire-WF-502B-XM-LT6-Flashlight-Clip/dp/B006LVBDNU/ref=sr_1_3?s=hi&ie=UTF8&qid=1364293375&sr=1-3&keywords=ultrafire+502b

Any charger that will fit the 18650 batteries. Amazon has some that are around 6 bucks and I use it. It's generic but works great.

I don't know what to tell you. Without a brand/model of the batteries and charger it's hard to tell. I use an Xtar VP1 charger with LG "HE" batteries with no problem in two of these flashlights. If they are "flat top" batteries they may not be making contact at the top end, "+", of the battery.
