Ultrafire 18650 Protected Rechargeable Lithium Battery
Detailed Description:
Protected 18650 2400 mAh rechargeable 3.6 volt battery - charge with the Ultrafire Multi-Battery charger.
The advantage of this cell is that it features a button top making it particularly compatible with many flashlight applications.
Rechargeable Lithium batteries are rapidly becoming a very economical way to lower the operating costs of Lithium-Powered flashlights. We offer a number of different options in order to meet any rechargeable needs. These are Protected batteries.
These fully protected cells simplify usage with their integrated PCB. Perfect for your single cell application these cells are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell. If you are building a pack please choose one of our other cells and the appropriate PCB.
Features and Benefits:
Unique and New! With integrated PCB Protection!
Lithium Ion 18650 cylindrical rechargeable batteries
Internal PCB protection prevents under-voltage at 2.5V and over-voltage at 4.25V.

Li-Ion Charger
Features and Benefits:
Universal Li-Ion battery charger for 18650, 16340 (CR123A sized), 17670 3.7V Li-Ion cells.
Can be used anywhere worldwide with 100-240 V input. Good for oversea travel.
Smart charger automatic cut-off.
Product Specifications:
Power Input: AC110~240V, 50/60Hz
Power Output: DC5.5V-350mA
Charging time:
800mAh: 3 hours
2000mAh: 8.5 hours
2200mAh: 9.5 hours
Dimension: 3 13/16" x 2 3/8" x 1 5/16"
Weight: 3.9oz charger and adaptor together
Instructions for Use:
Insert cell(s) into the charger before connecting charger to power.
Plug in Charger.
If batteries are removed during charge, unplug charger and re-insert batteries.
LED light for charging status indication:
When charger is plugged in and received power the LED strobes Red/Green.
LED is Red when charging, Green when charging is completed.
If LED is off or flashing at an extremely fast rate, the cell/s are not suitable for charging with unit and should be removed immediately. If cells are installed with polarity reversed, LED will also be off - simply reverse polarity of cell.
NOTE: The power output of this charger is incorrect for the protected 3V 750 & 900mah RCR123A cells that we carry. We specifically do not recommend using this charger for those cells. Only use this charger with 3.6 & 3.7V cells.
