UB18-35's anode protection circuit includes the Micro-USB charging port, enabling direct charging using USB cables connected to a 5V adapter, a PC USB port, or any portable power banks. The UB18-35 can also be charged from a compatible Li-ion battery charger. While it is being charged, the indicator lamps on the battery will display the charging status. Incorporating a Japanese NCR18650GA core, UB18-35 features low internal resistance, large capacity, and high discharging current. The core is protected by a three layer system: Pressure Valve, Micropore Partition Plate, and PTC Negative Blocking protection!
There are four protection circuits for: Overheating, Over-charging, Over-discharging, and Short-circuit protection! The anode (positive terminal) of the battery features a protruding cap for improved connection to springs or other PCB surfaces. This improves functionality when the battery is used in series during application. UB18-35 also has an improved exterior wrap to protect the battery from damage and retains the rugged dependability of Weltool!
