GET THE BEST FROM THE BEST
The SF18350 is a Lithium Ion protected SF18350 battery with micro USB charge capability. This allows the user to conveniently charge the battery using any USB power source such as a USB wall charger, computer/laptop, power bank, or automotive USB port. Additionally, an external SF18350 compatible CC-CV cradle charger can be used to charge the battery; possibly at a faster rate if so equipped.
OPERATION
The SF18350 can be used as a standard protected SF18350 in many applications
with one advantage; the battery can be charged directly through the micro USB
port, requiring no external charge cradle. The SF18350 comes with a 6 inch USB
type A plug to micro USB type B plug, with the micro USB plug being the end
inserted into the battery. The battery side includes a micro USB type B
receptacle. Once the cable is plugged into the battery and a power source, the
2 LED indicators display the current charge state: RED for charging and GREEN
for fully charged. The battery can be left connected to the charge source
indefinitely as the internal charge algorithm will restart the charge cycle
once the cell voltage drops below 4-5% of the float voltage. The typical
charge time for charging via the micro USB port for fully depleted battery can
be over 5 hours. The user has an option of charging the battery with an
external charger to shorten the total charge time.
The quiescent drain on the battery from the protection circuit is 40uA, which
in addition to the cell self-discharge, allows a fully charged battery to be
stored for 2-3 years and still maintain usable capacity
SAFETY
The internal protection circuit integrated within the battery assembly provides the following safety features:
- Over-charge
- Over-discharge
- Short Circuit
- Under-voltage
- Over-voltage
ENVIRONMENTAL
Storage Temperature Range: 0-35°C. 60±25% RH
Charging: 0°C-45°C, 65%±25%RH
Discharging: -20°C-+60°C, 65%±25%RH
Note: The battery’s metal button top also functions as a heatsink during
USB charging, which may result in it being very warm to the touch during the
high charge rate period.
