Charging Method - NEC e373 User Manual

1. The e373 is charged by rechargeable charger.
2. Please note that the new battery can reach the best performance after two
or three full charging-discharging cycles.
3. The battery can sustain hundreds of charging-discharging cycles before
out of service. It is the time to replace the battery upon obviously shortened
working time of the battery (session duration and idle time).
4. Please adopt the battery and charger approved by the e373 manufacturer
to ensure the service life of e373; the battery equipped with the e373 is
rechargeable Li-battery. Please do not connect the battery with the charger
for over a week, as over-charge will shorten its service life; the charged
battery will discharge over time when idle for long.
5. Over high or over low temperature will impair the battery charging.
6. Do not use the battery for other purposes.
7. Do not use any damaged charger or battery.
8. Do not short-circuit the battery; the backup battery in pockets or bags may
touch the metal articles (coins, brooches or pens) that may connect the "+"
pole and "-" pole of the battery (i.e. the metal bar on the battery) and lead to
short circuit, which may damage the battery or connections.
9. Keeping the battery in over hot or cold environment will shorten the life
service or reduce the capacity of the battery; keep the battery in
environment between 0°C and 45°C; otherwise the e373 may suspend
operation even fully charged.
10. Do not throw battery into fire.
11. Please dispose of the battery as required (recycled), do not dispose of
battery as living rubbish.
12. When not using the battery for a long period, remove it from the e373 and
store in a place with low humidity and low temperature.

The e373 is equipped with the rechargeable Li-battery; please adopt original-manufacturer
charger and battery to ensure the e373 service life.
