Zartek ZA-711 User Manual - page 9
CHARGE TIME is approximately 5 hours from flat to full.
OPERATING TIME is approximately 17 hours on 1W power setting or 10
Hours on 5W power with a fully charged battery if used typically on a
5:5:90 duty cycle.
Note:
1. Make sure the radio is switched off during charging or the charging time
will be longer.
2. Li-ion batteries do not have memory so they can be recharged at any
time. There are a limited number of charge cycles that the battery can
handle, typically 500-700 times. To get the maximum use of the battery,
only recharge when getting flat. If an almost full battery is recharged,
the charging cycles are not optimized.
3. When the battery charge goes flat, the radio’s LED will flash a red light
and the radio will keep reporting “Please charge the battery”.
