Rechargeable batteries
Read the information below carefully when
using a lithium-ion rechargeable battery
(Li-50B).
4 Discharging
Rechargeable batteries discharge naturally
when not in use. Be sure to charge the
battery before use.
4 Operating temperature
Rechargeable batteries are chemical-based
products. Their performance can vary
even when used within the recommended
operating temperature range. This variation
is normal.
4 Recommended temperature
range
When powering voice recorder: 0 to 42°C
(32 to 107.6°F)
When being charged: 5 to 35°C (41 to 95°F)
During long-term storage: –20 to 30°C
(–4 to 86°F)
Use of a rechargeable battery outside the
temperature ranges above may result in
drops in battery performance or life. When
not using the voice recorder for an extended
period, remove the rechargeable battery
before storage to prevent fluid leakage or
rust.
NOTE
• Due to the nature of a lithium-ion
rechargeable battery, new batteries
and batteries not used for an extended
period (one month or more) may not
charge completely. The battery should
become fully charged after charging
and discharging the battery up to three
times.
