Battery Life
The high quality battery used in the Powerpack Solar 400
will serve as a reliable power source for years when properly
maintained.
To maximize battery life, it is important to recharge the
Powerpack Solar 400 battery after each use.
Recycling
The Powerpack Solar 400 is designed to provide years of
service. However, when the internal battery reaches the end
of its service life, the Powerpack Solar 400 itself is no longer
useful. The internal battery is not designed to be user
replaceable.
Because the internal battery contains lead, which can be
hazardous to the environment, the Powerpack Solar 400
should be recycled or safely disposed of at your local
recycling depot.
CAUTION
Due to inherent self-discharge, lead acid batteries must be charged
at least every 3 months (once a month is recommended), especially
in a warm environment. Leaving a battery in a discharged state, or
not recharging regularly, may result in permanent battery damage.
Damage to the battery caused by neglect is not covered by the
product warranty.
Important: Recharge the Powerpack Solar 400 fully at least
every three months (once a month is recommended) if it is placed
in storage or in a vehicle trunk. Store in a location that maintains a
temperature range between 32 and 86 °F (0 and 30 °C).
CAUTION
Discharging the internal battery below 10.0 V will damage the
battery and shorten its life.
