2.2.5 Usage Tips
The battery is losing storage capacity as you go through its life. Contact your
PROMAX distributor when necessary to replace the battery.
To prolong battery life the user should follow these tips:
In case of providing a long inactivity period of the equipment it is
advisable to make every 3 months a charge / discharge cycle and a
subsequent partial charge (40% aprox.).
It is advisable to keep it in a cool place and away from heat.
You should avoid keeping the battery for a long period of time at full load
or fully discharged.
There is not necessary to wait to fully discharge before a charge because
these batteries have no memory effect.
