Battery Care
DO NOT use any other type of battery charger.
This could lead to damage to the battery
and personal injury.
•
The battery should be recharged as soon as possible after use.
•
This type of battery does not suffer from the memory effect that is widely talked about
and does not need to be fully discharged before charging.
•
Batteries like to be used. A new battery may require several charge/discharge cycles
before it reaches its maximum performance. The same applies to a battery that is only
used occasionally with long periods in storage.
Battery Life
The end of life is defined by the maximum running time falling to 75% of that of a new
battery. For a battery that is used occasionally service life is 2 years.
Replace the battery when running times drop below those indicated or after 2 years.
Battery Storage
This type of battery is best stored partly charged.
A battery that is not in use will slowly discharge. This rate of discharge increases with
temperature. Ideally the storage temperature should be above -20oC and below 20oC. It
must be below 40oC.
After storage in a cold environment allow 24 hours for the battery to reach room temperature
before use.
Fully charge the battery every 2 months.
Battery Test
Test the battery if the running time seems low, a fault is suspected, or to confirm that the
battery is good.
•
Ensure the battery is fully charged.
•
Run the ventilator from the battery until the low battery alarm operates and record the
running time. Look up run time in the table. If the battery is not achieving minimum run
time replace it.
•
If the battery is good, fully recharge it immediately after testing.
Hints and Tips For Reliable Operation
•
Always make sure that the battery is fully charged before use.
•
Do not switch off charger until battery is fully charged.
•
Avoid the temptation to give the battery “a quick boost”. This is of no benefit.
•
If you are in doubt the state of charge, charge for at least 24 hours.
•
If running time suddenly seems considerably shorter than normal, make sure that the
battery is fully charged.
•
Do not charge your battery near sources of ignition.
•
Check the running time of your system regularly.
•
If you have more than one battery, use them in rotation.
•
Do not use if any of the cables or components show any sign of damage.
•
Most reported problems arise from incorrect battery charging.
Disposal of depleted batteries
Depleted batteries may be disposed of in line with local authority regulations.
