Battery Care
The Flite 2 pump utilises sealed, valve regulated, lead/acid batteries. This type of battery requires no
maintenance and when used in accordance with manufacturer’s instructions should give a life of approximately
400 charge/discharge cycles (based on 50% depth of discharge). Battery life is affected by a number of
factors, but the most significant of these are overcharging and the depth of discharge in use.
Overcharging of the battery causes overheating and off-gassing of the battery electrolyte which will lead to
loss of capacity and reduced service life. The Flite 2 charger (part no. 901-210) is an intelligent charger which
automatically detects when the battery is fully charged and switches to a trickle charging rate to prevent
overcharging. Always use the correct charger.
A deeper discharge of the battery prior to charging will result in a shorter battery life. This can be as low as
200 charge/discharge cycles if the battery is fully discharged every time prior to charging. If the intended pump
usage pattern would fully discharge a P901201 3.2Ah battery between charges, it may be advisable to select
the larger P901202 7Ah battery, which for the same usage pattern could have a life of up to 500 charge/
discharge cycles.
Long term storage - If the pump is to remain unused for a long period of time, SKC recommends that the
battery be fully charged prior to storage, and a top up charge be carried out at 6 monthly intervals, or if stored
at a temperature in excess of 30°C, at 3 monthly intervals. Failure to do so could lead to significant reduction in
battery capacity and service life, and in extreme cases can prevent the battery from accepting a charge entirely.
Note that the pump should either be put into ‘Sleep’ mode during long term storage, or ideally the battery
wires disconnected from the battery terminals (these would need to be reconnected during top up charging).
Battery Disposal - The EC Battery Directive requires that all lead/acid batteries are disposed of correctly at
the end of their working life. This means that they must be collected and treated separately from other waste
to ensure that the harmful lead they contain does not enter the environment via landfill sites. Please ensure that
any end-of-life SKC batteries are collected and treated correctly.
