Battery for emergency lowering
An emergency lowering battery can be fitted onto 4-sectioned beds.
A LED lamp on the battery indicates that charging can take place.
Please be aware that the emergency lowering battery can only be attached to the leg motor on 4-sectioned beds.
Preventive battery maintenance
The accumulator has to be exchanged after 4 years. Depending on how the battery is used, the exchange may have to
take place earlier. Frequent, sudden discharges reduces the battery’s life.
We recommend that the accumulator is tested at least once a year. The accumulator is not damaged by continuous
connection to the mains.
Exchanging the battery
The accumulator must be exchanged with an accumulator of the same type or a mechanically and electrically
compatible accumulator (12V – 1,3Ah). The accumulators must be new or charged at least every 6 months for
maintenance purposes.
Warning! Old or faulty accumulators may generate an explosive gas mixture during charging.
The accumulator box is provided with vents to ensure adequate ventilation of the box.
The vents must not be blocked or covered, as this may result in pressure build-up
and the risk of explosion.
Waste disposal
Old accumulators may be returned to Invacare®, alternatively they are disposed of like car batteries.
