Batteries
The
Stairmax
is powered by two 6 Volt batteries which are maintenance-free and
rechargeable. The batteries capacity allow to drive about 650 steps upstairs or for
approximately 30 minutes when fully loaded. The charge state of the batteries is shown by
indicator lamps located on the
Stairmax
drive which have to be checked before each
operation. The recharge time varies according to the battery status but should not exceed
the maximum of 8 hours.
The battery charger uses your AC power to reload the batteries. A 12 Volt charger is
supplied with the batteries. An overloading of the batteries is not possible as the charger
switches off when fully loaded. For more information please check the user manual of the
charger.
Attention:
The use of a non-adequate charger can damage the batteries. If an alternative
charger is used please check if its
compatible and don’t use an acid battery charger.
Use of the charger
1.

Stairmax

2.
Connect the recharge cable with the battery box.

Connect the charger to a 220 V power socket.
4.

charger switches off.
Prolonging the battery life-time
The life-time of the battery can be prolonged by on-time recharging. If the battery is totally
empty the recharge cycle can only be repeated approximately 180 times before the battery
get unusable. But if the battery is reloaded when not totally empty the cycle can be
repeated around 1200 times thus increasing the lifetime by the factor of 6.
If the battery is stored for a long time without being used it can be reactivated by using a
stronger charger (shock-recharge) for a brief time and then using the normal charger to
complete the recharge. In this case it is advisable to consult a expert company.
Please make sure that the emergency stop button is not switched because then there no
power connection is given.
