Check And Repair Work; On Electrical System; Checking Batteries, Battery Boxes And Battery Potential - Invacare STORM Service Manual

12.0 Check and Repair Work on the Power Supply
12.1 Testing Batteries, Battery Boxes and Battery Voltage

NOTE
• Make sure that both batteries are charged.
If the total voltage is below 24 V, charge batteries
completely (see chapter 12.2).
• If the battery voltage drops below 21 V during operation,
the driving speed will be reduced step by step to minimize
power consumption. If the voltage drops below 17 V, the
power supply will be cut off entirely.
• The voltage of each individual battery should not be less
than 9.5 V.
• A voltage drop can be checked during driving operation
with turned-on lighting and activated hand brake.
CAUTION:
• Handle tools carefully. Do not bridge the battery poles.
• Take into account the weight of the batteries of approx.
22 kg.

NOTE:
Exact information on the condition of the batteries can be obtained by a

CAUTION:
For the replacement of batteries, use exclusively gel batteries brand
Sonnenschein. Type: Dryfit A 512 / 55A (INVACARE Item No.: P50 992)
