Charging Batteries - Invacare STORM Service Manual

12.2 Charging the Batteries
CAUTION:
• Careful when testing / charging. Do not bridge the battery poles.

NOTE:
Also observe the information on battery charging
provided
• in the User’s Manual of the STORM
• in the User’s Manual of the charger,
• on the front and back of the charger.
For care and maintenance of the battery’s mechanical
components, see chapter 12.1.

• Status display at joystick box
blinking 7x (fully discharged)?
• Status display at joystick box
blinking 8x (excess voltage)?
• Measuring voltage at the
batteries:
- Voltage below 11,5 V?
- Voltage below 9,5 V?
(Battery fully discharged.)
• Voltage difference
(Tolerance ±0,2 V) in the two
batteries?
Charging Process
CAUTION:
• The batteries are not permitted to lie on their sides or up-end during the charging process. The
battery poles must point upwards.
• In the STORM with ACS, only batteries of type Dryfit A 512 / 55A may be used.
• Batteries and charger must be exposed to the same ambient temperature, since the charging
process, among other factors, is controlled by temperature sensors. Extended charging cables
and different locations of charger and batteries result in a faulty charging.

NOTE
• Procedure when charging the batteries with the INVACARE charger:
Also see the STORM’s User’s Manual.
• Observe the following order when connecting the INVACARE charger:
First connect the charging plug, then the mains plug.
• Fully discharged batteries cannot be charged with the INVACARE charger
• If the batteries cannot be fully charged, they must be replaced.
• When fully charged, the display “Full Charge” on the charger must light up.
As soon as a charging voltage of 28 V is achieved, the LED’s on the joystick box will flash additionally.
The voltage of an individual battery at full charge and room temperature must amount to
(approx. 20 - 22°C) 14 ±0,2 V.
