7.0 VEHICLE STORAGE (ov
er 6 weeks)
7.1 BATTERY PREPARATION
Before storage make sure batteries are fully charged and the electrolyte is full in all cells per Section 4.2. Clean the
batteries and connections per Section 4.3.
The Delta-Q charger has the capability to test and recharge batteries during storage. Leave the batteries connected
and the Delta-Q charger plugged into a reliable AC source.
If the Delta-Q is not used:
Batteries will "self-discharge” during storage and recharging will be necessary. Table B indicates the frequency
for recharging.
The specific gravity of the electrolyte should be checked every 6 to 8 weeks using a hydrometer. See Section
4.7 for further details.
The batteries should be recharged to a specific gravity of approximately 1.260 sp. gr.
After charging, disconnect the battery pack. See Section 2.4.
Batteries in a low state of charge will freeze at higher temperatures than fully charged batteries. Do not
attempt to charge a battery that is frozen or if battery case is excessively bulged. Properly dispose of
battery, because frozen batteries can explode.
Table C indicates freezing points of batteries at different specific gravities.

For vehicles with a single point watering system, quarterly during storage check water levels per Section 4.10.
7.2 VEHICLE PREPARATION
Store the vehicle in a cool place.
Maintain tire pressure at sidewall recommendation.
Grease suspension and continue quarterly lubrication during storage period.
Clean vehicle body, seats, battery compartment and vehicle underside.
Do not engage park brake. Block wheels to prevent movement.
NOTICE: Make sure power keyswitch is in the OFF position.
7.3 RETURNING VEHICLE TO SERVICE
If necessary, connect the battery pack and fully recharge batteries.
Check tire pressure and readjust if necessary. See Section 1.4.
Complete pre-operation check per Section 3.5.
For vehicles with a single point watering system:
After the batteries have been fully charged, connect the system to its water supply for 3-5 seconds then
disconnect regardless of whether or not the batteries are completely full.
Return the vehicle to its regular service.
Place the vehicle back into its regular watering schedule (waiting at least 1 week until next watering).
