6.0 VEHICLE STORAGE (over 6 weeks)
6.1 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.
Recharging will be necessary during storage. Frequency for recharging is as follows:

The specific gravity of the electrolyte should be checked every 6 to 8 weeks using a hydrometer. See
Section 4.6.
The batteries should be recharged as necessary to a specific gravity of approximately 1.260 sp. gr.
After
charging, disconnect the batteries. See Section 2.6.
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. Frozen
batteries can explode
. Properly dispose of the battery.
Table C indicates freezing points of batteries at different specific gravities.

6.2 VEHICLE PREPARATION
 Store the vehicle in a cool place.
 Maintain tire pressure at sidewall recommendation.
 Clean vehicle body, battery compartment and vehicle underside.
 Block wheels to prevent movement.
NOTICE: Make sure keyswitch is in the OFF position.
6.3 RETURNING VEHICLE TO SERVICE
 If necessary, connect the battery pack and fully recharge batteries.
 Check tire pressure and readjust if necessary.
 Perform the pre-operation checks per Section 3.4.4.
