V-Glide Storage Continued:
5. Check the state of charge periodically.
Batteries that are discharged and left in a cold
environment can freeze and crack. If the spe-
cific gravity drops below 1.220, the batteries
should be recharged.
6. The frequency of recharging required will
depend on the temperature of the storage
area, but it is recommended that the batteries
be monitored for state of charge every month.
Also, if the storage area is unheated in a cold
climate and recharge is required, it is recom-
mended that the area be heated to at least
60°F prior to charge. Batteries do not charge effectively in cold temperatures for the same reasons that
they do not discharge as rapidly in cold temperatures.
PowerDrive System 48 Vehicles:
1. Keep the batteries clean and free of corrosion as outlined in the Battery Care Section.
2. Batteries should be wired in series so they can be connected to the charger. Batteries that are in cars
for winter storage can be left in the cars.
3. Fully charge the batteries prior to storage.
4. Store in a cool area. The colder the area in which the batteries are stored the less the batteries will self
discharge. Batteries stored at 0°F will discharge very little over a four-month period. Batteries stored at
80°F will have to be recharged every few weeks.
5. DS Electric vehicles with PowerDrive System 48 and PowerDrive Chargers are designed to be left con-
nected, with AC power to the charger on, during off-season storage. The on-board computer will auto-
matically analyze the batteries' state of charge every fifteen days and, if it finds the batteries low, will
activate the charger as necessary. When it is time to return the vehicle to service, the batteries will
already be fully charged.
