STORAGE
11WARNING1WARNING
Always store batteries where they cannot be reached by
children. Contact with the battery’s sulfuric acid could
result in death or serious injury.
CAUTION
Do not allow battery to completely discharge. The elec-
trolyte in a discharged battery will freeze. The more dis-
charged a battery is, the more easily it can freeze and
crack the battery case. (00218a)
If the motorcycle will not be operated for several months,
such as during the winter season, remove the battery from
the motorcycle and fully charge. See CHARGING BATTERY.
See Figure 7-62. Self-discharge is a normal condition and
occurs continuously at a rate that depends on the ambient
temperature and the battery’s state of charge. Batteries dis-
charge at a faster rate at higher ambient temperatures. To
reduce the self-discharge rate, store battery in a cool (not
freezing), dry place.
Charge the battery every month if stored at temperatures
below 60˚ F. (16˚ C). Charge the battery more frequently if
stored in a warm area above 60˚ F. (16˚ C).
NOTE
The H-D Battery Tender Automatic Battery Charger (P/N
99863-93TA) may be used to maintain battery charge for
extended periods of time without risk of overcharging or boil-
ing.
When returning a battery to service after storage, refer to the
instructions under CHARGING BATTERY.
