Electrical - Battery Maintenance Information
Date: January 27, 2009
Order No.: S-B-54.10/213
Supersedes:
Group: 54
SUBJECT:
MY- All, Models 164, 171, 199, 203, 204, 209, 211, 216, 219, 221, 230, 251, 463
Battery Maintenance
The vehicle battery must be checked periodically on vehicles that remain inactive for extended periods of time. The maximum allowable time
between performing battery checks is 4 weeks. In the event that a vehicle is going to be stored for more than 4 weeks, it is recommended to
disconnect the ground lead at the battery. This will prevent battery discharge by quiescent current (rest current) draw from the vehicle's
no-load current consumers.
NOTE:
If it is deemed necessary to charge the on-board electrical system battery and the vehicle is equipped with more than one battery, then the
starter battery must also be charged. On vehicles with more than one battery, ground leads should be disconnected from all batteries
equipped on the vehicle including the on-board electrical system battery, starter battery and the auxiliary/additional battery (G1/7).
Check the battery voltage of the on-board electrical system battery via the instrument cluster or multimeter, as described in AR54.10-P-1132A.
A battery should be charged when the measured voltage drops below 12.2 V.
If the vehicle has been inactive for 6 months or longer, prior to putting the vehicle back in service, the batteries must be charged to counteract
any effect of self-discharge. If equipped, the auxiliary/additional battery (G1/7) does not need to be recharged, just reattach the ground lead for
this battery.
NOTE:
The instrument cluster displays a white battery symbol with the text "Visit Workshop," if the auxiliary/additional battery voltage is < 11.5
V.
If the auxiliary/additional battery is < 11.5 V and > 6.0 V, this battery will be charged by the Front SAM (N10/1) at a charge rate of 150 mA,
when the engine is running or STAR Diagnosis is left connected and set to charge the auxiliary battery. If the measured voltage of the
auxiliary/additional battery is < 6.0 V, the battery should be replaced.
Battery maintenance is the responsibility of the dealer for all new vehicles in dealer inventory. Batteries replaced and claimed as warranty
while the vehicle is in dealer inventory, other then auxiliary/additional batteries, are subject to debit. Additionally, the customer is responsible
for battery maintenance when vehicles remain inactive for extended periods of time.
