17. FOLLOW THESE STEPS WHEN BATTERY
IS OUTSIDE VEHICLE. A SPARK NEAR
BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK OF
A SPARK NEAR BATTERY:
a) Check polarity of battery terminals. POSITIVE (POS, P, +) battery post usually has
a larger diameter than NEGATIVE (NEG, N, -) post.
b) Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to
NEGATIVE (NEG, N, -) battery post.
c) Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) battery of post.
d) Position yourself and free end of cable as far away from battery as possible – then
connect NEGATIVE (BLACK) charger clip to free end of cable.
e) Do not face the battery when making the final connection.
f) When disconnecting charger, always do so in reverse sequence of connecting
procedure and break first connection while as far away from battery as practical.
g) When disconnecting charger, disconnect in reverse sequence from connecting
procedure. See operating instructions for charge information.
h) A marine (boat) battery must be removed and charged on shore. To charge it on
board requires equipment specially designed for marine use.
The battery charger must be connected to the battery according to
the instructions above.
IMPORTANT SAFETY INFORMATION!
The MULTI US 25000 cannot be used to restore a fully worn out battery.
If the MULTI US 25000 does not switch to maintenance charge after three days (green
light illuminated), there is a fault. Possible causes:
• The battery is probably worn out and should be replaced.
• Some large antimony batteries may behave different and can allow the
MULTI US 25000 to charge the battery for too long, which can lead to overcharging.
See caution!
• If heavy power consumers like fitted alarms and navigation computers are connected to
the battery, the charging process takes longer and this can also overcharge the battery.
• A sulphated battery will only accept current with difficulty, and consequently the charg-
ing process takes a particularly long time. A worn out battery cannot be fully charged.
Therefore you should always check whether the charger has been switched to mainte-
nance charge before you leave it turned on or unobserved for longer periods.
