14) FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR
THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A
SPARK NEAR BATTERY:
a) Check polarity of battery posts. 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, +) post of battery.
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 battery when making 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) A marine (boat) battery must be removed and charged on shore. To charge it on
board requires equipment specially designed for marine use.
DANGER – Never alter the AC cord or plug provided – if it will not fit the outlet, have a proper
outlet installed by a qualified electrician. Improper connection can result in a risk of
an electric shock.

USER INSTRUCTIONS
AUTOMATIC CHARGING
MONITORING:
DELTRAN BATTERY TENDER
completely automatic and may be left connected to both AC power and to
the battery that it is charging for long periods of time. However, it is prudent
to periodically check both the battery and the charger for normal operation
during these extended charging periods.
The charger output power, voltage, and current all depend on the condition
of the battery that is being charged. The DELTRAN BATTERY TENDER
charger has a two-colored LED indicator light that provides a visual means
to determine the operating mode of the charger and hence the condition of
the battery connected to the charger.
The two-colored status indicator LED light is available to determine whether
the charger is operating in one of the 4 primary charge modes:
Qualification/Initialization mode: The Monitor Circuit verifies appropriate
battery voltage levels and good electrical continuity between the battery
and the charger DC output. The bulk mode (full charge, constant current,
battery is 0% to 80% charged), the absorption mode (high constant
voltage, battery is 80% to 100% charged), or the storage/float
maintenance mode (low constant voltage, battery is 100% to 103%
charged).
When the battery is fully charged, the LED will turn solid GREEN and the
charger will switch to a storage/maintenance charge mode. The Battery
®
Tender charger will automatically monitor and maintain the battery at full
charge.
Battery Recovery Mode:
If you try to charge a dead 12-volt Lithium battery with a very low voltage, 4
to 8 Volts, the DELTRAN BATTERY TENDER
battery charger will automatically switch into the Recovery Mode. When in
this mode the LED will alternate between Green and Amber. If successful
and once complete the charger will then return to a solid RED LED and
automatically switch back to the normal charge cycle.
There is a three (3) hour time limit for this recovery process. If not
successful the LED will first turn solid Green then flash Amber five (5)
times. It will continue this sequence until the charger is disconnected from
the AC source. If this happens there is a good chance that the battery has
already been damaged due to the low voltage and cannot be recovered.
ATTENTION: The Battery Tender
CIRCUITRY. The output alligator clips or ring terminals will not spark when
they are touched together. The Battery Tender
output voltage until it senses at least 4 volts from the battery. It must be
connected to a battery with the correct polarity before it will start charging a
battery.
