Important Safety Instructions
- SAVE THESE INSTRUCTIONS
- Do not expose charger to rain or snow.
- Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to persons.
- To reduce the risk of damage to the electric plug and cord, pull by the plug rather than the cord when disconnecting the charger.
- An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
- That pins on the plug of the extension cord are the same number, size, and shape as those of the plug on the charger.
- That the extension cord is properly wired and in good electrical condition.
- That the wire size is large enough for the AC ampere rating of the charger as specified in Table 1.
- Do not operate the charger if it has received a sharp blow or is otherwise damaged in any way; take it to a qualified serviceman.
- Do not disassemble the charger; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.
- To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.
- Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts, which may cause an explosion.
- Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn
- Use the charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. Do not use the battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.
- NEVER charge a frozen battery.

USER INSTRUCTIONS
AUTOMATIC CHARGING AND BATTERY STATUS MONITORING:
Battery Tender® 800 chargers are completely automatic and may be left
connected to both AC power and to the battery that it is charging for long
periods of time. The charger output power, voltage, and current dependson the
condition of the battery it is charging. The Battery Tender® 800 charger has a
two-color 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 green and the charger
will switch to a storage/maintenance charge mode. The Battery Tender® 800
charger will automatically monitor and maintain the battery at full charge.
ATTENTION: The Battery Tender® 800 CHARGER HAS A SPARK FREE CIRCUITRY. The
output alligator clips or ring terminals will not spark when they are touched
together. The Battery Tender® 800 charger will not produce an output voltage
until it senses at least 3 volts from the battery. It must be connected to a
battery with the correct polarity before it will start charging a battery.
NOTE:
THE OUTPUT CLIPS OR RING TERMINALS MUST BE CONNECTED TO A BATTERY BEFORE THE
CHARGER CAN PRODUCE AN OUTPUT VOLTAGE.

WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY LOW VOLTAGE:
If you try to charge a dead battery having a voltage below 3 Volts, the
Battery Tender® 800 charger will not start. An internal safety circuit
prevents the charger from generating any output voltage unless it senses at
least 3 Volts at the charger output. In this situation, the AMBER light will
continue to flash, indicating that a charge has not been initiated.
NOTE:
If a 12 Volt, Lead-Acid battery has an output voltage of less than 9 volts
when it is at rest, when it is neither being charged nor supplying electrical
current to an external load, there is a good chance that the battery is
defective. As a frame of reference, a fully charged 12-Volt, Lead-Acid battery
will have a rest-state, no-load voltage of approximately 12.9 volts.
A fully discharged 12-Volt, Lead-Acid battery will have a rest-state, no-load
voltage of approximately 11.4 volts. That means that a voltage change of only
1.5 volts represents the full range of charge 0% to 100% on a 12-Volt, Lead-
Acid battery. Depending on the manufacturer, and the age of the battery, the
specific voltages will vary by a few tenths of a volt, but the 1.5- volt range
will still be a good indicator of the battery charge %.
- STATUS INDICATING LIGHT: If the light is not lit, then the battery is not properly connected and/or the charger is not plugged into AC power. The following describes light operation:
- RED LIGHT FLASHING – The RED light flashing indicates that the battery charger has AC power available and that the microprocessor is functioning properly. If the RED light continues to flash, then either the battery voltage is too low (less than 3 volts) or the output alligator clips or ring terminals are not connected correctly. The fuse in the output alligator clips or ring terminals may also be blown.
- RED LIGHT ON STEADY – Whenever the RED light is on steady, a battery is connected properly and the charger is charging the battery. The RED light will remain on until the charger completes the charging stage.
- GREEN LIGHT FLASHING –When the green light is flashing, the battery is greater than 80% charged and may be removed from the charger and used if necessary. Whenever possible, leave the battery on charge until the green light is solid.
- GREEN LIGHT ON STEADY –When the green light burns steady, the charge is complete and the battery can be returned to service if necessary. It can also stay connected to maintain the battery for an indefinite period of time
