CAUTION
WORKING WITH LEAD ACID BATTERIES AND BATTERY CHARGERS: All
lead acid batteries have the potential to emit gasses that may combine into a
combustible or explosive mixture. In many cases, it is possible that lead acid
batteries will emit these gasses during normal discharge and charging
operations. Because of this potential danger, it is important that you follow the
precautions recommended by both the battery and battery charger
manufacturers before using either one. For example, do not exceed the
recommended maximum recharge rate (charger output current limit), or remove
cell caps while charging flooded batteries.
CAUTION
CHARGER VOLTAGE COMPATIBILITY: NEVER use a battery charger unless
the battery voltage matches the output voltage rating of the charger. For
example, do not use a 12-volt charger with a 6-volt battery and vice-versa.
CHARGER LOCATION: LOCATE the charger as far away from the battery as is
allowed by the length of the output cable harness.
EXCESSIVE MOISTURE: Do not submerge the Solar Panel in any liquid.
CHARGER ATTACHMENTS: Do not use attachments that are not
recommended or sold by the charger manufacturer. To do otherwise may result
in the risk of electric shock, fire, or possibly some other unforeseen potential
personal injury situations.
MONITORING SEALED & NON-SEALED BATTERIES: When leaving a battery
charger connected to either a sealed (AGM or GEL) or non-sealed (flooded
battery) for extended periods of time (weeks, months, etc.), periodically check the
battery to see if it is unusually warm. This is an indication that the battery may
have a weak cell and that it could go into a thermal runaway condition. If the
battery releases an excessive amount of gas or if the battery gets hotter than
130F (55C) during charging, disconnect the charger and allow the battery to
cool. Overheating may result in plate distortion, internal shorting, drying out or
other damage. For flooded batteries, also check individual cell fluid levels
against manufacturer's recommendations for safe operation.


WARNING
ELECTRIC SPARK & OPEN FLAME: NEVER smoke or allow a source of
electric spark or open flame in the vicinity of the battery or engine. (For example:
Don't charge the battery next to a gas water heater.)
VENTILATION: Do not operate the charger where ventilation is restricted. The
intent here is to allow sufficient airflow to minimize and dissipate the heat
generated by the charger and to diffuse the gasses that may be emitted by the
battery.
CHARGER MAINTENANCE: NEVER DISASSEMBLE OR ATTEMPT TO DO
INTERNAL REPAIRS. THIS VOIDS THE WARRANTY. Assembling the
charger incorrectly may result in the risk of electric shock or create a fire hazard.
PERSONAL PRECAUTIONS
WARNING
WHEN YOU WORK NEAR LEAD-ACID BATTERIES:
1. Someone should be within range of your voice or close enough to come to
your aid if you have an accident;
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes;
3. Wear complete eye protection and protective clothing. Avoid touching your
eyes while working near a battery. If battery acid contacts your skin or
clothing, wash immediately with soap and water. If acid enters an eye,
immediately flood the eye with running cold water for at least 10 minutes and
get medical attention as soon as possible;
4. Be extra cautious when handling metal tools around a battery. If you drop a
metal tool near a battery it might spark or create a short circuit between the
battery terminals and some other metal part. Either event may cause a
dangerous electrical shock hazard, a fire, or even an explosion;
5. Remove all 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-circuited current high enough to weld a metal ring or other
piece of jewelry, causing a severe burn;
6

6. Use Battery Tender® Solar Chargers for charging 12V lead-acid or 12V
Lithium Ion batteries only. They are not intended to supply power to an
extra low-voltage electrical system or to charge dry-cell batteries. Charging
dry-cell batteries may cause them to burst and cause injury to persons and
damage to property;
INFORMATION NOTE ABOUT DRY-CELL BATTERIES:
There are some wet, non spillable, lead acid batteries on the market whose
manufacturers' make the claim that they are dry-cell batteries. These batteries
are sealed, gas-recombinant, starved electrolyte, possibly with AGM (Absorbed
Glass Mat) type construction. It is perfectly safe to use the Battery Tender®
Solar Charger to charge these types of batteries. The dry-cell battery warning is
intended for rechargeable or non-rechargeable alkaline and other similar types of
batteries. If you have any doubt about the type of battery that you have, please
contact the battery manufacturer before attempting to charge the battery.
7. NEVER charge a visibly damaged or frozen battery.
WARNING
IF THE BATTERY MUST BE REMOVED FROM THE VEHICLE:
1. To avoid an electric arc (or spark), turn off or disconnect all of the accessories
in the vehicle. Then always remove the cable that is connected to grounded
terminal from battery first;
2. If necessary, clean the battery terminals. Be careful to keep the corrosion and
other debris from coming in contact with your eyes;
3. If the battery is not a sealed battery, then if necessary, add distilled water to
each cell until the battery acid solution reaches the level specified by battery
manufacturer. Do not overfill;
4. Before connecting the charger to the solar panel, check the polarity of the
battery posts, and attach at least a 24 inch long 6 (AWG) insulated, battery
extension cable to the negative battery post. Then connect the appropriate
charger DC output connectors to the battery and the extension cable, positive
to positive and negative to negative. Never allow the alligator clips or terminal
rings to touch each other after they are connected to the battery charger.


WARNING
IF THE BATTERY REMAINS INSTALLED IN THE VEHICLE:
1. DO NOT CONNECT THE CHARGER’S OUTPUT LEADS TO THE SOLAR
PANEL UNTIL ALL OTHER CONNECTIONS ARE MADE!
2. Place and OUTPUT DC power cords in the best position to avoid accidental
damage by movable vehicle parts, i.e. hoods, doors, or moving engine parts
(fan blades, belts, or pulleys).
3. Check the polarity of the battery posts. If the positive (pos, p, +) post is
connected to the vehicle chassis, then the vehicle has a positive ground
system. If the negative (neg, n, -) post is connected to the vehicle chassis,
then the vehicle has a negative ground system. Negative ground systems are
the most common.
4. For negative ground systems, connect the positive (red) alligator clip, or ring
terminal to the positive battery post. Then connect the negative (black)
alligator clip, or ring terminal to the vehicle chassis. Do not make the negative
charger clip or ring connection to the carburetor, fuel lines, or thin, sheet metal
parts. Make that connection to the engine block or a heavy gauge metal part
of the frame.
5. For positive ground systems, connect the negative (black) alligator clip, or ring
terminal to the negative battery post. Then connect the positive (red) alligator
clip, or ring terminal to the vehicle chassis. Do not make the positive charger
clip or ring connection to the carburetor, fuel lines, or thin, sheet metal parts.
Make that connection to the engine block or a heavy gauge metal part of the
frame.

ADDITIONAL CHARGER INFORMATION
AUTOMATIC CHARGING AND BATTERY STATUS MONITORING: The
Battery Tender® Solar Charger is completely automatic and may be left
connected to both the solar panel 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 and the available input power from the solar panel.
Battery Tender® Solar Panels have a status light that indicates the operating
mode of the charger.
The Battery Tender® Solar Charge Panel charges up to 325mA (0.325 Amp-
Hour per hour). Therefore, a fully discharged 20 Amp-Hour battery will take
approximately 48 hours, to recharge to 80% capacity. Some large automotive or
marine, deep cycle type batteries may take several days to fully recharge.
Please note this condition assumes full sunlight and optimal tilt angle.
SPECIAL FEATURES: The Battery Tender ® Solar Panel has the following
special features:
BATTERY BACK FEED PROTECTION: The Solar panel has a special circuit
that prevents your battery from back charging into the Solar panel and draining
your battery.
WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY LOW
VOLTAGE: 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 %.
