CHARGER MAINTENANCE: NEVER disassemble the charger modules or
attempt to do internal repairs. Take it to a qualified service technician.
Assembling the charger incorrectly may result in the risk of electric shock or
create a fire hazard. Disassembly voids warranty.
WARNING
EXTENSION CORDS: Never plug an extension cord into modular marine base
plate receptacle. Only modular marine base plate plug can be used with an
extension cord. An extension cord should not be used unless absolutely
necessary. Using improper extension cord could result in a risk of fire and
electric shock. If extension cord must be used, make sure that:
 The pins on the extension cord plug have the same number, size,
and shape as those of the AC power cord plug on the charger;
 The extension cord is properly wired and is in good electrical
condition; and
 The wire size is as specified in Table 1 below.

PERSONAL PRECAUTIONS
WARNING
Battery posts, terminals and related accessories contain lead and
lead components, chemicals known to the State of California to
cause cancer and birth defects or other reproductive harm.
Always wash your hands after handling these devices.
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
4
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. Use DELTRAN BATTERY TENDER® POWER PRO Modular Marine
Battery Chargers for charging lead-acid 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
DELTRAN BATTERY TENDER® POWER PRO Modular Marine Battery
Chargers to charge these types of batteries. The dry-cell battery warning is
intended for 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.
PREPARING TO CHARGE: First, follow all General &
Personal Precautions as previously explained, and then
continue.
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 inserting the charger AC power plug into the electrical outlet, 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 terminal rings to touch each other after they are connected to the
