WARNING     

EXTENSION CORDS:

  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: 

Ø 

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; 

Ø 

The extension cord is properly wired and is in good electrical 
condition; and 

Ø 

The

 

wire size is as specified in Table 1 below.   

 

TABLE 1:  EXTENSION CORD  

LENGTH & MINIMUM SAFE CONDUCTOR SIZE 

              Note:  The smaller the AWG number, the larger the conductor diameter. 

  Length of Cord  (feet) 

 

6 to 100 

 101 to150  

  Length of Cord  (meters)             1.8 to 30.5 

30.8 to 45.6

 

  Size of Conductor  (AWG) 

     18

  Conductor Diameter  (mm) 

    1.25                   1.5 

 

WARNING     

Do not operate the charger with damaged AC power cords 
or plugs or DC output cords or accessories - replace them 
immediately. 

 

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 

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

 VRW Power Tender Plus 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® VRW POWER TENDER PLUS 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 alligator clips or terminal rings to touch each other after 
they are connected to the battery charger. 

5.  Connect the AC power plug to the electrical outlet.
