LOAD TESTING
A BATTERY
E30 AND D40
SERIES

LOAD TESTING
A BATTERY

• You will need a Digital
  Volt Ohm Meter

LOAD Testing
A Battery
 

• 2 Jumper Wires
  with Alligator Clip
  on each end

1.Turn the Key Switch off, remove
cover (s) as needed, this will
provide access to the batteries
 

2. Once the Cover (s) have been
removed pull back the rubber post
covers from the Main Positive &
Negative Battery Post

3. Connect the jumper wire to the
Positive and Negative on the 
Multimeter lead ends

4. Connect the other end of the
jumper wire to Main Battery
Positive & Negative
terminal ends by sliding it under the
eyelet next to the battery post
 

5. Get a Near capacity load to lift load
test the batteries

6. Set the meter to the 200 Volt D/C

6. Note your Static Battery Voltage

A general rule of thumb a Maximum
of 10% voltage drop under load

6. Note (write your Static Battery Voltage down)

The rule of thumb is a Maximum
Voltage drop of 10% under load
(example 25.0 x0.10 = 2.5)

7. Lift the load and note the meter
reading at it smallest number

6. Note (write your Static Battery Voltage down)

The rule of thumb is a Maximum
Voltage drop of 10% under load
(example 25.0 x0.10 = 2.5)

7. Lift the load and note the meter
reading at it smallest number

8. Subtract your Load test voltage from the 
Static voltage (25.0-24.4=.6) ,
This will give you your voltage drop (.6)

This example would indicate the batteries
are OK
