Wait a few minutes and test again ⇒ page 19 .

Note

If you have performed test at jump-start point and message does

not disappear, perform test directly on battery.

2.7

Current draw test

WARNING

Batteries where the magic eye is colourless or light yellow must

not be checked or charged. Do not slave/jump start the vehicle!

Danger of explosion when checking and charging or slave/

jump starting

These batteries must be renewed.

Note

♦ Ensure that the correct charging mode is set on the charger

so that the current draw test is not falsified.

♦ VAS 5095 A ⇒ page 26

♦ VAS 5900 ⇒ page 30

♦ VAS 5903 ⇒ page 41

To quickly ascertain the state of discharged batteries, the battery

current draw test whilst charging helps to determine whether the

battery must be replaced or fully recharged.

Note

For battery tester with printer -VAS 6161- , the current draw test

must always be performed when the test result „Perform current

draw test“ appears on the display.

The current draw test must be carried out when the test result with

battery tester with printer -VAS 5097A- is as follows:

1 - Starting output sufficient

2 - Starting output poor

3 - Starting output very poor

4 - Cannot be tested – charge battery and repeat test.

- and when the tester will not switch on (no LED, no printout)

Depending on the test result ⇒ page 13 with battery tester with

printer -VAS 5097A- , further procedures or tests may be required

before making a final decision on the condition of the battery.

Performing a current draw test whilst charging a battery will quick‐

ly establish whether a partly or fully discharged battery

⇒ page 59 can be recharged to return it to a serviceable condi‐

tion.

Test requirements

♦ When charging a battery, battery temperature must be at least

≥ +10 °C.

♦ The charger must be capable of outputting a charge current of

at least 30 A, as for example with VAS 5095A, VAS 5900, VAS

5903

♦ The battery's current draw must be measured with a current

pick-up clamp, e.g. VAS 5051B/7, when charging with battery

charger -VAS 5095A- . Battery charger -VAS 5900- and bat‐

tery charger -VAS 5903- display the current draw on the unit.

– Connect battery to battery charger and start charging se‐

quence.

– Measure charging current of battery after 5 minutes.

Test result:

If the current draw A is higher than 10 % of the nominal capacity

(e.g. > 6.1 A for a 61 Ah battery), fully charge battery and test

again.

Note

For Eos with two 6V absorbent glass mat batteries, the charge

current must only be 5 % higher than the nominal capacity of the

battery. Example for Eos: the 50 Ah battery must have a charge

current higher than 2.5 A after 5 minutes of starting the charging

sequence.

– Fully charge the battery when the charge current is higher than

10 % of the nominal capacity (observe exception for Eos in

above note).

– Perform battery test after allowing battery to rest for two hours

⇒ page 9 .

If the charge current, in amperes, lies below 10 % of the nominal

capacity after 5 minutes of starting the charging sequence (5 %

for the 2 x 6 volt batteries in Eos) (example for 50 Ah battery <

5A), renew battery. For Guarantee and ex-gratia cases: complete

battery test sheet and keep it with the battery.

2.8

Checking no-load voltage of battery on

stock and stored vehicles

WARNING

Danger of injury! Observe warning notices and safety regula‐

tions ⇒ page 2 !

Note

♦ The no-load voltage test may only be carried out to assess the

condition of the battery on stock and stored vehicles within the

framework of prescribed maintenance.

♦ The no-load test serves to determine whether a battery on a

stock or stored vehicle requires recharging ⇒ Maintenance

tables „Service for stock and stored vehicles“ .

Special tools and workshop equipment required
