B1.Testing the Battery<br />
B1 Using Recognised Digital tester - Batteries without removable vent plugs<br />
We recommend that a test is carried out with a recognised digital tester, for example Midtronic or Bosch Type 121 tester<br />
In the absence of specialised testing equipment perform a high rate discharge test (go directly to Procedure B2 )<br />
B1<br />
If testing <strong>battery</strong> on vehicle, you must remove surface charge<br />
With engine off, switch on lights for 1 minute then switch off all electrical loads and leave for 2 minutes prior to testing<br />
Before testing, ensure <strong>battery</strong> terminals are clean and tester leads are in good condition<br />

Leave to<br />
stand for<br />
4 hour<br />
minimum<br />
Choose the correct SAE testing mode<br />
Select the SAE CCA rating shown on the<br />
label of <strong>battery</strong>*<br />
* For Marine, Leisure Batteries use<br />
4x 20 hour rating<br />
Choose the correct SAE testing mode<br />
Select 90% of SAE CCA rating shown on the top<br />
label of <strong>battery</strong>*<br />
* For Marine, Leisure Batteries use<br />
4x 20 hour rating<br />
Leave to<br />
stand for<br />
4 hour<br />

RECHARGE<br />
BATTERY<br />
Press the Test Key<br />
Typically Midtronics reading are reduced by<br />
4A for every °C loss in temperature<br />
Latest models - automatically adjust for temperature.<br />
For Earlier Midtronic 415 tester use * key<br />
Press the Test Key<br />
*Note Data differs considerably from Midtronic tester,<br />
hence reason for use of 90% rating for testing<br />
suspect warranty batteries<br />
Use arrow keys to adjust for temperature<br />

GOOD BATTERY<br />
Battery is fully charged and ready to use<br />
REJECT CLAIM<br />
GOOD + RECHARGE<br />
Charge <strong>battery</strong> then ready for use<br />
REJECT CLAIM<br />
GOOD + RECHARGE<br />
Charge <strong>battery</strong> then ready for use<br />
REJECT CLAIM<br />
CHARGE + RETEST<br />
Charge <strong>battery</strong> and test again If same results<br />
appear after charging then<br />
REJECT CLAIM*<br />
CHARGE + RETEST<br />
Charge <strong>battery</strong> and test again If same results<br />
appear after charging then<br />
REJECT CLAIM*<br />
REPLACE BATTERY<br />
Battery has lost performance due to<br />
external factors<br />
REJECT CLAIM**<br />
BAD CELL BATTERY<br />
Battery is defective => ACCEPT CLAIM<br />
Replace under warranty terms and conditions<br />
If repeated failures from one fleet customer, further<br />
investigation of <strong>battery</strong> overdischarge is required<br />
TEST NOT POSSIBLE / CHECK CONNECTION<br />
No display - check tester leads contact<br />
Check Voltage with digital multimeter as <strong>battery</strong><br />
could be deeply discharged<br />
Switch off all electrical consumers when testing a<br />
<strong>battery</strong> fitted to a vehicle.<br />
Multimeter OK , but not Midtronics, then disconnect<br />
<strong>battery</strong> from car and retest<br />
NO DISPLAY<br />
Despite GOOD CONTACT and RECHARGING<br />
Check Voltage with digital multimeter<br />
If Voltage = 0 volts ACCEPT CLAIM<br />
REPLACE BATTERY / UNSERVICEABLE<br />
Battery has lost performance due to external factors<br />
Is Start capability less than 60% then<br />
REJECT CLAIM** (using 90% of label rating)<br />
REPLACE BATTERY / CELL SHORT CIRCUIT<br />
Battery is defective => ACCEPT CLAIM<br />
Replace under warranty terms and conditions<br />
If repeated failures from one fleet customer, further<br />
investigation of <strong>battery</strong> overdischarge is required<br />
TEST NOT POSSIBLE / CHECK CONNECTION<br />
No display - check tester leads contact<br />

If Voltage = 0 volts ACCEPT CLAIM<br />
Recommended<br />
Equipment<br />
A voltage meter to<br />
check Open Circuit<br />
Voltage<br />
A recognised brand<br />
digital tester (eg<br />
Midtronics)<br />
A variable high rate<br />
discharge tester to<br />
check/confirm the<br />
batteries ability to start<br />
the vehicle<br />
A hydrometer to check<br />
acid specific gravity and<br />
condition<br />
A good quality charger<br />
to enable discharged<br />
units to be recharged<br />
Battery Testing<br />
Note<br />
* <strong>The</strong> <strong>battery</strong> has been subjected to excessive charge/discharge whilst in use.This may be a malfunction of the vehicle charging system, as a result of excessive electrical<br />
consumers, infrequent vehicle usage or extreme operating conditions (eg Mini cabs service or delivery vehicles) <strong>The</strong>se are not Manufacturing Defects.<br />
** <strong>The</strong> <strong>battery</strong> can no longer deliver performance compatible with the original specification, the <strong>battery</strong> has lost performance due to outside factors, overcharging, undercharging,<br />
deep cycling, wear and tear. <strong>The</strong>se are not Manufacturing Defects.<br />
