Battery TestingA. Visual CheckA1.0 Confirm warranty period applicable to the battery and itsusage• Warranty periods and exclusions are listed in catalogue• A1.1 Confirm not fraudulent claimAre warranty terms met?• YES – Continue to A2.0• NO – Reject ClaimA2.0 Does the battery leak?• No – Go to A4.0• Yes – Go to A3.0A3.0 Can external damage be seen in the area of leak?• No – Continue go to A3.1• Yes – Reject Claim, Determine cause of damageA3.1 Has the battery been overfilled by the customer• No – Accept Claim• Yes – Reject ClaimA4.0 Are the end walls of battery badly swollen?• NO – Continue to section B, battery testing• YES – Reject Claim• Suspect Overdischarge/Overcharging• Sulphation is not a manufacturing defectB1. Digital Testing – All batteriesDue to an increasing number of sealed, totally maintenancefree batteries in the market place, acid specific gravity readingscan not always be taken, therefore we recommend a test usinga recognised digital conductance tester (Midtronics/BoschBAT121). Battery terminals should be clean to ensure ameaningful result. In the absence of specialist conductancetesters, section A Visual Check and section C High Rate Testshould be used.MIDTRONICS1. Select the SAE Testing mode2. Enter 70% of the SAE Rating of the battery (shown on thelabel of battery).a. For Marine and Leisure Batteries use 4 x 20hr capacitye.g. 100Ah Marine battery test @ 400A3. Continue to Testa. For earlier 415 model, there is no automatictemperature compensation, every °C drop below 20°Cequates to approximately 4A loss in Midtronic readingGOOD BATTERY• Reject Claim• Battery is fully charged and ready to useGOOD + RECHARGE• Reject Claim• Recharge Battery, then ready to useCHARGE + RETEST• Charge Battery, then test regain• If same result appears after charging• Reject Claim• The battery has been subjected to excessive charge /discharging cycling during service• Check vehicle electrical system for defects• Check any non OEM fitted electrical consumers• Check for extreme service usage, (Minicabs, deliveryvehicles)• Service life can be significantly reduced by electricalload/charging imbalance and stop/start drivingThese are not manufacturing defects.REPLACE BATTERY• Reject Claim• Battery has lost performance due to external factors• The battery has lost significantly its original performance• The battery has lost performance due to external factors,such as overcharging, undercharging, deep cycling, wearand tearThese are not manufacturing defects.BAD CELL BATTERY• Accept Claim• Battery is defective, replace battery under terms andconditions of warranty• Note, if repeated claim from one fleet user, furtherinvestigation of battery usage is required especially if thebattery is overdischarging and overchargingTEST NOT POSSIBLE/CHECK CONNECTION• Check tester leads (another battery) and ensure terminalsare clean• Switch off all electrical consumers when testing the battery ifstill fitted to the vehicle• Check Battery Voltage with multimeter, if Voltage > 0 Volts.Disconnect Battery from vehicle then recharge/retestNO DISPLAY• Confirm Battery Voltage = 0 Volts with multimeter• Accept ClaimBOSCH BAT1211. Select the SAE or EN mode2. Enter 65% of the SAE Rating of the battery (shown on thelabel of the battery).a. For Marine and Leisure Batteries use 90% of (4 x 20hour capacity shown on top label of battery)3. Continue to Testa. Adjust for temperatureb. Note Reading between Bosch and Midtronic tester varysignificantly hence recommended use of 90% rating forBosch testerGOOD BATTERY• Reject Claim• Battery is fully charged and ready to useGOOD + RECHARGE• Reject Claim• Recharge Battery, then ready to useCHARGE + RETEST• Charge Battery, then test regain• If same result appears after charging• Reject Claim• The battery has been subjected to excessive charge /discharging cycling during service.• Check vehicle electrical system for defects• Check any non OEM fitted electrical consumers• Check for extreme service usage, (Minicabs, deliveryvehicles)• Service life can be significantly reduced by electricalload/charging imbalance and stop/start drivingThese are not manufacturing defects.REPLACE BATTERY/UNSERVICEABLE• Reject Claim• Battery has lost performance due to external factors• The battery has lost significantly its original performanceBattery TestingYUASA - The world's leading battery manufacturer507
