Lead Acid Battery Testing

 
The Battery Testing Laboratory is set up to do full specification testing of Start Lighting Ignition (SLI) lead-acid batteries according to IEC60095-1 (2006) and SANS2:2013.
 
Current capabilities allow the Battery Testing Laboratory to test up to 21 batteries simultaneously using its 16 channel x 100A and 5 channel x 50A 0-18V testers, where channels can be paralleled for higher current testing requirements.  The facilities have equipment that can perform cranking capability tests on batteries with currents up to 2000A and temperatures down to -40°C. The laboratory can also perform endurance type testing using its vibrational testers that can go up to at 30m.s-2 and 50 m.s-2 (22-30Hz) respectively. 
 
 
 
The facility is equipped to test up to 60 batteries with its four uniquely designed high temperature water baths, which allows testing of lead acid batteries at temperatures up to 85°C. Some of the unique pieces of equipment can evaluate SLI batteries according to the new start-stop requirements that were introduced by car manufacturers in order to be compliant to international requirements to reduce global carbon emissions. The bidirectional tester will allow for the simulation of drive patterns typically generated by start-stop vehicles under laboratory conditions. The testing equipment will be the only service offered in South Africa enabling uYilo to facilitate local battery manufacturers to develop batteries using specially developed testing sequences unique to South African driving conditions.
 
The uYilo Battery Testing Laboratory offers a variety of testing services, which includes, but not limited to:
  • Capacity Testing
  • Cold Crank Ability (Discharge currents up to 2,000A)
  • Endurance tests for batteries (Cycling at elevated temperatures)
  • Charge Acceptance
  • Dynamic Charge Acceptance
  • Charge Retention
  • Water consumption
  • Vibration resistance (with and without battery load)
  • Electrolyte retention tests
  • Post mortem (Teardown) analysis
