Auto Test

Auto Test


The aim of this test is to exercise batteries to maintain optimum performance. This is the recommended method in routine maintenance of batteries.

The Auto Test reconditions Nickel chamistry batteries that do not reach target capacity. Reconditioning is to deep discharge below 1V/cell with a controlled current so that the large crystals inside the battery can be broken down to restore the battery to full capacity. This applied to all Nickel-based batteries.

Other chemistry rechargeable batteries are not reconditioned, but exercised instead. Batteries in use are typically cycled every three months on Auto. If batteries are failing prematurely, increase frequency of service by Auto testing.

Procedure and Standard

The battery is first cycled to determine it's true capacity. If NiCd and NiMH batteries do not meet the target capacity at the end of a discharge cycle, they are reconditioned to reduce battery memory. Following recondition, the battery is cycled again to determine the recovered or final capacity. The battery is fully charged before test finishes.

SLA, Li-ion and LiPh batteries are cycled once. If it fails, another cycled will be carried out again. Reconditioning is not performed for these batteries. The duration of Auto Test is:

  • 2.5 to 10 hours for Nickel chemistry batteries
  • 20 t 40 hours for SLA
  • 6 to 20 hours for Li-ion and LiPh with default C-codes.


Result Sample

Detailed display shows cell voltage, analyser charge or discharge current in mA, battery temperature and duration of service. Batteries considered in good condition shall be greater than 80% under recommended test settings of manufacturing datasheet.

Note: C5100B can only test Li-ion battery up to 7.4V using batterystore software (comes with the C5100B unit)
