Incoming Inspection: Analyzing elements of lead alloy through Baird FSQ spectrogragh. Choosing factories free from inspection for export as original material suppliers. Using pure electrolyte. Keeping impure content of seperators under 10PPM.
Plate Process Control: Grids casted by Wirtz-produced caster weight tolerence is 2g and thickness tolerance is 0.03mm. Grids pasted by MAC-produced pasters to assure consistency of active materials. Plates formed by Tank-Formation 3-Step Charging Method adopted to assure plate consistency Assembly Control: To test pressure between group terminals in assembling cells To fill acid by precise acid-fillers in keeping acid tolerance under 1ml to assure no free acid.
Battery Test: Discharge test carried by micro-computer- controled Charge-and-discharger. To test internal resistance, open voltage, max currency discharge and leakage by 4-function testers. To inspect batteries at random according to International Standard. To test all functions by Germanproduced DIGATRON according to the requirements of customers.
