If a regular run off the mill exide, AGS, FB battery is filled with 100% correct mixture made with lab grade H2SO4 and pure distilled 0TDS, neutral PH water at 1.270 SG measured at 20*C and charged for 3 hours as boost before putting into service. I can tell you from my own experience I have ran these batteries for more than 5 years at a time in Pakistan - the charging system of my cars were good and the battery level was topped about 4 times each year.
That is why I asked about the electrolyte, because unless you dont fulfill the premilinary requirements you cannot gather any data or expect any result - as there are too many uncontrolled variables.
For technical details - the batteries should follow standard ratings printed on them mainly
AH - amp hours
CCA - cold cranking amperes (how much constant amps a battery can put out at 0*C for 30 seconds before the cell voltage drops below 1.2) 7.2V total.
CA or HCA - cranking amps or hot cranking amps (how much constant amps a battery can put out at 26*C for 30 seconds before the cell voltages drop below 1.2) (7.2V total)
RC - reserve capacity measured in minutes, how much time a battery can sustain a draw of 25 amps at 26*C before the battery voltage drops below 10.5V
Size dimensions in mm (Pakistan follows metric system). and also the size model as set by the BCI group ratings.
With such data in hand - it makes clear boundaries for your customers and also protection of your company - If a customer complains that a battery is not performing as required - you can measure his requirement and compare to your technical specs and have a clean judgement. At the current moment, There is no information, so If a customer buys a smallish battery and kills it within a month because he wanted to run his super sized audio system and gets to claim warranty from your company over and over (its a giant loophole) Its not the customer who is in pain - its the company as they have to serve him fresh batteries under warranty becuase there is no data to measure anything.
So instead of having an ampere war between seth sahab and his freinds in which the customers are suffering, get the correct information out.
