No battery manufacturer in Pakistan writes any rating on their batteries. They simply write the model nos. which are useless unless we get some manual to decipher them. The guys selling them at shops dont know jack, jill, andaa, aaloo or anything about batteries - for them its maal, itnay ka khareed itnay ka farokht. I hate such business people.
If the battery is maintained correct chemically only then can you measure its performance. My mercedes benz has a genuine MB battery, its flooded type, with 100 AH rating, 900CA and 780CCA. with H8 dimension size. Its date stamp says 2007 - still cranks the engine quick. I have had to replenish some distilled H20 in it twice in a year.
With such info - I can choose to buy a battery of any manufacturer that meets these requirements, not possible with Exide, FB, AGS or any brand in Pakistan as they dont sell European style batteries, just like they dont like to sell proper electrolyte - It would be a deal killer on sales, and saith sb wont be able to buy his new BMW 7 series sedan.
