the imported so called MF batteries are actually calcium alloy lead acid batteries - they are wet just like regular exide ones.. The difference is that they do not evaporate their electrolyte fast enough to reduce level.
my experience of properly making electrolyte with lab grade H2SO4 and lab grade distilled acid at 1.270 SG will make a difference of night and day with any battery whether pakistani or imported.
I use pak origin batteries with this electrolyte and they can crank up any big starter for any amount of time - and actually last
