I have personally found AGS as best locall brand in batteries & have utilise diffrent capacity Units in diffrent applications for ~3years of operation. Example (AGS 12V 3AH with Motor Cycle, 95D 31R with UPS, XL 85 & XL 100 with UPS, XR 85 with my Diesel car etc. The other good brand i have experineced is Phoenix which i have used for +2 years & still working.
Since~75% of Lead (Pb) used in new products is recylced & in Pakistan i think more than 95% of lead (Pb) is used by recycling.
During last 5 years the energy crises have been increased drastically hence inreases the demand of lead acid batteries but unfortunaltey during this period production quality of all the locall manufactureres have been decreased so regardless of brand u may face Battery failure too earliier.
Batteries specifically if used with UPS also face the Over charging issue, the MAx recomended charging current for Battery is 10% of its over all capacity but usually the cheap Quality non brnaded UPS gives excessive charging current which reducess the battery life.
Another issue is the availablity of propoer electrolyte. For prepration of Electrolyte good qaulity Salfuric acis shoud be mixed with Disteled water to achieve 12:50 specific gravity & should be cooled down to ambient temprature, after reconfirmation of SG the electrolyte should be filled to precise level in Battery shell & battery should be left unconnected for ~30 mins, after that BAttery should be fully charged which may take 5~10 Hours depending on capacity of battery. So after completing all these steps battery becomes ready for Long Operational life. But un fortunaltey bettery seller use TAP water & poor qulity Acid in dirty drume which are also fully exposed to dust & other garbage & Mostly the Specific Gravity is either low or high then the recomended SG. They also pour excessive amount of electrolyte that is full to Cell Cap
so the Batteries which are supposed to serve for 3~5 year just serve for 5~8 months.
