My electrician brother recommends me Ags. And with his UPS AGS GIVES so much better result than company made least feature containing inverters or fake local ups.
After 2 years of using the AGS battery 175 amp. It no does not charge higher than 60%. But gives 1 hour backup on ceiling plus 5 energy savers. And 3-5 hour backup on all energy savers.
I used to abuse my ags battery suchh as usig AC water which had impurities. Then mom went to another country so battery was not used for 1 month. Then came back and we recharged the battery from shop and our electric meter was cut by wapda after 2 months and to resolve the issue. It took 1 more month. So again battery not in use for those days. And then after mentioning which water i was using. My brother electrician friend scolded me for abusing the battery so much.
Now i only use AGS battery water and its good. And charges till 60%. And because ups tries to charge it to 100% but it doesn't so ups stops after trying for 10-15 minutes. And when battery voltage or power dies a little so it starts charging again. Thats why niw i have to replace water every month.
Otherwise with his ups which never overcharges. I seldom refilled water. Maybe 2-3 times in a year. With 8 hour backup when battery was new.
Inverters kill the batteries. Batteries do not die them-self especially if good company batteries.
Batteries are victim of inverter or cheap local made ups Abuse.
Good luck.
