    Default Dry battery or conventional (acid filled) battery

    Dear fellows,

    I am looking to buy new battery for my UPS. Someone recommend me dry batteries as it has greater life (like 1 or 2 years additional) as compare to conventional ones. Plus ones they are dead, can be sold out at half of its current market value.

    I haven't tried dry batteries before so little hesitant because it is not like drain old acid and put new acid and charge to get it in life.

    Thanks in advance

    Good quality dry Battery (AGM or Gel type) costs twice as a flooded battery of same capacity and can perform more than twice time of flooded battery provided you assure normal operating conditions but the mostly local made UPS/invertors providing unthrottled charge current & Voltage will damage them more quickly than of a flooded battery so if u are sure that ur UPS can charge them as per manufactureres recomendations then they will perform very well other wise its better to stay with Flooded battery.

    I agree with you bro. I also searched over the internet and found that dry batteries are good but not for our local made UPS. They are not optimal at charging so it would be better to stuck with wet batteries.

    Thanks.

    I havent used dry batteries (maintenance free) on my UPS but I'm using one in my car and one for my generator. I have been using dry batteries for almost 3 years now. They are way way better than conventional acid cell batteries. They last atleast 50% more longer than conventional batteries.

    Dry batteries are good If they are getting proper voltage for backup. My dry batteryt for ups dried out working for just after 4-months, I got my UPS checked any dey said battery is not working properly and for that time I even lost the warranty card aswell for the replacement. It is working uptil now but wont last more then 30min's after one hour loadshedding.

    Mayb I ll go for conventional this time or not sure yet.
    between If you have UPS more then 1kwatts den dont just get single dry battery, for larger more den 185amp or 2 batteries for that UPS,
    2 batteries for larger UPS are must according to my knowledge.
    do leme know Which battery you plan to buy.

    I have one 1KVA. It is a branded UPS note like local ones. And it requires two batteries no matter big or small. I have a plan to put two 85amps battery which will sum up as 170 amps. I have a maximum load of 2 fans and 2 tubelights.

    Ihope It is,
    but I would suggest try using one 120-140amp battry and other one 85amp as yu stated.
    because to my concerns Iwas having a single 185amp wid load of one side 4fans and 6energy savers.IKVA is UPS is designed to handle such load but with a single 185amp It never worked.

    you can gor for 85amp 2 batteries aswell as yu have lesser load, but do one time thing, make sure you have one larger battery and one shorter for the backup and make that sum up of total 225amp or 230 amp. Do ask your UPS provider to.

    are you going for conventional ones?

    If u have branded UPS then Sealed ( AGM or Gel) will serve u very well.

    dry batteries
    expensive
    long life
    extra backup time
    no maintenance
    running well at 80% load

    Liquid batteries
    Cheep
    maintenance
    short backup
    can't bear extra load

    I am also using dry batteries since 2010 (200amp two batteries with homage inverter)

    wet AGS battery is good. i used AGS 60 from 2011 june in honda city. now in feb 2016 it is working well. after 5 years it is old and i can sold it in rs800 and buy new AGS in rs 4500. 3600 need to buy new battery. dry battery is not so good and it is not cheap like AGS,exide,osaka. after a month we should check water level in engine radiator,battery,wiper bottle. so i think that wet battery is good than dry. life may be same but price is not same.
