Battery for UPS - Tubular or TRUCK

I have a 3KVA UPS (2300-2400 watts) which has been using two 175 Ampere AGS batteries. Conventional batteries.

While it has been 2 years now, I will need to change the batteries soon. I have come across these TUBULAR batteries also known as DEEP CYCLE batteries by AGS, OSAKA AND DAEWOO.

AGS is making deep cycle batteries for solar and UPS and the maximum size it makes is 165 Ampere retailing for 25,000 rupees a piece.

Daewoo is making deep cycle battery too by model name DIB 225 AND DIB 260, these are larger than AGS deep cycle but do not mention any specs like AGS does on its website.

Osaka Tubular batteries come under model TA1800 AND TA 2000.

Can you guys please recommend which deep cycle battery would be best for transformer based sine wave ups? I am inclined towards OSAKA due to larger capacity than AGS. Daewoo is risky investment
Prices are same for most brands. Daewoo is a bit expensive from AGS and Osaka..

I will need 2 pieces, please mention how your experience has been with the 3 brands in terms of deep cycle batteries for since wave UPS.

Thanks!

DAEWOO reviews are not very encouraging.

Osaka Tubular batteries are used at Cellular RBS for backup and have very positive reports.

165 AH regular truck batteries are also good if used with refined electrolyte and charge is controlled. Easy to handle for maintenance

@capsat Sir ...

What would you recommend for 3KVA transformer based SINE WAVE UPS
1. https://abl.atlas.pk/product/dc-110-2/
2. Osaka tubular TA 1800

Both of these are tubular i think. Not sure about the new AGS one.

I need two batteries 175 ampere + please recommend for longer life and more backup time.

Do deep cycle batteries give better backup on ups?

only phoenix tubular is good osaka volta and fujika all made by same factory makes horrible tubulars
either go with phoenix or new deep discharge cycle batteries by ags
and if you can set the float charge values below or equal to 13.3 and charging upto 14.1 max amps to 18-20
this will prolong your battery life if using a 24 v system double the values
