Osaka HT-2500 Tubular Battery 250Ah Overview
See the latest Osaka HT-2500 price in Pakistan here. The HT-2500 is a 12V 250Ah tall tubular battery from Osaka's HT ProMax Tall Tubular line, built with 7 plates. It suits homes with a 1.5 to 3 kVA system, usually as a pair in a 24V inverter or hybrid solar inverter, running fans, lights and a router. On a 300W load it gives about 4.2 hours of backup. Being flooded tubular, the HT-2500 needs simple distilled water top-ups and pays you back with long service in hot Pakistani summers.
Read full overview
The Osaka HT-2500 sits in the middle of the HT ProMax line: 250Ah at 12V on 7 plates. Osaka's page that once showed the TA-2500 now shows this model, which is why people still search for both names. It is a flooded tall tubular battery made for households that want a bigger cushion than a 200Ah unit gives. Syed Non Custom Solar stocks it, and the rate on this page is the live one.
Run the numbers with Ah x 12 x 0.5 x 0.85 / watts and the HT-2500 gives about 4.2 hours on a 300W fan, light and router load. With 600W, for example a fridge plus fans, it lasts about 2.1 hours. That extra hour over a 185Ah battery matters on days with long load-shedding blocks. Keep in mind that a tired charger or an old battery gives less. Try your own appliance list on the (Battery Backup Calculator).
The HT-2500 is a good fit for a 1.5 to 3 kVA system, usually as a pair in a 24V inverter or hybrid solar inverter. Paired with panels, it can be filled during sunny hours and carry the evening load. Because the battery is large, check that your inverter's charging current is high enough to bring it back to full each day. Keep it on a stand in a ventilated room, away from a hot roof or direct sun.
Water care is routine: every few weeks, look at the level indicator and refill with distilled water only, never past the top mark. Keep the top dry and the cable lugs tight, and grease them lightly to stop rust. The listed warranty is 12 months; please ask us about the claim process before ordering. Heat and deep draining are the two things that shorten life most, as (How Long Does a Tubular Battery Last in Pakistan?) explains.
Against its neighbours, the HT-2500 offers 25 percent more Ah than the HT-2000 (200Ah, 6 plates) and sits 30Ah below the HT-3500 (280Ah, 9 plates). If you want the same class from the Pro line, the Pro 230 is 20Ah smaller. Compared with lithium, it is cheaper at the start and easy to service, though it is heavier and only half its capacity is meant to be used; see (Lithium vs Tubular Battery: Which Is Better for Solar?) for the full picture.
