Osaka HT-1000 Tubular Battery 78Ah Price in Pakistan

At 78Ah, the Osaka HT-1000 is the smallest battery in the HT tall tubular family, and it is aimed at homes with a light load and a small UPS. It is a 12V flooded battery with 5 plates. Its positive plates are tubes filled with active material, a design that copes with nightly discharge far better than a flat-plate car battery. It is sold by Syed Non Custom Solar with the live rate shown on this page.

Expect modest backup. Using our rule of Ah x 12 x 0.5 x 0.85 divided by watts, the HT-1000 runs a 300W load, roughly two or three fans, a few LED bulbs and a router, for about 1.3 hours. Add a fridge and push the load to 600W, and it drops to about 0.7 hours. Those figures assume a full charge and a healthy unit; short charging gaps between outages will cut them. The (Battery Backup Calculator) lets you try your own appliance list.

The best match is a 600 to 800 VA UPS that only has to carry the basics through one or two hours of load-shedding. In a flat, a shop counter or a small office, that is often enough. On solar it can work with a small inverter, but with this capacity keep the night load very light, or the battery will be drained too deep too often. Place it on a stand in an airy spot, out of direct sun.

Maintenance is simple. Check the water every four to six weeks, more often in peak summer, and top up with distilled water to the marker only. Never add acid. Clean white powder off the terminals and keep the nuts tight. The listed warranty is 12 months; ask how claims work before ordering and keep your bill. Heat and very deep discharge are what shorten tubular life, as (How Long Does a Tubular Battery Last in Pakistan?) explains.

Among its siblings, the HT-1800 keeps the same 5-plate count but jumps to 185Ah, more than double the backup, while the HT-4000 at 330Ah sits at the very top of the HT line. The older TA-1000 is rated 80Ah and may be a close relative, though it is listed separately, so check the label on the unit you receive. Next to lithium, the HT-1000 costs much less up front and can be serviced anywhere, but it gives less usable charge and needs water; (Lithium vs Tubular Battery: Which Is Better for Solar?) compares the two.
