Phoenix TX-1800 Tubular Battery 185Ah Price in Pakistan

The Phoenix TX-1800 is a 12V, 185Ah flooded tall tubular battery from the TX Power Cube series, with 5 plates. Tall tubular plates hold the active paste inside tubes, so the TX-1800 copes with daily UPS and solar cycling better than a flat-plate battery.

Backup time: a 12V 185Ah battery holds about 2220 watt-hours. Using only half of it (50% depth, which is kind to lead-acid) and allowing 85% inverter efficiency, the TX-1800 gives about 3.1 hours on a 300W load such as fans, lights and a router, and about 1.6 hours on a 600W load such as a fridge with two fans. This is why the TX-1800 is a popular all-round home size.

Best use: a 1.5 kVA UPS on one battery or a 2 to 3 kVA UPS as a 24V pair. It is one of the most popular sizes for a home that runs ceiling fans, LED lights, a TV and a router through load shedding, and it pairs well with a 12V or 24V solar inverter.

Maintenance: check the electrolyte level every three to four weeks in summer and add distilled water only; see (How to Check Battery Water and Top It Up Safely). Do not let the battery sit flat for days after a long outage, as that damages the plates. Warranty terms were not given in our data, so ask before ordering. For tips on making it last longer read (How Long Does a Tubular Battery Last in Pakistan?). Syed Non Custom Solar can deliver it to your city.

Pairing advice: if you build a 24V bank, buy both TX-1800s together so they age at the same rate. Two of them store about 4440 watt-hours, enough for a 2 to 3 kVA solar inverter to carry a medium home through a long evening cut. Mixing an old and a new battery in one bank makes the new one wear out early, so replace them as a pair.

How it compares: the TX-1800 has 25Ah more than the TX-1600 and 15Ah less than the TX-2000. Our data lists 5 plates for this model, fewer than the TX-1600 (7) and TX-2000 (9), so if plate count matters to you, check the label on the unit before buying. Versus lithium, the TX-1800 is the lower-cost route for a family that can keep up with water checks; lithium is lighter and needs no water but costs more at the start. See (Battery Backup Calculator) to size a lithium option.
