Volta VT 4000 Tubular Battery 330Ah Price in Pakistan

The Volta VT 4000 belongs to Volta's Deep Cycle Tall Tubular series. It is a 12V, 330Ah flooded tubular battery with 9 plates. The VT 4000 is a deep cycle design, so repeated daily discharge is its normal job. With 330Ah it is the biggest battery in this whole group.

Backup time: a 12V 330Ah battery holds about 3960 watt-hours. Using only half of it (50% depth, which is kind to lead-acid) and allowing 85% inverter efficiency, the VT 4000 gives about 5.6 hours on a 300W load such as fans, lights and a router, and about 2.8 hours on a 600W load such as a fridge with two fans. This is the longest backup of any model in this group.

Best use: a 3 kVA or larger UPS, or a 24V or 48V solar inverter bank, where long backup matters. It suits big homes, clinics and shops with heavy loads.

Maintenance: large flooded batteries use more water when charged hard, so check every two to three weeks in summer and add distilled water only; see (How to Check Battery Water and Top It Up Safely). Place it on a strong stand in a ventilated area. Browse all Volta models at (Volta Battery prices). Order from Syed Non Custom Solar.

Buying advice: a 330Ah battery needs a strong charger. Before ordering, check that your UPS or solar inverter can deliver enough charging current; a small UPS charger will take a very long time to refill it and the battery may stay half charged. In a 48V bank of four VT 4000s you get close to 16 kilowatt-hours stored, which suits offices and large homes with big solar arrays. Given its size, ask for delivery to the final spot so it does not need to be carried up stairs twice.

How it compares: the VT 4000 has 80Ah more than the VT 2500 and 2 more plates (9 against 7). It also beats the largest Phoenix in our list, the TX-3500 (280Ah), by 50Ah, and has a stated warranty. For most medium homes the VT 1800 or VT 2500 is enough. Versus lithium, a 330Ah lead-acid bank is very heavy, while lithium is lighter and can use more of its capacity; see (Lithium vs Tubular Battery: Which Is Better for Solar?).
