Volta 3.96kWh Tubular Battery 12V (VT-4000)

Note: Volta rate the whole tubular range at over 1250 cycles at 80% depth of discharge, and the usable figure here is taken at that depth - the deepest Volta themselves test to, not a depth to hit daily. Tubular positive plates with thick negative plates, low-resistance PE separators, and float indicators so the electrolyte level is visible rather than guessed. Flooded, so it needs topping up and a ventilated space - not an indoor-cupboard battery. Built to IEC 60896-11. Capacity is quoted at the 20-hour rate. Jumbo Tall Tubular in Volta's range, 9 plates per cell. Overall height with terminals is 407 mm against a 370 mm container - size the battery box on the taller figure. 76 kg filled. Volta's own consumer price list of 13 March 2026 puts this at Rs 65,018 including 18% sales tax, which is a manufacturer list price rather than a street price. Volta is made by Pakistan Accumulators (Pvt) Limited, part of ACM Group, at Industrial Estate Hattar - the same plant, and the same moulds, as Osaka. The Osaka equivalent is a physically identical battery in different livery, so choose between them on price and on which dealer network is stronger near you, not on specification.
