Daewoo 1.74kWh Deep-Cycle Battery 12V (DIB-180)

Note: Daewoo's Deep Cycle Technology line, the one they actually design for UPS and solar rather than for starting an engine, and the only Daewoo range carrying a 12-month free replacement warranty. Flooded flat-plate deep-cycle lead-acid: cheaper per nameplate kWh than tubular, shorter cycle life, and it needs topping up and ventilation. Compare it against a tubular battery on price per usable kWh over the life of the battery, not on sticker price. Daewoo publish no cycle life at all - not a number, not a curve, nothing at any depth of discharge. That is the single most important figure for a solar battery and its absence is the main thing to weigh against the price. The usable figure shown is derived at the 50% depth that flooded flat-plate lead-acid is conventionally sized around, not a manufacturer statement. Overall height is 256 mm with terminals against a 207 mm container - measure the taller figure into your battery box. 40 kg. Rs 45,312 is Daewoo's own current price on daewoobattery.com, which includes doorstep delivery and installation in major cities.
