Daewoo 1.86kWh Deep-Cycle Battery 12V (DSS-220)

Note: Daewoo's Super Value Series, built on what they call MaxPlus thick-plate technology - an optimised grid with additives for better conductivity. It is the budget line: the warranty is 6 months against the DIB range's 12, which tells you where Daewoo themselves rank it. 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 254 mm with terminals against a 210 mm container - measure the taller figure into your battery box. Rs 44,368 is Daewoo's own current price on daewoobattery.com, which includes doorstep delivery and installation in major cities.
