The Discharge test was carried out as following, 6 PowerSafe 13 OPzS 1625 battery cells connected in parallel, batteries were at full charge, voltages verified using calibrated voltmeter, read to be 2.08 volt per cell. Discharge current set to 317A. Sulfuric acid (H2SO4) density was measured manually using Anton Paar, Density Meter DMA 35 calibrated tool at the beginning of the test for one cell (W26/4880), at 4:30 (90%), 4:45 (95%) and at the end of 5 hours (100%).
