Web19 okt. 2007 · If 1 amp is measured at t 0, and 900 mA is measured 100 ms later, the average charge taken from the battery is 0.095 coulombs over the 100 ms interval. If this average current flow continues for an hour, the discharge rate is 0.95 A-h. The smallest measurable charge quanta are set by the time between measurements and current … WebFor batteries with free acid, the specific weight (density) can be measured. It is about 1.10-1.12 for a discharged battery and 1.26-1.28 for a fully charged battery. For Gel/AGM battery, the density cannot be measured to determine the charge state. Instead, measure the battery’s rest voltage is a good way to get an idea of the charge rate.
