BU-802a: How does Rising Internal Resistance affect Performance? So using about 500 mA and seeing how long it takes will give a measure of battery capacity. Evaluate individual cells for replacement. If the levels are low but covering the plates, completely charge with a good quality smart charger (battery minder, schumacher), then check the specific gravity; I would want no more total check over here
It also has a switch that turns on a very low-resistance dummy load. An analogy for this is trying to determine how much water an odd-shaped tank will hold. Försök igen senare. Finished Size: 50mmX37mmX17mm (length X width X height maximum position size, contains copper foot height).
