![]() The polypropylene or hard rubber case which holds the battery plates, straps and electrolyte. ![]() Very important for the operation of snowmobile batteries. Number of amperes a lead-acid battery at 0oF (-17.8 ☌) can deliver for 30 seconds and maintain at least 1.2 volts per cell. An open circuit has a broken or disconnected path. The path followed by a flow of electrons. The quantity of current in ampere hours which a battery in a defined charge state can accept at a specified temperature and charge voltage within a defined period. There are six cells in a 12-volt lead-acid battery. The basic electrochemical current-producing unit in a battery consisting of a set of positive plates, negative plates, electrolyte, separators and casing. The ability of a fully charged battery to deliver a specified quantity of electricity (Amp-Hr, AH) at a given rate (Amp, A) over a definite period of time (Hr). The charging condition is determined by measuring of the acid density. Product release: Battery Chargers.īattery Test describes the test for determining the charging condition and electrolyte level of lead batteries with liquid electrolyte. Unit supplying electrical energy to a secondary battery. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes x 20 hours = 100 Amp-Hr of capacity.)īattery box containing the plate blocks, the connectors and the electrolyte. The unit of measure of the electron flow, or current, through a circuit.Ī unit of measure for a battery’s electrical storage capacity, obtained by multiplying the current in amperes by the time in hours of discharge. When an electrical circuit is created, these materials react with sulfuric acid during charging and discharging according to the following chemical reaction: PbO2 + Pb + 2H2SO4 = 2PbSO4 + 2H2O The active material in the positive plates is lead dioxide and that in the negative is metallic sponge lead. This stratification of acid can cause loss of capacity &/or caused by battery. This heavy acid drops as a result of gravitation to the lower part of the cell while lower density acid rises to the top of the cell. When charging a lead-acid cell, high density acid is produced in the plates. The distinguishing feature of an AGM battery. The mat of micro glass fibers which is used for absorbing the sulfuric acid in lead batteries. Battery terms from A to Z: The most important specialist terms for batteries.
