Ácido
Se refiere al ácido sulfúrico (H2 SO4), el componente activo del electrolito, o una mezcla de ácido sulfúrico y agua.
Active Material
The porous structure of lead compounds that produce and store electrical energy within a lead-acid battery. The active material in the positive plates is lead dioxide and that in the negative is metallic sponge lead. 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.
AGM (Absorbed Glass Mat)
A type of non-woven separator material comprised almost entirely of glass microfibers that absorbs and retains the electrolyte leaving no free electrolyte in the cell to spill. VRLA batteries made with this material are often referred to as “AGM” batteries.
Aleación
Como se usa en las baterías, una combinación homogénea de plomo y antimonio.
Corriente alterna
Corriente eléctrica que no fluye en una sola dirección, como la corriente continua, sino que cambia de dirección rápidamente o “alterna” la polaridad de manera que no carga la batería.
Amperio (Amp, A)
La unidad de medida de la tasa de flujo de la corriente eléctrica.
Ampere-Hour (Amp-Hr, Ah)
A unit of measure for a battery’s electrical storage capacity, obtained by multiplying the current in amperes by the time in hours of discharge. (Example: A battery that delivers 5 amperes for 20 hours delivers 5 amperes X 20 hours = 100 Amp-Hr of capacity).
