Amplifier deep cycle batteries - Car Audio Power Cell

Car Battery (Amp Battery)manufacturers set the concentration of the sulfuric acid in the electrolyte of a fully charged wet battery to optimize the capacity, service life, water consumption, use in float applications, high discharge rate capability, battery size and self discharge rate. When the Specific Gravity is increased on purpose or by additives, the following occurs: capacity, service life, water consumption, high discharge rate capability, and self discharge rate all increase and use in float applications and battery size decrease. When you decrease the Specific Gravity, the reserves occurs. You might ask why increasing the Specific Gravity on wet starting and motive deep cycle batteries is not a good thing? The answer is that it also accelerates the corrosion of the positive plate grids and connecting straps and you could have a premature battery failure; thus effecting overall service life, but clearly there might be some short termed gains at the expense of increased watering and service life.

Normally, unless there is a spill, battery acid should never be added to a battery. If the temperature compensated Specific Gravity reading needs to be increased in a cell for whatever reason, remove a small amount of some the existing electrolyte and replace it with fresh battery acid with a 1.300 Specific Gravity. Repeat the process until the cell matches the Specific Gravity readings of the rest of the cells or, if the battery is fully charged, the manufacturer's temperature compensated recommended value for a fully charged cell. If the temperature compensated Specific Gravity reading needs to be decreased in a cell for whatever reason, remove a small amount of some the existing electrolyte and replace it with distilled, deionized or demineralized water. Repeat the process until the cell matches the Specific Gravity readings of the rest of the cells or, if the battery is fully charged, the manufacturer's temperature compensated recommended value for a fully charged cell. Some typical Specific Gravity readings at 80° F (26.7° C) for full charged cells are:

* 1.300-1.310 for wet motive deep cycle batteries with tubular positive plates

* 1.267-1.284 for wet motive Deep Cycle batteries with solid lead positive plates

* 1.260-1.270 for wet Starting batteries with pasted plates

* 1.215-1.250 for wet stationary Deep Cycle batteries with solid lead positive plates
