Selection Guide; what battery to buy for my car audio system
What's a good battery for car audio? The factors highlighted below will help make an informed decision even as look at different variations offered by manufacturers.
Cold-Cranking Amps (CCA) and Reserve-Capacity
This is the ability of the battery to power the audio system in cold temperatures. A battery’s CCA should match the amount of watts produced and the higher the number of CCA the higher the amount of power produced. As such you should always look out for these two elements.
Size and Fitting
The size should fit properly in the battery tray provided. You should check the dimensions provided in the user manual to see if it will fit. The positioning of the terminals should also be correct. This is important because just as with your primary car battery, loose audio battery will results into vibrations which will eventually damage the battery itself and consequently the audio system.
Care and Maintenance of the Battery
Ideally, your battery will either require some little maintenance or no maintenance at all. Those that require little maintenance comes in unsealed design where you can add water occasionally before you can eventually replace them. Those that don’t require maintenance, on the other hand, are completely sealed allowing for only replacements in case of any damage.
Just like other batteries, car audio batteries power units can get damaged if they are not charged for some time. Any battery that has exceeded six months since it was manufactured should be avoided as it is likely that it has lost some power.
Price of the Battery
They are two major divisions of batteries that determine the price tag; wet- cells and dry-cell units. The dry-cell units are more expensive than the wet cell and they serves longer. Wet-cell, on the other hand, are inferior to the dry cell only that they power the stereo system a bit faster when compared to the dry cell.
The Bottom Line
A second audio battery for car audio is a crucial accessory as it relieves the main car battery of the burden of powering your sound system. Picking a durable and high performing one will assure you of many years of short and long trips with the desired level of entertainment.
Before you settle on any battery for your car audio, you need to look at the kind of battery that is best for your car. It should be a reliable source of power that will deliver optimal performance.
