Key Features to Look For
Your car battery is super important. Here are the things you should check:
1. Amp-Hours (Ah):
This tells you how much power the battery can hold. A higher Ah rating means more power for your sound system. A powerful sound system needs a higher Ah battery. Think of it like a bigger gas tank for your music.

CCA tells you how well the battery starts your car in cold weather. A higher CCA is better, especially if you live where it gets cold. You want your car to start easily, even in winter.
3. Reserve Capacity (RC):
RC shows how long the battery can power your car if the alternator fails. A higher RC is better. This gives you more time to get help if something goes wrong.
4. Battery Type:
There are different types of batteries.
- Flooded Lead-Acid: These are the most common and affordable. They need regular maintenance.
- AGM (Absorbent Glass Mat): These are sealed and maintenance-free. They’re good for sound systems.
