- Check your vehicle manual to learn original equipment manufacturer recommendations for the battery’s Group Size, Cold Cranking Amps (CCA) and Reserve Capacity requirements for your car or truck.
CCA is critical for good cranking ability while Reserve Capacity is important because it helps to power the vehicle’s electrical system in the event of alternator failure. CCA is the rating that shows the battery’s ability to deliver its rated amps for 30 seconds at 0°F while maintaining an operating level of at least 7.2 volts (1.2 volts per cell). CCA shows the battery’s ability to deliver its rated amps for 30 seconds at 0°F or -18°C
Reserve Capacity (RC) tells you how many minutes the battery can supply 25 amps of power at 80°F or 27°C without falling below 10.5 volts. In other words, it’s battery “staying power.”
- Beware of products that display only ratings like Hot Cranking Amps (HCA) or Cranking Amps (CA).
These products are tested at higher temperatures so the resulting numbers seem higher. Today’s automotive industry’s starting requirements are based on a CCA rating.
- Check for freshness.
Learn to read the battery date codes or ask the retailer to check them for you to purchase the freshest battery available. Batteries that sit on the shelf too long without recharge may not provide the performance you’ll need.
Freshness: You don’t want to buy an old battery because it may not deliver the power or life its label promises. With Interstate Batteries, we check the batteries on a regular basis so that you’ll always get POWER FAST...BUILT TO LAST!
- Check out the battery warranty.
Do you have to bring it back to the same facility where you purchased the battery?
How long is the free replacement period?
After that period, does the warranty work on a straight proration structure?
Is the warranty nationwide so that you can get service no matter where you’re driving?
Interstate Batteries has an impressive warranty to back its superior products. We offer an 18-month free replacement warranty on all automotive and the most popular commercial batteries we sell.
NOTE: A receipt may be required to replace the battery under warranty.
- Consider value, not just price.
The old adage “You get what you pay for” can be very true for batteries. Before you buy, ask a professional’s advice—perhaps your mechanic or counterman at your local parts store.
- If your battery tests weak, buy a new battery before your old one fails.
You could easily save yourself an expensive tow bill or repair. Have your battery tested before you leave on vacation and at periodic intervals like oil changes and tune ups. It’s one of the best ways to “start” each morning.
