Make sure your battery and charging system are up to snuff.
You need to have us check the battery, charging system, and belts. Your battery can leave you stranded simply because it’s old and lousy. Or it could leave you stranded because your charging system isn’t working well, and the battery isn’t getting charged properly. So have your mechanic check the battery and charging system.
If you find that you need a new battery, get the biggest, meanest, ugliest battery that will fit in your car. Two things to remember about batteries: First, the battery that started your car easily in the summer may not have enough oomph to do it in winter. In winter, the engine is harder to start, because the oil isn’t as “fluid” as it was last July. And secondly, batteries lose power as the temperature drops (you remember your high school chem- istry, right?). So not only do you need MORE power to start the engine in winter, you also get LESS power from the same battery.
Batteries are rated by a measure called “cold cranking amps” (CCA), the maximum number of amps that the battery can deliver at zero degrees (F) for 30 seconds. Good, powerful batteries are rated at or above 600 CCA. We’ve never really liked this CCA rating because some batteries rated at 600 CCA can just barely make the 30-second criterion, and some can pump it out much longer - clearly better batteries. Along came our pals at Consumer Reports. When they rate batteries, they do the CCA test and report how long the battery puts out the 600 amps. Great, says us. So take a look at their ratings for the lowdown.
