More about batteries:

Batteries come in a variety of sizes and power.  Also, the positive terminal is sometimes on the left side, and sometimes it is on the right side.  When you choose a battery you need to have one that is correct for your vehicle.  If your battery is too big, it will not fit in the spot dedicated for a battery.  Forcing it into a tight space (and yes I have seen this) causes wires to be unusually pushed aside,  and because it’s too big the hold down strap cannot be used.  If the battery is too small, the hold down straps cannot hold the battery in place.  Therefore, when you get a battery you need to be sure you get the right sized battery. 

Batteries are measured in “Amps.”  A typical battery for a Honda is rated about 550 amps.  A battery for a large V-8 is rated about 750 amps.  Amps are a measure of ‘oomph.’  A bigger engine needs more oomph to get it to crank than a small engine.  When you buy a battery you need to get one with the right size and the right oomph. 

How long will my battery last?

Good question.  Generally, the less you pay for a battery the shorter its life span.  Batteries age, and as they age they have less power to start your car.  I use Interstate Batteries because they guarantee (pro rated) their batteries for at least 75 months.  Additionally, if one of their batteries needs replacing within the first 24 months, they are replaced for FREE!  I could buy less expensive batteries, but I don’t want my customers to become stranded.  I have seen batteries that are only guaranteed for 24 months.  That’s not very long.

Most batteries are easily replaced, but as manufacturers shrink cars, they have come up with some unusually places for their batteries.  I have seen batteries in the trunk, under the rear seat and some are inside the wheel well.
