Battery Replacement: What to Know About Car Batteries

Battery Replacement: What to Know About Car Batteries

Oct 6th, 2017

Corcoran folks know that car batteries wear out just like any other battery and need to be replaced. There are a couple of things drivers should know when looking for new car batteries: one is cold cranking amps and the other is reserve capacity.

Let’s start with cold cranking amps. This can be thought of as the power output used to start a cold engine. The number of cold cranking amps you need depends on your vehicle and where you live in MN, specifically how cold it is where you live. The two factors are that the colder an engine is, the more power it takes to turn the engine over to get it started. It has all that cold, sluggish oil to contend with. The other factor is the chemical reaction in the battery that creates electrical energy is less efficient in the cold.

The colder it gets in Plymouth and Maple Grove, the more power is needed, but the available power drops. If you live where it’s cold, you need a battery with more cold cranking amps than you do where it’s moderate or hot. You should always get at least as many cold cranking amps as the recommends, but may want to upgrade if you live where it gets really cold.

An important note: car batteries may also list the Cranking Amps – CA – number. It is the Cold Cranking Amps – or CCA – that is the number here. CCA is the number to use in your comparisons of Corcoran auto batteries.

Now with all this talk of cold Corcoran temperatures, it’s for Corcoran drivers to note that heat is the real enemy of long battery life. In other words, the damage that’s done over the Minneapolis summer months shows up with the increased demands on the battery when MN weather turns cold.

Now on to reserve capacity: It’s a measurement of the number of minutes of reserve power the battery has at a given load. The number is more important these days because of parasitic drain. Parasitic drain is the battery energy that’s used when the key is off. So, the power drawn by the security system, the remote start system, even the power the computers require to maintain their memory.

Reserves are also needed when you make very short trips between Corcoran and Rogers or Maple Grove. You’re not driving long enough for the vehicle battery to recover the energy it used to start the engine.

So go with the minimum recommended by your and upgrade if you need more. Talk with your friendly and knowledgeable pros at Pro-Tech Auto Repair about options. If you need more from your vehicle battery, a high capacity battery may be called for. Batteries are a big ticket item, so the warranty gives piece of mind.
