Why Do Warning Lights Come On After Honda Civic Battery Replacement?
One of the most common questions at the shop is, “Why do my warning lights come on after I changed the battery in my Honda Civic?”
Most people think that once they put a new battery in their car, the check engine light (CEL) or maintenance required light (MR) should go off. Unfortunately, it’s not that simple. It’s common for one or both of these lights to come on after changing your battery.
There are a few reasons why this might happen:
- The new battery may not be compatible with your car. This is rare, but it does happen. If you’ve bought a cheap aftermarket battery, it may not have the correct voltage or amperage for your car. This can cause electrical problems, including triggering the CEL or MR light.
- Your car’s computer may need to be reset. When you disconnect and reconnect, your battery can cause your car’s computer to lose memory. This can happen even if you disconnect and reconnect the battery correctly. As a result, your car may think something is wrong when there isn’t anything wrong. The fix for this is to reset your car’s computer by disconnecting the negative terminal of your battery for 30 seconds or so.
- There could be an actual problem with your car.
When to Change the Battery in a Honda Civic?
If your Honda Civic is from the 2001 or newer model, you should change the battery every four years. If your car is older than that, you should change it every three years. If you live in a hot climate, you may need to change it more often.
If your car’s battery is over four years old, it’s time for a replacement. Even if it’s not showing any signs of weakness, a battery only has a finite number of charge/discharge cycles before it needs to be replaced. Replacing your battery before it fails will save you the hassle and expense of being stranded on the side of the road with a dead battery.
If you live in a hot climate, your car’s battery will degrade faster than in a cooler temperature. The heat speeds up the chemical reaction inside the battery, causing it to lose capacity more quickly. For this reason, it’s a good idea to check your car’s battery every year or two and replace it if necessary.
If your Honda Civic has an older model year (2001 and below), then you should replace the battery every three years without fail. Newer Civics (2002 and up) can go for four years between replacements. Still, suppose you live in a hot climate region like Arizona or Florida. In that case, yearly checks are necessary to ensure optimal performance from your vehicle’s electrical system components – including the all-important battery!

What the Battery Charge Warning Lights Mean?
When your battery starts to die, your car will give you a warning. The battery charge warning light will come on, telling you it’s time to recharge it. If you don’t renew the battery, it will eventually die, and your car will no longer start.
There are two types of battery charge warning lights: red and yellow. A red battery charge warning light means the battery is critically low and must be recharged immediately. A yellow battery charge warning light indicates the battery is getting low and should be restored soon.
If you see either of these lights, recharge your battery immediately. If you let the battery die, it can cause permanent damage to your car’s electrical system.
