A car battery can be compared to the muscle system of a human body. It provides the energy required to start the engine and run electric systems. Unfortunately, very few car owners pay attention to their battery, let alone follow a good maintenance schedule. Over time, a poorly maintained battery begins to slow your car down and warrants replacement. However, there are other reasons why your car battery might need replacing. This article highlights signs that your vehicle needs a new car battery. 

Slow Starts

One of the first signs that your battery is in dire need of replacement is a slow starting engine. If you turn on the ignition and hear the engine struggling to pick for a couple of seconds, the chances are high that it is depleted. A worn-out battery is less effective because the plates cannot transfer energy to the engine fast enough. It forces the engine to struggle for a few seconds before stored energy reaches the ignition system. When you realise that your engine is starting slow, replace the battery immediately. It is usually a sign that your battery is about to die, and you do not want it to happen when you are in the middle of nowhere.   

Battery Case Deformation

Batteries, whether old or new, must maintain a rectangular shape. However, factors such as extreme temperatures can do a number on a battery casing and interfere with its shape and consequently the durability. Therefore, when inspecting a battery's terminals, always look at its shape. If it is anything but rectangular, then you should start thinking about replacing the battery. The reason is that a malformed battery is susceptible to swelling, cracking and leaking. When this happens, the acid damages other components under the hood, leading to costly repairs.  

Severely Corroded Terminals

The terminals on a new battery are clean and allow for unhindered energy transfer to the engine. Over time, the terminals begin to oxidise, and the white ashy substance forms a barrier between the terminals and connectors. If you do not get rid of this residue, the terminals experience corrosion. In mild cases, the corrosion leads to a voltage surge, which might damage electronic components. In severe cases, the rust gradually eats away the terminals until they are no more. Consequently, the connectors are left with nothing to clutch to, and the only remedy is to buy a new battery.
