Keep an eye on you battery health and replacing it when it's low can prevent other problems from cropping up in your engine, the mechanic claimed.
He added that a low battery can lead to “voltage spikes,” which can backfire on the vehicle.

Road users who give their part a single check occasionally pay only ten percent of the price.
He revealed the tip on his YouTube channel, which focuses on improving and minimizing drivers' experiences repair costs.
On his channel, Scotty said: “Because modern cars are all controlled by computers, if the battery goes really bad the car can still start, but the electricity is so low that the alternator has to supply too much electricity.
“You can get power surges that destroy computer parts.
“My advice is: if it says your battery has less than 30 percent left, buy another battery.”
According to BookMyGarage, new batteries can cost up to £100 in the UK.
However, the final bill may vary depending on a number of factors, such as the type of car and the duration stated on the battery product.
The expert mechanic added that not replacing the battery when it is weak could result in drivers having to replace their alternator in the future, which is significantly more expensive.
Motorists can check their battery life with a simple diagnostic test, which costs as little as £30 from some providers.
Halfords is currently offering a free battery health check on its website.
Leading breakdown experts and car insurance specialists at the RAC also offer health checks.
Advanced technology can check whether the condition of a battery is deteriorating and whether it needs to be replaced immediately.
Diagnostic checks can also determine if there is a problem with a vehicle's charging and starting system.
