When you choose to buy a hybrid vehicle, whether it’s for the benefit of the environment or just to get more miles to the gallon, its efficiency depends on the battery. Toyota claims that the batteries in its hybrid cars should last for the life of the vehicle if it’s well cared for. However, faults can develop and it’s useful to know the warning signs of a dying battery. Here are five signs that you need to head to your dealer to get the battery checked out.
Fewer Miles to the Gallon
As a cost-conscious driver, you probably keep an eye on your gas mileage. A number of factors can affect your mpg, such as cold weather or incorrect tire pressure. But if you find yourself making visits to the gas station more frequently than usual, it could be that electric power isn’t taking over from your internal combustion engine (ICE) as often as it should. That could be an indication that the battery isn’t being charged to its full capacity or not retaining the charge for as long as you would expect.
Erratic Engine Input
If your ICE runs erratically, it’s another indication of a battery problem. The engine operating for longer than normal, or cutting in and stopping randomly, are things you need to have checked out. A number of issues could cause the problem, but it is most likely to be a sign of a dying battery.
State of Charge
Your hybrid car shows you the state of charge readings on the driver information display. If you notice significant fluctuations in the state of charge while you are driving, it is an indication of a problem. The fault could be with the charging system, but it’s more likely to be a symptom of a failing battery. Either way, it’s something that you need to have checked at your dealer’s service department.
Charging Problems
Your battery should discharge at a steady and predictable rate. However, several things can cause problems with the charging system and the battery is only as good as its charge. If the system is overcharging or undercharging the battery, or the battery is discharging at a high rate or has a parasitic drain, the life of the battery can be shortened.
Mechanical issues such as corrosion, damaged wiring, or bent pins can also have a detrimental effect on the charging system. If your car is fully charged when you park it overnight, but is low when you start it in the morning, your battery or charging system may be failing.
Strange Noises
The noise of a constantly running fan means that your battery is getting too hot, which is bad for the battery and the nearby components. You need to get it checked as soon as possible or the problem will get worse.
Whether a warning light tells you there’s a problem or you experience any of the above symptoms, the expert technicians at Burien Toyota can diagnose the fault and advise you if you need a new battery.
