Engine cranks slowly when being started.
A slow cranking engine could mean that your battery is beginning to fail. It’s best to first check all battery connections as well as the starter and fuel system to determine the root cause.
Lights dim or problems with electronic/electrical devices, such as electric windows or locks.
As with slow starting, lights that dim or electric windows and locks that are slow to operate may indicate that the battery is compromised in some way.
Engine won’t start after sitting overnight or after it was just turned off.
If the battery will not operate properly after being idle for several hours, or after the engine is started and shut off, this issue may indicate that the battery is near end of life.
Accessory runtime is decreasing.
Hotel loads on the vehicle require higher reserve capacity. If DVD players, lights or other additional accessory runtime is needed, a heavy-duty battery should be considered.
Additional loads are added to the vehicle.
As more additional loads are added to the vehicle such as a microwave, fans, etc., there will be greater demand on the battery. To get the longest battery life, a larger capacity/heavy-duty battery is needed.
Vehicle is operated in high vibration environments.
Battery life is impacted by high vibration, so if a vehicle is frequently exposed to harsh environments, a heavy-duty battery with increased vibration resistance is needed for the optimal life outcome.
