Observe that the connectors are clean and free of sulfate, as it corrodes the metal in addition to preventing the flow of electrical current.
Take care of your car from extreme temperatures. Remember that heat causes it to overheat and winter causes the battery to discharge.
Check that the lights are not on when you park or any other device since there is a possibility that when you return the battery is low and your vehicle will not start.
Deep cycle batteries store energy so that the sources of electric current recharge them through alternators, solar panels, windmills, etc. They use an AGM storage technology.
The fundamental difference between these batteries and short-cycle batteries such as those of an automobile, lies in the use that one makes of them.
Sulfation is a normal part of battery operation and occurs when the battery is discharged. When the battery is recharged, the sulphation (lead sulfate) is transformed back into active material.
If the battery is left discharged for a period of time, this sulfation slowly transforms until it cannot be converted back into active material, and thus, after charging, the battery will not be able to return to its original performance. If the sulfation is severe enough, the car will not start. This is the problem that is usually called sulfation.
