The

battery is completely sealed so access to its interior is not possible.

But you can do a periodic inspection checking that:

  1. Check that the mounting brackets are tight.
  2. Terminals are clean and tightened. Use a brush to clean them if needed.
  3. Perform a periodic review of your vehicles charging system to ensure that the battery is operating under normal conditions and that there are no faults in the electrical system that may affect the normal life of your battery.

There are other factors that could impact the normal performance of the battery:

  1. Charging System: Overcharge or undercharge shortens the life of the battery. It is generally provoked by failure of the alternator, voltage regulator or the alternator strap.
  2. Frequent Discharges: Frequent deep discharges will eventually damage your battery. If your battery is discharged, charge it immediately to avoid further damage.
  3. Engine Tuning: When your vehicle takes too long to start, it is unnecessarily demanding energy from the battery. Check the ignition system and the carburetor.
  4. Loose support system: If your battery is not properly strapped to the tray, it can suffer physical damage.
