| Valve-regulated lead acid (VRLA) or absorbent glass mat (AGM) battery without „magic eye“ |
| t
| VLRA or AGM batteries are deep-cycle resistant and leak-proof. |
| t
| VRLA or AGM batteries are filled with electrolyte which is held in place in an „A“bsorbent „G“lass „M“at. The battery is sealed and equipped with valves. |
| t
| As the electrolyte is absorbed in the mat, these batteries cannot have a „magic eye“. Absorbent glass mat batteries are marked with „AGM“ on the battery. |
Note | t
| VLRA or AGM batteries cannot and must not be opened and must not be topped up with distilled water. |
| t
| Only perform visual inspections. |
Caution | Fitting a wrong battery will result in poor crash safety. |
| If a vehicle was originally equipped with a VRLA or AGM battery, only replace the battery with another VRLA or AGM battery. |
