Hyundai Sonata: Charging System / Battery Description and Operation
[AGM Battery]
AGM battery is used for especially heavy load on the vehicle
network depending on equipment and requirements. AGM stands for
Absorbent Glass Material Battery; that is absorbent glass fibre fleece.
AGM batteries are fitted in models with electrical loads/consumers which
have a high energy demand.
The constantly increasing energy demand of modern vehicle electrical systems calls for ever more powerful battery solutions.
The power consumption is considerable even when the vehicle is parked.
The somewhat higher price compared with a battery of similar size is fully balanced by the following benefits:
- |
Significantly longer service life |
- |
Increased starting reliability at low temperatures |

100 % freedom from maintenance |
- |
Low risk in event of an accident (reduced risk to the environment) |
