Can I switch from a standard car battery to AGM?

Yes, in some cars it is possible to replace a standard lead-acid battery with an AGM battery.

AGM batteries have several advantages, but it is important to check that the car’s charging system is compatible with the battery type.

What do I need to check?

• That the AGM battery has the correct voltage.

• That its capacity and starting current meet the car’s requirements.

• That its dimensions, terminal layout and mounting fit.

• That the car’s charging system can handle the AGM battery.

• Whether the car requires the battery replacement to be registered or coded.
  

Is AGM always better than a standard car battery?
Not necessarily.

AGM can be beneficial in cars with high electrical loads or start/stop systems, but does not automatically improve every vehicle.

If the car is designed for a particular battery type, it is normally best to follow the manufacturer’s recommendation.

Can I switch from AGM to a standard battery?
This is not normally recommended if the car was originally fitted with AGM and requires that battery technology.

A standard battery may struggle to cope with the car’s charging and load patterns.
