Our Favourite Car Batteries

1.ACDelco 48AGM

The ACDelco 48AGM is a long-lasting battery that comes with an insurance plan. It is highly charged receptive and has lengthy cycling capabilities thanks to its AGM technology. The battery can stop and start your car with almost no maintenance procedures or glitches involved. The ACDelco 48AGM is immune to spills and leaks because the electrolyte is held permanently in the glass mat separator. The battery’s oxygen recombination mechanism reduces water loss and provides a maintenance-free performance.

The constant pressure maintained in the plates reduces the active mass that the grid loses. As such, the car battery can last longer than traditional batteries. The ACDelco 48AGM also comes with a 36-month free battery replacement plan. However, the battery terminals, posts and other linked spots contain lead compounds, which can cause grave health problems like reproductive health complications and cancer.
