how to disconnect car battery

Why do you need to hold down hardware?

Hold down hardware prevents excessive vibration. Vibration causes internal battery parts to break down. To minimize vibration effects, use special hold down hardware to secure the battery in place and prevent it from moving. Missing or loose hold down hardware can significantly shorten battery life.

What is AGM battery?

Some newer cars with absorbent glass mat (AGM) batteries require careful control of charging rates for maximum battery life, and the automaker may even alter the charging strategy as the battery ages.

How long does it take for a car battery to wear out?

Batteries gradually deteriorate until they can no longer provide enough power to start an engine. This wear time could take three to five years and a vehicle’s usage pattern is one factor contributing to the rate at which a battery will age.

Where to mount battery in car?

To combat this heat, automakers may mount the battery in an isolated area , install a heat shield over the battery, or relocate the battery outside the engine compartment, often under the back seat or trunk floor.

Does AAA battery tender work?

In either case, using a maintenance charger like AAA’s Battery Tender will keep the car battery fully charged and extend its service life.

Why do batteries break down?

Vibration causes internal battery parts to break down. To minimize vibration effects, use special hold down hardware to secure the battery in place and prevent it from moving. Missing or loose hold down hardware can significantly shorten battery life.

What type of batteries are used in cars?

Batteries are either conventional lead-acid or the more advanced AGM design previously mentioned. Most cars on the road today use conventional batteries and some models use AGM batteries. These batteries are highly spill resistant and better able to handle repeated discharging and recharging, as occurs in cars that have engine stop-start systems to improve fuel economy. Auto manufacturers optimize car-charging systems for the battery type so AAA recommends that your replacement battery always be the same type as the original factory-installed battery.
