AAA names four signs of a failing battery: a struggling engine start, vehicle warning lights, odd smells and corrosion on the battery terminals. In the 2022 Acura MDX owner's manual, a lit charging system indicator signals a charging system problem; Acura says to stop in a safe place and have a dealer check the vehicle immediately.

In the same manual, a sensor on the negative terminal monitors battery condition, and a battery warning message on the driver information interface points to a problem with that sensor. On models with Auto Idle Stop, the system may not activate when the charge is low, one of several conditions Acura lists.

• An engine that struggles to start
• A lit charging system indicator
• Battery sensor warning on the driver information interface
• Corrosion building up on the battery terminals
• Odd smells, which AAA lists as a warning sign

According to AAA, heat significantly shortens a car battery's life, reducing it from the typical 3 to 5 years to as low as 2 years. Ocala summers are hot, so a battery test at regular service visits is a sensible habit for any Acura driven in Marion County.

A AAA club publication explains why: rising temperatures evaporate the electrolyte, exposing the lead plates and causing internal damage, while heat also speeds corrosion. Cold brings strain too, since the 2022 Acura MDX owner's manual says battery performance degrades in cold conditions and may prevent the engine from starting.

• AAA's typical battery life: 3 to 5 years
• As low as 2 years in heat, AAA adds
• Evaporating electrolyte that exposes the lead plates
• Cold also degrades battery performance, per the Acura MDX manual
• AAA advice: test the battery before summer's peak

Battery replacement and battery service both sit on the Acura Accelerated Service menu at Jenkins Acura, and A1 and B1 visits include a battery test in the multi-point inspection. A weak result shows up in the electronic report and video the team sends, and you approve or decline the replacement from a phone or computer.

Acura specifies the battery for each model, and the service team installs the one specified for your Acura. The 2022 Acura MDX owner's manual explains why: a replacement must match the specified type and size, and on a model with Auto Idle Stop, a different battery may shorten battery life and keep the system from activating.

• Battery test within the A1 and B1 inspections
• Replacement matched to the type and size Acura specifies
• Inspection report and vehicle video sent electronically
• 2022 Acura MDX: AGM battery needs a compatible charger
• Genuine OEM parts, as the store's amenities list notes

The 2022 Acura MDX owner's manual says a battery gives off explosive hydrogen gas in normal operation and advises protective gear or a skilled technician for battery work. On the MDX Type S, the battery sits under a cargo-area cover, and the wrong battery, or one installed incorrectly, could leak hydrogen gas inside the vehicle, Acura warns.

If your Acura will not start, follow the owner's manual jump-starting procedure, which warns a battery can explode otherwise, then have the battery tested. Once a battery is reconnected, the stability, cruise control and tire pressure indicators may come on, and the manual says they should go off after a short drive above 12 mph.

• 2022 Acura MDX Type S: battery under a cargo-area cover
• Jump-start by the owner's manual, then a battery test
• Indicators that should clear after a short drive above 12 mph

• Home or office pick-up and delivery, subject to availability
