Goodyear 12V Auxiliary AGM Battery Group 400 14Ah — 200 CCA, 22RC, Maintenance-Free

The Goodyear AUX14-AGM is a compact 12V, 14Ah absorbed glass mat (AGM) auxiliary battery designed to deliver reliable 200 CCA starting power and dependable reserve runtime for accessories and electronic systems.

This Platinum-series Goodyear auxiliary battery combines sealed AGM construction with a durable build to give extra starting assistance and stable power for vehicles, boats, RVs, and off-grid accessories. Its compact Group Size 400 footprint and multiple mounting positions make it a practical supplemental battery where space is limited. Built to resist vibration and temperature swings, it arrives with mounting screws included and a 36-month warranty for added confidence.

How much starting power and runtime does this battery provide?

The AUX14-AGM supplies 200 cold cranking amps (CCA) for strong cold-weather starts and a 22-minute reserve capacity (RC) to support electronics when the engine is off. It’s tuned to offer higher discharge rates than everyday lead-acid cells, so accessories keep running longer between charges.

• 200 CCA for reliable starting in low temperatures
• 22 minutes reserve capacity for accessory power when idle
• 14 Ah nominal capacity for compact auxiliary needs

What installation options and physical specs should I know?

This Group Size 400 battery measures 5.87 x 3.37 x 5.62 inches and allows multiple mounting orientations except upside down, which helps in tight engine bays or cramped compartments. Terminals are easily identified with positive on the left and negative on the right; screws for installation are included, though wiring harnesses and brackets are not.

• Dimensions: 5.87 x 3.37 x 5.62 inches for compact fit
• Mounting: flexible placement; do not mount upside down
• Polarity: positive left, negative right for quick hookup

How durable and maintenance-free is the AGM construction?

Sealed AGM technology makes the battery spill-proof and resilient against shocks and vibration, which is useful in off-road, marine, and mobile applications. It’s maintenance-free, so no water topping or periodic electrolyte checks are required, and its cycle life can be up to twice that of conventional flooded batteries under similar conditions.

• AGM design: sealed, spill-proof, and vibration resistant
• Maintenance-free: no watering or regular electrolyte checks needed
• Extended cycle life compared with standard lead-acid cells

What safety and quality assurances does Goodyear provide?
