Are spiral cell batteries good for boat engines?

Boats and marine equipment need batteries that can withstand harsh conditions and frequent vibrations. Spiral cell batteries’ leak-proof design and strong structure make them ideal for this environment. Plus, their ability to deliver high power in short bursts is perfect for starting boat engines.

What is a spiral-wound battery?

The spiral-wound construction gives the battery a cylindrical cell, similar to a common flashlight battery. This design stands in stark contrast to traditional flat-plate batteries that have a rectangular grid of lead plates. The electrolyte in these batteries is absorbed by the AGM, giving these batteries their ‘starved electrolyte’ condition.

How does a spiral cell battery work?

In a spiral cell battery, two lead plates – one positive and one negative – are wound in a tight spiral design. These spirals are separated by an absorbent glass mat (AGM). This mat is made from very thin glass fibers woven into a mat, which increases surface area to hold sufficient electrolytes on the cells and for the chemical reaction.
