In general, spiral cell batteries are a great choice for applications requiring above normal power output, quick recharging, and a robust, maintenance-free design. When it comes to charging, spiral cell batteries require a specific approach. They need a higher voltage compared to regular lead-acid batteries.
Spiral cell batteries have a wide range of applications due to their robustness, high power density, and maintenance-free design. Here are some areas where they are used: Automotive industry. Spiral cell batteries are ideal for vehicles that require high starting power.
When it comes to charging, spiral cell batteries require a specific approach. They need a higher voltage compared to regular lead-acid batteries. Also, they should not be overcharged as this can lead to excessive heat and damage the battery. It’s recommended to use a charger designed specifically for use on AGM batteries.
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.
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.
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.
