Spiral lead acid battery

What is a spiral battery?

Spiral batteries, also known as VRLA (Valve Regulated Lead-Acid) batteries, are a type of sealed lead-acid battery that uses a spiral design to increase the surface area of the electrodes. This design allows for a higher energy density than traditional lead-acid batteries, making them a good choice for applications where space is limited.

Are spiral batteries worth it?

Additionally, they tend to be more expensive than other types of batteries, making them a less attractive option for those on a tight budget. Spiral batteries, also known as VRLA (Valve Regulated Lead-Acid) batteries, are a type of sealed lead-acid battery that uses a spiral design to increase the surface area of the electrodes.

How to charge a spiral cell battery?

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.

How long does a lead acid battery take to charge?

All lead–acid batteries, irrespective of type, are quick to bulk charge to about 70% of capacity during which the battery will accept a large current input, determined at a voltage setpoint, within a few hours (with a charge source capable of supplying the design C-rate bulk stage current for a given Ah battery).

What are the advantages of spiral cell batteries?

Compared to traditional flat plate lead-acid batteries, spiral cell batteries offer several advantages. First, they are more resistant to vibration and shock, making them durable and long-lasting. Secondly, they can provide higher power outputs for their size due to the increased surface area of the lead plates.

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.
