What is the IEC/EN Guide to Valve Regulated Lead-acid batteries?

This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the ‘user’ with guidance in the preparation of a Purchasing Specification.

What happens when a lead acid battery is discharged?

The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs.

Why are VRLA batteries acid-starved?

Our VRLA batteries are designed to be “acid-starved.” This means that the power (sulfate) in the acid is used before the power in the plates. This design protects the plates from ultra-deep discharges. Ultra-deep discharging is what causes life-shortening plate shedding and accelerated positive grid corrosion which can destroy a battery.

Is lead-acid battery a target product for SDS (safety data sheet)?

Lead-acid battery is not a target product for SDS (safety data sheet). This sheet is intended to be issued in order to provide "reference information" to ensure the safe handling of the product. 2. Hazards Identification 3. Composition/Information on Ingredients NO. 4. First-aid Measures

How do you calculate the residual capacity of a lead-acid battery?

For every 10°C increase in the temperature, the self-discharge rate doubles. In traditional open lead-acid batteries with filling caps, where free acid is used, it is possible to estimate the residual capacity of the battery by measuring the density of the acid.

Why are VRLA batteries protected against deep discharge?

• Our VRLA batteries are protected against deep discharge because they are “acid-starved.” This means that the battery uses the power in the acid before it uses the power in the plates. Therefore, the plates are never subjected to destructive ultra-deep discharges. never runs out of water.

Ventilation of battery rooms or cabinets shall be in accordance with with National Regulation and/or IEC/EN 62485-2. Internal resistance can be important to the equipment design and operation.

Battery Glossary – Valve Regulated Lead Acid Battery

To ensure that this does not lead to an explosion the batteries have valves which allow gases under pressure to escape – hence the term ''Valve Regulated''. The sealed nature of VRLA batteries means many are termed ''maintenance free'' but as this also sometimes appears on flooded lead acid batteries it should not be assumed all maintenance free products are VRLA.

Exploding lead acid batteries

2.1 Valve regulated lead acid (VRLA) batteries (also called ''sealed'' or ''maintenance free'' batteries) There are two primary types; gel cells (with silica dust) and absorbed glass matt (AGM), with the glass or gel used to immobilise the electrolyte. In VRLA batteries the casing is a sealed, more modern design.
