Essential Safety Guidelines for Handling Valve-Regulated Lead Acid (VRLA) Batteries

When handling VRLA batteries, safety is crucial. Although these batteries are widely used for their ‘sealed’, maintenance-free design, they still carry potential hazards if not managed correctly. It’s important for anyone working with or around these batteries to understand proper handling and safety practices to prevent injury and ensure the batteries function as intended. 

In Valen’s AGM (Absorbent Glass Mat), Gel and Hybrid batteries the electrolyte is immobilised, meaning these batteries can be handled and shipped like dry materials. 

These lead-acid batteries are encased in durable ABS plastic. While tough, if the casing is compromised, lead and sulphuric acid can be exposed, posing health risks. 

Sulphuric Acid Hazard 

If it contacts skin or eyes, flush the area with water and seek medical help immediately. Burns and serious injuries can occur. 

In the event of an acid spill, apply a layer of baking soda on the spill area.  Avoid using cleaners or solvents on the battery. 

Safety First  

1. Always disconnect power before handling, installing, or servicing the battery. 

2. Do not tamper with the battery’s casing, vents, or terminals. Although known as ‘Sealed Lead Acid’ batteries, they are not completely sealed. These Valve Regulated Lead Acid (VRLA) batteries have hidden valves to vent gas under a plastic cover. 

3. Keep batteries clean and dry. Moisture can accelerate discharge and cause malfunction. Excess dust or debris around the battery can also affect performance. 

4. Ensure battery connections are clean, greased, and tight. Loose connections may reduce standby time or even cause a fire. 

5. Handle damaged or dropped batteries only with proper PPE, including rubber gloves and face protection. 

6. Never disassemble a battery. 

7. Batteries release small amounts of hydrogen gas through their valves, which can ignite in confined spaces. Never charge or use batteries in airtight containers. 

8. Keep all ignition sources, including cigarettes, away from batteries. 

9. Avoid contact between battery terminals and metallic objects, as even small batteries can cause short circuits and serious injury or fire. Remove loose items such as long necklaces or bracelets that could fall onto terminals.  

10. Follow proper lifting techniques and ensure compliance with Workplace Health and Safety regulations. If the battery is too heavy, contact Valen for suitable lifting equipment.
