Valve-regulated lead acid, or VRLA, batteries are sealed batteries without caps that open on each cell. The electrolyte solution inside of the battery has a gel in it to keep the fluid thick. This type of battery is used in golf carts, wheelchairs and scooters to minimise the risk of acid spilling out when the vehicle tilts or turns over. VRLA batteries are rechargeable and require a specific battery charger. Items that use VRLA batteries for their power usually include a charger for them with the purchase.

Tips and warnings
- Devices that use VRLA batteries and are in use daily should be charged each night. The battery takes approximately eight hours to charge fully.
- Do not use a VRLA battery charger on VRLA batteries for acid batteries such as car batteries. The VRLA charger supplies electricity at a much lower rate than a traditional battery charger.
