Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration. Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building.
It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
The legal requirements for lead-acid batteries in relation to “end of useful life” are such that they should be disposed in a manner that is appropriate to the current laws and regulations within the state. The storage of the batteries has to be such that it conforms to the safety rules and regulations.
Disconnect charging source and load before connecting or disconnecting terminals. Vented lead-acid (VLA) batteries can contain an explosive mixture of hydrogen gas. Do not smoke, cause a flame or spark in the immediate area of the batteries. This includes static electricity from the body and other items that may come in contact with the battery.
Abstract: Recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, preassembly, assembly, and charging of vented lead-acid batteries are provided. Required safety practices are also included. These recommended practices are applicable to all stationary applications.
