What type of data must be included in installation documentation regarding batteries?

The inclusion of battery group data in installation documentation is crucial because this data provides specific information about the type and size of the battery, as defined by industry standards. Battery group data indicates the physical and electrical characteristics of the battery, such as its dimensions, terminal configurations, and capacity ratings. This information is essential for ensuring that the selected battery is compatible with the electrical system and that it fits properly in the designated space. Furthermore, it helps in identifying the battery's ability to deliver the necessary power for the application's requirements.

While estimates of battery lifespan, costs, and warranty information can be relevant in different contexts, they do not carry the same level of importance for installation documentation. Battery lifespan estimates can vary based on usage and conditions, costs can change over time, and warranty information pertains to manufacturer guarantees rather than installation requirements. In contrast, battery group data is a fundamental aspect that directly influences the safety, performance, and compliance of the electrical installation.
