# §111.15-3. Battery categories.

- (a) A battery installation is classified as one of three types, based upon power output of the battery charger, as follows:
  - (1) **Large.** A large battery installation is one connected to a battery charger that has an output of more than 2 kW computed from the highest possible charging current and the rated voltage of the battery installation.
  - (2) **Moderate.** A moderate battery installation is one connected to a battery charger that has an output of between 0.2 kW and 2 kW computed from the highest possible charging current and the rated voltage of the battery installation.
  - (3) **Small.** A small battery installation is one connected to a battery charger that has an output of less than 0.2 kW computed from the highest possible charging current and the rated voltage of the battery installation.
- (b) Batteries that generate less hydrogen under normal charging and discharging conditions than an equivalent category of lead-acid batteries (e.g., sealed batteries) may have their battery category reduced to an equivalent category of lead-acid batteries.
