CSA C381.2-17 Energy performance of battery-charging systems and uninterruptible power supplies. 5 Test procedure for battery chargers other than UPS 5.1 General setup The general set up of the battery charging system shall meet the following requirements: a) The battery-charging system shall be prepared and set up in accordance with the manufacturer’s instructions, except where those instructions conflict with the requirements of this test procedure. If no instructions are given, then factory or “default” settings shall be used, or where there are no indications of such settings, the UUT shall be tested in the condition as it would be supplied to an end user. b) If the battery charger has user controls to select from two or more charge rates (such as regular or fast charge) or different charge currents, the test shall be conducted at the fastest charge rate that is recommended by the manufacturer for everyday use, or, failing any explicit recommendation, the factory default charge rate. If the charger has user controls for selecting special charge cycles that are recommended only for occasional use to preserve battery health, such as equalization charge, removing memory, or battery conditioning, these modes are not required to be tested. The settings of the controls shall be listed in the report for each test. 5.2 Selection and treatment of the battery charger The UUT, including the battery charger and its associated battery, shall be new products of the type and condition that would be sold to a customer. If the battery is lead-acid chemistry and the battery is to be stored for more than 24 h between its initial acquisition and testing, the battery shall be charged before such storage. Note: UUTs using inductive connections may be tested in accordance with this Standard. 5.3 Selection of batteries to use for testing The selection of batteries to use for testing shall meet the following requirements: a) For chargers with integral batteries, the battery packaged with the charger shall be used for testing. b) For chargers with detachable batteries, the battery or batteries to be used for testing will vary depending on whether there are any batteries packaged with the battery charger as follows: i) If batteries are packaged with the charger, batteries for testing shall be selected from the batteries packaged with the battery charger, according to the procedure in Clause 5.3 c). ii) If no batteries are packaged with the charger, but...
