Due to the size and type of battery, testing and work procedures vary <br /> between battery jars above and below 100 watts per battery; work procedures may vary by UPS and <br /> battery type and may be limited by safety requirements. All additional work will be billable at the <br /> applicable rates per Attachment X-1. <br /> Below <br /> Performed During Each Preventive Maintenance Visit': 100W/Jar 100W+/Jar <br /> A. Measure and Record the following: <br /> 1. Individual cell/battery float voltages and overall float voltage Yes Yes <br /> 2. Charger output current and voltage Yes Yes <br /> 3. AC ripple current and voltage imposed on the battery Yes Yes <br /> 4. Internal ohmic values of each cell/battery or perform a continuity No Yes <br /> test of each cell/battery <br /> 5. Connection Resistance of 100% of the inter cell/battery connection No Yes <br /> 6. Ambient temperature and ventilation status Yes Yes <br /> 7. Negative terminal temperature of all cells/batteries No Yes <br /> B. Visually inspect conditions and appearance of the following: <br /> 1.
