8Caring for the Battery
The life of the nickel-metal hydride battery used in the cardiograph varies by how
the battery is maintained and how much it is used. A depleted battery requires 4
hours of continuous charge to full capacity. If the battery has been fully charged and
requires recharging after a few ECGs, consider replacing it. Use only Agilent
battery, part number M3941A/M3951A.
Be sure to use only the cardiograph to charge the battery and never
disassemble the battery. Failure to do so may cause excessive current,
leakage, overheating, rupture, or fire.
Do not charge or use the battery with the positive and negative terminals
reversed. Doing so may discharge the battery, or causes excessive current,
leakage, overheating, rupture, or fire.
Wash eyes with clean water and see medical treatment immediately in case
of electrolyte entering into eyes.
Keep water out of battery pack.
Be sure to use and charge the battery within a temperature of 0 to 40 °C. Charging or
use below 0°C or above 40°C may cause leakage or overheating, or shorten the
battery life.
