The Basics

NOTE
z Life expectancy of a battery depends on how frequent and how long it is
used. For a properly maintained and stored lead-acid or lithium ion
battery, its life expectancy is about 2 or 3 years respectively. For more
aggressive use models, life expectancy can be less. We recommend
replacing lead acid batteries every 2 years and lithium ion batteries
every 3 years.
z The battery might be damaged or malfunctioned if its operating time is
too short after being fully charged. The operating time depends on the
configuration and operation. For example, measuring NIBP more
frequently will also shorten the operating time.
2.5.2 Battery Recycling
When a battery has visual signs of damage, or no longer holds a charge, it should be
replaced. Remove the old battery from the monitor and recycle it properly. To
dispose of the batteries, follow local laws for proper disposal.
WARNING
z Do not disassemble batteries, or dispose of them in fire, or cause them
to short circuit. They may ignite, explode, leak or heat up, causing
personal injury.
