Replacing a Storwize V7000 Gen2 CMOS battery
The complementary metal-oxide semiconductor (CMOS) battery is a coin-shaped
power cell that is mounted inside a node canister. It is used to keep the system
time when there is no power to the node canister. The lithium battery must be
handled correctly to avoid possible danger. If you replace the battery, you must
adhere to all safety instructions.
About this task

properly.
CAUTION: If your system has a module containing a lithium battery, replace it
only with the same module type made by the same manufacturer. The battery
contains lithium and can explode if not properly used, handled, or disposed of.
Do not:
v Throw or immerse into water
v Heat to more than 100°C (212°F)
v Repair or disassemble
Dispose of the battery as required by local ordinances or regulations. (C045)
