CAUTION:
When replacing the lithium battery, use only Lenovo Part Number 33F8354 or an equivalent type
battery recommended by the manufacturer. 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:
– Throw or immerse into water
– Heat to more than 100°C (212°F)
– Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.
To remove the system battery, complete the following steps:
Step 1.
Remove the compute node (see “Removing a compute node from a chassis” on page 77).
Step 2.
If necessary, lift the node and SATA cable out of the way (see “Removing the node SATA cable” on
page 148).
Step 3.
Remove the system battery:
a.
Use a fingernail to press the top of the battery clip away from the battery. The battery pops up
when it is released.
b.
Use your thumb and index finger to lift the battery from the socket.

Attention:
Do not lift the battery by using excessive force. Failing to remove the battery
properly may damage the socket on the system board. Any damage to the socket may require
replacing the system board.
Step 4.
Dispose of the battery as required by local ordinances or regulations.
Replacing the system battery
Before you install the system battery, complete the following steps:
1. Read the safety information in “Safety” on page v and “Installation guidelines” on page 75.
2. If the compute node is installed in a Lenovo ThinkServer n400 Enclosure Type 5495, remove it (see
“Removing a compute node from a chassis” on page 77 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
The following notes describe information that you must consider when replacing the system battery in
