Each Intel® Server Board carries a coin battery to preserve the Complimentary Metal Oxide Semiconductor (CMOS) memory data during power absence.
Intel server appliances are considered as equipment containing lithium batteries because of the coin battery contained in the motherboard. Some customers require customs certification to import these devices.
Intel® Server Boards use the commonly known CR2032 batteries in all its models.
- Some countries (that is, China, Korea) require declaration and specifications of chemical containing parts such as batteries.
- These batteries are not RMAd by Intel so it might be necessary to buy them from a third party whenever they need to be replaced.
The memory battery (also know as motherboard, CMOS, real-time clock (RTC), clock battery) is generally a CR2032 lithium coin cell. This cell battery has an estimated life of 3 years when the power supply unit (PSU) is unplugged or when the PSU power switch is turned off.
This battery type is not rechargeable and trying to do so may result in an explosion. Motherboards have schematics preventing batteries from being charged and discharged when a motherboard is powered on. Higher temperatures and longer power-off time will shorten battery cell life.
When replacing the battery cell, the system time and CMOS BIOS settings may revert to default values. Unwanted BIOS reset may be avoided by replacing the battery cell with the PSU power switch turned on and plugged into an electric socket on the wall. On ATX motherboards, turning on the power switch on the PSU will supply 5V standby power to the motherboard to keep CMOS memory energized during computer turned off period.
