The RTC uses a Lithium cell battery (CR1225). We choose to use the RTC based on DS1307 as it is low cost and also very energy efficient. It can run for years on a very small coin cell!\u003c\/p\u003e\n\u003cp\u003eThe clock\/calendar provides seconds, minutes, hours, day, date, month and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year.
