Data Carrier Battery Service Life
V600-D2KR16
With a V600-D8KR04 DC at 55°C (131°F), for example, 200 bytes of data can be
accessed 3,000 times a day for 8 years or 6,500 times a day for 5 years.
With a V600-D8KR12 DC at 55°C (131°F), 40 bytes of data can be accessed
2,000 times a day for 8 years or 4,500 times a day for 5 years.
The battery used for the V600-D2KR16 has a service life of 2 years at an ambi-
ent temperature of 25°C, regardless of the number of access times or R/W
bytes.
The above graph shows the relationship between the service life of a built-in bat-
tery and ambient temperature (after the insulation sheet is removed). The table
below shows the life expectancy of a battery that is stored separately (without
being installed in the DC).

30 2
40 4
50 8
60 16
70 32
If the DC is kept at a temperature of 70°C without removing the insulation sheet,
the battery will last for 1.36 years (2 years x (1 – 0.32)). Furthermore, if the DC is
kept for one year at a temperature of 70°C without removing the insulation sheet,
the battery will last for an additional period of approximately 1.4 years if used at
an ambient temperature of 25°C. The life of the battery will be shorter if used at
an ambient temperature of 0° or 50°C.
Note 1. The data in the V600-D2KR16 will be lost at the time of battery replacement.
Be sure to make a backup of the data before replacing the battery.
2. After replacing the battery, be sure to affix the battery cover seal. IP50 is not
guaranteed if the battery cover seal is not affixed.
