RFL100 Batteries

Main Batteries
RFL100 Data Logger is powered by two AA size primary (non-chargeable) batteries with 1.5 V
nominal voltage. Operation of the data logger always requires that compatible batteries with
sufficient voltage (minimum 2.6 V in series) are in place. When replacing batteries, always use
new batteries, not partially discharged ones. Compatible battery types are:
• 1.5 V alkaline batteries, designation IEC-LR6, ANSI 15A. Standard choice for most
applications.
• 1.5 V lithium batteries, designation IEC-FR14505 (FR6), ANSI 15-LF. Typically higher
capacity, better in cold temperatures.
CAUTION!
Use of rechargeable batteries is not recommended. RFL100 will not charge
batteries even if the service port is connected to a power supply.
Clock Battery
RFL100 also has a separate 3 V lithium battery (type CR1/3N button cell) to keep the real-time
clock powered when the device is otherwise turned off. This battery is good for 10 years, and
should only be replaced if the data logger gives the low clock battery error.
