How often should I change the backup battery?
When using the backup battery there is an indicator that flashes when the battery is getting low. The typical life of the battery in these units is 5 years, but the battery should be checked every six months.
- D2-230 and D2-240 use the D2-BAT
- D2-250(-1), D2-260, and D2-262 use the D2-BAT-1
The D2-BAT-1 is a Panasonic CR2354, which can be found locally, if needed. It does have to be a "Panasonic" type, if you look at the battery profile, it kind of looks like a top hat. If it has straight sides, that will not work.
We have been made aware that there are some generic "CR2354" batteries that look like the Panasonic type (top hat style) but are 0.06" (1.5mm) taller then the Panasonic specification. If the battery doesn't easily insert into the holder, do not force it, you will break the PLC battery holder. Please make sure that the battery that you have is "Panasonic" or follows the Panasonic specifications.
