Backup Battery
After the spring of 2015, new McLane CF2-based instruments no longer require a backup battery.
Prior to this change, the backup batteries served as a voltage source for the electronics while in low
power sleep mode. Electronics hardware changes made the backup battery unnecessary, and it was
eliminated.
If using an older Sediment Trap, check for backup batteries. If your system has backup batteries,
be sure to replace them before each deployment. On the TT8 microcontroller based devices, the
backup battery was a 9 volt battery mounted beside the electronics. On the Persistor CF2
microcontroller based devices, the backup battery was two AAA batteries mounted near the
electronics.
