HOBO U30 Station (NRC) User’s Guide
63
Power
The HOBO U30 Station has a 4-volt sealed lead-acid. The battery will start
to run down if it is not recharged. Therefore, the system requires either a
solar panel or an AC adapter plugged in to ensure the battery does not run
too low.
Keep in mind that even rechargeable batteries eventually fail, and will not be
able to be recharged. With regular usage, the battery should last more than
two years. See the next section for details on how to maximize battery life.
Important
:
Due to the self-discharge characteristics of this type of
battery, it is imperative that you charge the battery for at
least 12 hours every six months at minimum, even if you
are not actively using the HOBO U30 Station. Otherwise,
permanent loss of battery capacity may occur.
