Maintenance
Batteries
The internal battery pack in the Rover holds 18 AA batteries. There is no provision for external
power.
Choosing Batteries
While the battery pack can hold and operate with any AA battery, some battery models might
experience failure and are not recommended for use. Duracell batteries should not be used since
the seal is more apt to fail and cause leakage in higher temperature conditions.
1. Xeos recommends the Energizer EN91 AA alkaline battery, or the Energizer L91 Lithium
battery.
Do not mix battery types.
2. All new batteries should be used for each new deployment.
3. Each battery should be tested with a battery tester or voltmeter to ensure none of the
cells are defective or discharged. Individual cells with a voltage measuring less than 1.5 V
should be discarded.
When not in use, the Rover should not have batteries installed.
Adding/Replacing Batteries
The batteries are configured in 6 columns of
3 batteries each.
Each column is labelled to show the correct
orientation the batteries should be installed.
Take care to orient the batteries the correct
way as the columns alternate direction.
Incorrect battery installation will activate
the self-test failure mechanism.
The battery pack column is magnetized to ensure the batteries stay in place properly.
To add/replace batteries:
Open the housing
Remove old batteries by pulling the bottom batteries from the springs, and sliding the
rest down with a single shake.
Slide the new batteries into each column with respect to its labelling for correct
orientation
The Rover may beep to indicate changes in the battery voltage as it can start as final batteries
are installed.
Once all the batteries have been replaced, the Rover will stop beeping. The enclosure pieces can
be reassembled, taking care to inspect and seat the O-Rings first.
