They are not under constant charge.
Both are showing 12.9V on the screen and zero Amps.
But if the volts fall below 12.6 it will begin a trickle charge.
Do some homework.
From the instructions:
5. MAINTAIN ( FLOAT CHARGE ):
a. The Oximiser 900 will maintain and optimise the battery indefinitely so long as it
remains connected to the battery.
b. Continual voltage monitoring determines the battery condition and charge rate
i. At 14.4Volts the charging is automatically stopped
ii. If the battery voltage drops below 12.6V it will apply the necessary charge rate to
ensure the battery remains in perfect condition. The Oximiser 900 will apply
a gentle charge up-to 200mA/h to ensure the battery is brought up to a full charge.
iii. If the battery remains in optimum condition, the Oximiser 900 will not attempt to
charge the battery, therefore no over-charging can occur.
c. In this mode the battery “on-charge” indicator will not be shown.
