ignition key has to be on in order for the 12V outlet to supply / receive power, turn the
key, without starting the engine.
8) A marine (boat) battery must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use.
CHARGING MODES
CT1AMBCM has two modes: 12V and 6V. Do not operate the charger until you confirm the
appropriate charge mode for your battery.

NOTICE: Make sure your battery to be charged / maintained is in good condition. The
CT1AMBCM cannot be used to recover severely discharged batteries or dead batteries.
How to deal with the batteries which are deeply discharged, but in good condition?
1. Make sure the battery is in good condition (not dead) and was deeply discharged only.
You can use the battery analyser to get the result if you have.
2. Jumpstart your vehicle or use a battery charger with recovery function to activate the
battery until the battery voltage increases to normal condition. For 12V batteries, the
normal voltage is above 8V at least; for 6V batteries, the normal voltage is above 4 volt at
least.
3. Use the CT1AMBCM Charger / Maintainer do the rest charging and maintaining work.
CHARGING TIME
Different battery capacity and residual voltage would affect the charging time. Following
data is only for reference (when discharge 12V lead-acid battery to 9V, with 5A discharge
current).
