CTEK MULTI US 7002 Mode D'emploi page 7

Caution: If the MULTI US 7002 does not switch to maintenance charge mode after three
days, manually switch it to pulse maintenance mode.
Note: A battery that hasn't changed to maintenance charge after three days is most likely
worn out and needs to be replaced. All other batteries can be maintained for a very long
time.
BATTERY TYPES AND SETTINGS
MULTI US 7002 can easily be set for different types of batteries or conditions. The follow-
ing recommendations should, however, only be seen as guidelines. Please consult the
battery manufacturer for further instructions.
Settings are made by pressing the "MODE-button" and stepping forward one press at a
time until the required mode is reached, the button is then released. After about 2 seconds
the charger activates the selected mode. The selected mode is saved in a memory in the
charger and remains there even if the charger is switched off.
Mode 14.4V - Normal setting for wet batteries, maintenance free and for
NORMAL most Gel batteries. Some Gel batteries prefer a slightly lower charging volt-
age. Please consult the battery manufacturer when in doubt.
Mode 14.7V - This setting is recommended for a battery at temperatures
< 41°F. It is also recommended for many AGM batteries like Optima, and
Odysseys. Consult your battery manufacturer when in doubt.
Mode 13.6V / Supply - The charger is operating at a constant voltage of
SUPPLY
13.6V. This is the maintenance mode for applications where maximum ca-
pacity from the battery is important, like floor sweepers and golf carts. Note
that the Spark protection function is suppressed in this mode.
Mode 15.7V / 1.5A / 0.5–4h - This mode is used to recover deep discharged
flooded batteries where you could expect a stratified acid (high acid weight
in the bottom, low on top). This mode will also recover some spiral cell AGM
batteries that has been deep cycled. Check with battery manufacturer when
in doubt.
RECOND
Note that the battery has to be fully charged first. Use this mode with care,
because the high voltage will cause some water loss. 16V is normally no
problem for electronics, but consult your supplier when in doubt. Life of light
bulbs will be reduced at higher voltage. Try to avoid using 12V light from the
battery during this phase. Maximum effect and minimum risk for electronics
is achieved by charging a disconnected battery.
