Charger operation key points

• The only manual setting on the charger is the charge current dial. Use this with the charge current meter to set the correct charge current for your battery.
• The charger detects charge state through either voltage change and/or temperature change
• Batteries can be discharged prior to charging by pressing the discharge button once the battery is connected (see steps below)

The MW7168 battery charger has a number of useful features that make it ideal for charging cycle light batteries, probably the best being that it can charge most batteries faster than they are used. However this needs to done correctly so as not to damage the batteries.

• Use the temperature sensor
• know the mA rating of the battery
• if in doubt charge at a lower rate

• Connect the correct plug fitting to the + and - posts of the charger
• Remove the temperature sensor from the compartment in the charger
• Connect the charger to the power source (car cigarette lighter usually)
• Attach the temperature sensor to the battery firmly Batteries housed in metal(eg nightsticks) etc use of the sensor will be not practical
• connect the battery to the charger, the red charge light should be lit. The charger will now atempt to detect the type of connected battery
• During this process (about 1 minute) the charge lights will flash and the gauge will pulse.
• At this point you will need to adjust the charge current dial so that the gauge reads an appropriate level for the battery connected (see below)
• Charging will commence after this and the charge lights will indicate progress
• Pressing and releasing the discharge button once will cause the charger to commence discharging the battery before starting the charging process Pressing the button again will change back to charge mode
• Once the battery has completed charging the green Ready light will flash

Setting the correct Charge Current

The gauge is graduated in Amps (A) and most batteries capacities are stated in milliamps (mA).

When connecting a battery to the charger you will need to adjust the charge current dial to an appropriate setting for your battery. This needs to be done as soon as possible after connecting the battery.

Table of batteries and suggested charge current settings

In theory you can use a charge rate equal to the mA rating of the battery (eg the 4500 Flat Pack could be charged at 4A) but in practice this can cause excessive heat in some cells, so we have found that a slightly lower rate works best. In most cases batteries are charged in less than 1 hour since they are rarely completely empty.
