8.2.1 Battery Type Selector
The Power Pak is compatible with many types of batteries. The table below shows a list of supported battery
types and associated charge voltages. The battery type can be set by pushing the button to the left of the
LEDs on the front of the Power Pak.
WARNING
Failure to select the correct battery type can result in reduced performance, fire or explosion.
Selecting de-sulphation may result in battery damage, fire or explosion if used improperly.

8.2.2 De-Sulphation
The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you
do not know what you are doing. Before ever attempting to use this cycle you must clearly understand what it
does and when and how you would use it. NOTE: this applies to lead acid batteries only.
What causes sulphation? It can occur with infrequent use of the batteries, or if the batteries have been
discharged so low that they will not accept a charge. This can cause a sulphated crust to form on the
electrode plates inside a lead acid battery, which can inhibit the plates’ ability to accept a charge. This does
not occur in lithium ion batteries, and the de-sulphation cycle should only be used with lead acid batteries.
The de-sulphation cycle applies a very high voltage charge to try to break down the sulphated crust. If
successful this will clean the electrode plates and enable them to once again accept a charge .
