BATTERY SYSTEM
BATTERY REPLACEMENT
When replacing batteries in a machine it is important to replace them with quality batteries
that are designed for high-output deep-cycle applications, such as the ones furnished by
the factory when the machine was new. All batteries are NOT created equal. In the event
you are considering other manufactures batteries make sure to compare their 75 AMP
RESERVE CAPACITY. That is the ONLY specification that corresponds to the usage the
batteries will be seeing.
When a battery fails in the first 12 months of operation replacing a single battery may be
acceptable if the failure was caused do to manufacturing defect. If the battery pack is older
than 12 months or the battery has failed due to neglect the entire battery pack should be
replaced as the batteries operate as a system.
When replacing batteries it is important to neutralize any battery acid that is in or on the
machine after battery removal. Clean and dry the machine after neutralization and removal
of any acid. The batteries should be installed in a clean and dry machine.
When installing batteries a terminal protectant should be used to help inhibit battery termi-
nal corrosion. It is important to use a product specifically designed for this and not things
like grease, silicone or paint. Read and follow the directions on the can of protectant ex-
actly to prevent terminal or cable failure.
BATTERY CHARGER
The standard charger supplied with the MiniMAG is an on-board fully automatic charger.
To operate the charger all that needs to be done is plug in the charger cord into a wall outlet
of the proper voltage. The charger will run until the batteries are fully charged and then
automatically shut off. It is important to let the charger finish its charge cycle before discon-
necting it as the last few hours of a charge cycle are very important.
The charger has a digital readout that scrolls the charging information across it as well as
displays fault codes in the event there is a failure with the charger.
DRY SHIPPED BATTERIES
Overseas users will usually receive units from us equipped with dry batteries. These are, in fact,
wet batteries that had their acid removed at the factory. The technical term is “damp” battery. The
cells are sealed with tape.
These batteries should come with instructions on how to charge them.
These batteries should not be stored for a long period of time. They must be filled and charged
within six months of their date of manufacture.
To prepare the batteries, you will fill the batteries with a mixture of dilute sulfuric acid. This Can nor-
mally be purchased premixed from your local battery supplier. Fill the battery with a solution so the
plates are covered but so that the electrolyte (acid) does not reach the “ring” inside the battery. The
batteries should be charged for about 24 hours on a low slow charge after this..
