Guarantee certificate
Please study these instructions, reading them completely and attentively, before using
the unit for the first time. This will guarantee that you will be able to exploit all the
facilities of your new battery charger. The warnings and safety notes are particularly
important. Please store these instructions in a safe place, and be sure to pass them on
to the new owner if you ever dispose of the charger.
In the ULTRAMAT 17 you have acquired a mature product with an excellent performance. It
incorporates the latest semi-conductor technology, controlled by a high-performance RISC
micro-processor, to provide superior charging characteristics combined with simple operation
and optimum reliability. These features can normally be expected only from much more expensi-
ve units. The ULTRAMAT 17 represents a reliable method of charging sintered Nickel-Cadmium
(NC, Ni-Cd) packs, Nickel-Metal-Hydride (Ni-MH) batteries, Lithium-Polymer (Li-Po), Lithium-
Manganese (Li-Mn) , Lithium-Ion (Li-Io) and LiFePO
acid (Plumbum: Pb) batteries These sealed, gas-tight batteries have proved excellent for our
purposes in RC models. They are mechanically robust, can be used in any attitude and are
generally highly reliable. They require no special measures for storage apart from protecting the
cells from becoming deep-discharged. The ULTRAMAT 17 can also be used to discharge your
batteries and balance the cells in a pack.
Note
It is important always to observe the charging instructions supplied by the battery manufacturer,
and to keep to the recommended charge currents and times Do not fast-charge batteries unless
the manufacturer states expressly that they are suitable for the high currents which flow during
these processes. Please bear in mind that new batteries do not reach their full capacity until they
have been charged and discharged several times. When charging new batteries you may also
encounter problems with premature charge termination. Whenever you wish to use a new
battery it therefore makes sense to carry out a series of monitored test charges, so that you
can check that the automatic charge termination circuit works correctly and reliably with your
packs, and charges them to full capacity.
