Batteries
Leisure/Deep Cycle batteries are specifically
designed for good performance in terms of
charge/discharge cycles. Batteries are the most
important part of your battery charging system
and should be sized according to your load
requirements and provide at least 3 days
reserve capacity. This will reduce cycling,
prolong the life of the battery and ensure
system reliability during periods of low wind.
Permanent connections should always be made
to the battery terminals. Never use crocodile
clips or similar devices.
We strongly recommend that one of the voltage
regulators available from Marlec is fitted to
prevent batteries becoming overcharged in
strong winds and is essential with gel/sealed
batteries.
Batteries may be linked as shown in the figures
10 and 11. It is essential to observe polarity as
follows:
Red is + Positive
Black is - Negative

Further System Requirements
The cable used for connection of the
Windcharger to the batteries should be in
accordance with table 1. The use of a
smaller cable than recommended will
reduce the performance of the charging
system.
Cable and connectors are available from
your dealer or the manufacturer.
