This is a kit to provide a small current to the control panel on your Alde system. Especially useful when your model is in storage. Requires 2 x AA batteries (not supplied)
Easy to fit, connecting to small 2-pin plug in the back of the panel, 
A very useful accessory, don't risk your control panel not coming back to life after a period with no power at all. A new panel is over £200
Please note, this has thinner wires so the batteries last longer, and the kit comes with self adhesive velcro,   The wires are 25cm long.
