The Warning Battery Charging 7523 sign will be used to inform people of this fact. People may not have been aware of this charging, if they had not seen the sign displayed, and this could potentially lead to problems.

It is a good idea to make sure that you display this sign in a position that will be visible to all people concerned. As an extra bonus feature, it will even glow in the dark when there is a lack of lighting, as it is Jalite AAA photoluminescent.

Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
