Ticket Question[Replacement]

[Secware]

The 6 stand-by batteries in the main panel are not being trickle charged. Replacing them with fully charged new ones (1.37V) gets the system working correctly in all respects but only for approx 3 hours. The cells are then down to 1.2V off-load.
Have you any information regarding the charging circuit that could allow me to investigate further and possibly repair?
Your website indicates that the Homelink 75 is “sold out”. If I need to purchase a replacement system can you please recommend a suitable model

 

Having had further time to think, it would seem logical to assume that the panel’s internal power supply is not producing anything at all - not just the battery charging voltage.
Putting new fully charged batteries in runs the system correctly until the batteries run down.
Is it possible to obtain a replacement power supply board?
