I'm a happy Ikelite user from 10 years ago. Housings, ports, and strobes.
My last change, one year ago, was moving to the Li-Ion batteries and chargers. Very happy, less weight, less space and more performance.
Well... my problem is that, suddenly, I can't charge two of my three batteries. Just the charger stay flashing all the time. Never stop and don't charge. I've two Li-Ion chargers and therr batteries and tryed a lot of combinations...
I found this:
The center contact of the receptacle into which you plug the charger has a split pin that can get squeezed together preventing good electrical continuity. Take something like a small screwdriver and spread the center pin slightly so it provides a snug fit with the plug. The socket is diode protected to only allow electricity "in" so you do not need to worry about a short circuit if you touch the side of the socket.
But don't solve my problem.
I found an article about Li-Ion explanng that this batteries can protect the circuit and "sleep" until a smart charger wake up again the battery.
I googled a lot and can't find the solution. I know, I've the Ikelite support but I'm almost sure is not a manufacturer problem, something strange with the charging process.
Thanks in advance.
