I bought one of these and when I got it switched on the red charging led came on then went out fairly quickly and the green came on. I turned the lamp on overnight to see how long it would lastand it was out by morning.
I put it on charge again but the green led came on immediately. Pulled it down to have a look and the solder on the board was pretty bad . Removed a loose bit trapped under a screw and cleaned it up generally but when reassembled only the green came on even though the battery was flat.
So returned it and got another which looked good when plugged in , the red led came on but I found the green led does not appear to come on . Cleaned this shocker of a board up and removed some loose solder too but it still hasn't turned green yet .
So I've been looking at the rechargeable 6 Volt sealed lead acid batteries supplied and they are called "valved regulated rechargeable battery -constant voltage charge"
I firstly wondered what that meant and where I might see a typical circuit for the "valve". I assume the valve restricts charging current as I left one of them on for a few hours at 1 Amp charge and when I came back it had closed up and was not taking any current at all.
Its a LT640 XINSHUN Chinese 4.0 amp hour battery so I charged it at 400mA and I find it is gassing at about 7V and the notes on the side say "cyclic use 7.25-7.45V, standby use 6.8-6.9V"
So I have the battery charged to 7.3V odd and the red led is still not off so I think Ill take this one back also
Does anybody know anything about the battery or the lantern. It seems it might be a good useable product if I can get the battery charging /discharging as intended?
