[QUOTE="Pete Appleton, post: 4073, member: 145"] [b]Busted Burlen?[/b] Peter Has your Burlen battery really packed up or have you let it go flat and then can't get it to take a charge? You will find that many modern batteries using exotic materiels require a very high initial charging voltage to kick them back into life. I recently revived a 'dead' 6 Volt Burlen but had to start it off with about 15 Volts. It now charges fine from a dynamo and holds charge for weeks. If you are doing this then extreme care is required to limit the current that flows into the battery at these high voltages. A variable current power supply is an ideal way to limit the current to less than 1 Amp. Most people wont have one of these but running a battery charger at 12V and [B]in series[/B] with a 12V bulb should do the trick. Failure to limit the current will result in, at best, a damaged battery and at worst a fire or a face full of bits of battery when it explodes. :eek: It could be safer to find a battery specialist to perform the initial charge for you if electrics are 'not your thing' To hide my horrible modern battery I cut a section from an old inner tube and slid it over it like a sock. Black rubber instead of white plastic seems much better. Pete [/QUOTE]
