its an esab origo. I changed the batteries about 3 years ago and it worked since. It has stopped today and the batteries read 2.85v each. Is this high enough? Its also possible one battery is feeding through to the other giving both the same voltage.
Yes, very possible. My Esab Warrior was reading 1.43v on a single 3v battery. The replacement reads 3.33v.
My batteries are not rechargeable but try this link https://www.ebay.co.uk/itm/1-x-3-6V...909325?hash=item2cd4551f0d:g:UD8AAOSw7pleyoai
