Charges in 45 minutes, guaranteed for 3 years, greener than other batteries as no component is toxic unless you eat it presumably, 80% lighter weight and will power your golf trolley around 18 holes for 2000 hours! I reckon with lightweight trap use this will last me a long time plus it replaces a 27amp lead acid battery so will last more than one night even in winter with a 15w lamp.
All the technical details about lithium batteries are in Wikipedia plus the supplier: Alpha batteries has a comprehensive website.
Cost? Cheaper than a posh frock (not that I'm in danger of buying one of those), or lunch for 2 at Ynys Hir Hall (not that I've been invited yet) or 2 fills of diesel in the VW. I just heard Evan hit the floor….
If I don't catch some moths with it tomorrow then you'll hear me hit the floor.
