Barden Power Max batteries

Troubadour - thanks for your positive contribution to this posting. I've PM'd you.

Just for the record, according to Wikipedia GELs are VRLA batteries - Valve regulated lead acid. Also see Sonnenschein.org - the original patent for GEL batteries in 1957.

Postings about anchors will always go around in circles because its down to people's often biased opinions - what Troubadour and I are trying to do here is get to the facts. Postings that do not add value are not welcome. If you want to waste you time on pointless internet chat then go to The Lounge or Scuttlebutt.

Based on looking at Sonnenschein's (now part of Exide) gel batteries manual at http://www.sonnenschein.org/PDF files/GelHandbookPart1.pdf I have to concede that gels are apparently now classified as VRLA. They weren't, the term was devised to cover AGMs. Gels do not have many of the characteristics of AGMs in particular they have surplus electrolyte and they don't recombine fully. The Sonnenschein manual confirms that. I don't think they should be called VRLA but no good fighting it, I will adapt my terminology!

I don't accept the Wikipedia page as authoritative. I actually rewrote part of it myself because it was full of factual errors (like claiming Concorde invented the AGM battery in the 1980s). I see someone has now rewritten part of it again and put in complete rubbish like "holding roughly 1.5x the AH capacity of flooded batteries due to purer lead."
