Great article and proves what I have always thought - basically batteries are no better now than they have always been.

They still use normal lead acids in trains and submarines which says it all.

Of course having a sealed battery that can go upside down is great and possibly of use in a RIB but most yacht batteries are normal wet cells such as Rolls and they cope being heeled over a lot for days on end!!!

Yep, we always used to say that when i worked on big traction batteries,
battery technology had progresses very little in 100 years, and the way to tell a good quality cell from a cheap one was by weight.
Traction batteries when looked after generally last very well, but its usually corrosion to the + bus bars that killed them totally, the thicker the lead the longer thay last.
This is my theory why modern car batteries seem to fail suddenly where as years ago they would limp along for months with trickle charging and batt-aid tablets, the lead in the busbars is so thin the final start blows it like a fuse, then its completley dead, long befor the plates start to decay.
anyone else noticed this or just me??

I've noticed it a lot with bike batteries. I have trouble getting them to last more than 2 years.

Watch the term leisure / deep cycle as it simply does not exist. The standard, so called, leisure batteries, are simply starter batteries with extra support for the active lead material. This may increase the life by 5 10 %, but does not turn a starter battery into a deep cycle battery. True traction (deep cycle) are not available at a sensible price and are uneconomical to use for standard leisure use.
So... Let me get this straight: Deep Cycle Batteries don't exist, but they're too expensive when they do?

Am i understanding?....

Rather than get an expensive marine battery i'd be as well going to halfords and getting as high an amp battery as possible for as few 's as possible??

I dont plan on putting my boat upside down and if i did a leaking battery is probably the least of my worries....

Well, A decent battery suppliers-not Halfords... Their 'high amperage' batteries are so light I can throw them quite a distance with one hand.

Well.....when we bought Sixy's car the battery that was in it was the 'recommended' battery from Halfords. It was so light it could have been mistaken for a dummy battery.
