      No matter which technology one prefers, lead-acid still is the most attractive in terms of energy yield to price value. Most buyers of this technology should also know that it’s not uncommon for the rebated faulty to be recycled at an extraordinary rate of over 90%. It would be great if manufacturers can start supplying just the cells at a non rip off rate so users can replace just the dead cell. A very nice image of the lead acid battery cutaway can be found here under how it works: http://www.howitworksdaily.com/inside-car-batteries/

      The most reliable batteries are lead-acid traction (fork-lift, deep cycle) and NiFe. They are expensive, traction batteries are usually sold per cell – this also makes them more cost effective in the long run. They do require more maintenance however. I believe marine batteries these days are all AGM, to prevent spillage and therefore damage to yourself and electronic equipment.

      @Gravytrain: I have no doubt that spilt electrolyte will damage the mariners as well as onboard electronics – it will eat into practically anything that is not plastic or gold. An important lesson learnt in the world wars was that the combination of electrolyte and seawater or brine will generate a healthy flow of chlorine gas which lead to the loss of life of many submariners. Chlorine gas is not to be trifled with – in high or prolonged doses it will kill you permanently. On smaller marine classes this may may not be a biggie, on submarines definitely. I stand under correction but lead-acid batteries also add to the stability properties because of their size and weight. I have been on a few 2nd WW subs, luckily never out to sea.
