ALKALI MANGANESE

any one any experience or knowledge of this chemistry 1.5V rechargeable 25-100 times http://www.ebay.co.uk/itm/4-X-ACCUCELL-AA-RAM-RECHARGEABLE-BATTERY-1800mAh-1-5V-ALKALI-MANGANESE-/170734271386?pt=UK_ConsumerElectronics_Batteries_SM&hash=item27c08e3b9a

found some information on wikipedia

seems they can be a bit fragile if not looked after

I wouldn't bother with them. There aren't any 1.5v rechargeables that are worth messing with that I can find. They cannot handle high drain devices, like flash guns, cameras, etc. They also need a special charger, most typical nimh chargers won't handle them. Anyone else know of any 1.5v rechargeables that can be used in high drain devices?
