Stumbled onto Green Rhino Energy's site earlier today, and saw some interesting claims in the FAQ.
------
-Can a Crystal Battery™ be discharged a 100% Depth of Discharge?
Yes, Crystal Batteries™ can be discharged in full frequently, even to 0 Volt. This makes Crystal Batteries™ extremely resilient for deep discharging. Deep discharging will reduce the cycle life.
-Do Crystal Batteries™ charge faster than lead acid, lead gel or AGM batteries?
Yes, Crystal Batteries™ can be charged up to 3C (In Boost for short periods) without any impact on their cycle life. This means they can be charged 2-3 faster than other batteries. Standard charging requires 0.3C for GRGS, GRLS, GRFT range and 0.2C for GREV Range.
-Do Crystal Batteries™ sulphate?
Due to the construction and chemical reaction inside a Crystal Batteries™, sulfation hardly ever occurs. Crystal Batteries™ contain less sulphuric acid. They do not contain toxins such as cadmium or antimony either.
-What is the lifespan of Crystal batteries™?
Crystal Batteries™ have a design life of 18 years. For Cycle life check our data sheets and catalog for specific information.
-------
To me, these seem very competitive to lithium cells (except for the weight). No 50% discharge limits, no sulfation, 0 volt recovery, up to 3c fast charging, and an 18 year calendar life.
I'm a LiFePO4 guy, but depending on cost, I might consider these for a stationary system.
Does anyone have any experience or opinions on cells like this? I'm sure some of the claims are exaggerated for advertising, and I did catch where it said that "deep discharging will reduce cycle life", but if they really perform like they say, and retain the lower cost of Pb vs Li batteries, I imagine that they will be the "next generation" of lead batteries.
