[RE-wrenches] Battery chemistry

[frenergy]

Mark,

        It's probably just a brain fart, but it's lead-calcium

  Todd,

  Can you give us a comparison of lead vs lead cadmium?

  My understanding is that lead cadmium are suited for standby operations such as telecomm back up.  That means spending most of the time in float, with occasional short term high discharge rate with very high DOD available.

  How well do they cross over into a daily-cycle off-grid situation with moderate daily DOD?

  I know many on this list disagree, but this sounds SO typical for sealed batteries. It is why I never use em... never! If they are 5 years old, you are probably at the limit of their life. Replace em with flooded lead calciums and your customers (and you) will be happy for 20+ years.
