Re: [PSUBS-MAILIST] Ultracaps for submarines?

[Marc de Piolenc <piolenc@archivale.com>]

Thanks for the link.

What I now think I understand is the following:

Ultracaps' main advantage is that they are rapidly rechargeable. They 
can also tolerate a very high discharge current.

Their main disadvantage, other than cost, is that they behave like any 
other capacitor - that is, their voltage drops as they discharge, unlike 
storage batteries which have a fairly flat voltage curve until just 
before full discharge.

Best,
Marc
