Before any readers get mislead by the Sterling Power article
in Brian’s link can I suggest they quickly drop to the bottom of it and read
Here you will see the whole emphasis is on what is “best”
for “fast charging”.
This is because the quoted article is completely out of
context, with our battery requirements; it is targeted at leisure marine use,
not caravan habitation power support.
In a caravan you don’t require the battery to cold start a
large propulsion battery and then grab the opportunity to recharge it as
quickly as possible from the brief running period of the engine.
Our requirement is so totally different, making nonsense of
using the article to support caravan habitation battery selection. Certainly
not the best article I have seen for our application, if of any use in that
context at all.
In answer to Brian’s question to me:
No I don’t believe batteries made to nationally recognised
Japanese or USA standards are rubbish, nor have I in anyway said or implied so.
If you would like to furnish us the details of exactly which
of these national standards and the batteries you are referring to, are
compliant with, then we can constructively look into their suitability for our use.
