Hi there Guys and Gals
I am starting to design a new Project which I then hope to bring to market.
The theory is all laid out the various components are all locate.
The electronic components are just about there.
The current drain I’m expecting to be very low, I don’t yet but at most it will be less than 5 amp’s.
As you can fully imagine I do not want to give to much away at the moment, but what I am looking for is something round the 6v to 9v range.
But what I really need is the staying power.
I never came across this problem during my career.
If you need further information please ask.
Tony

Battery selection is about how you decide compromises.
For example, here’s a 6 volt battery with a decent capacity of 210 amp-hours:

The 64 pound weight and lunchbox dimensions are ok, right?
No? Ok, here’s a table of really small & light lithium manganese batteries.
Most are 3 volts but you could use two in series.

That they’re not rechargeable and have relatively low discharge rates is ok, right?
No? Ok, here’s another one from the same vendor, quite configurable output voltage, relatively compact:

However, it falls short of your (relatively high) 5 amp peak discharge and it’s sort of expensive.
As you can see, it depends on where you have flexibility in your specifications.
