Ok, thanks for that. What an eye opener, I had no idea.

And the batts, join them all together irrespective of their values?

No, unless they are new and of the same capacity - but if you are using cheap used ones that owe you nothing, you can do what you like with them.

Thanks for all your help guys, appreciate it.

I think I'll look in to capacitors. Although their capacity is small compared with a battery, so is there size & weight, and they can drain them right down, as long as you keep the last volt or two.
 
Now all I need is a supermarket that's getting new tube lights and skipping the old ones Smiley

Capacitors dont store any energy why would you want them?Huh?

That is exactly what capacitors do!  He has likely read about the super capacitors, graphene and all that.

Good luck to him.  They have been touted as the "coming" storage solution for several years but so far have not yet proven to be a commercial success.

The OP is looking at collecting capacitors out of supermarket fluorescent lights. They do not store any energy, maybe 1000th of an amp but nothing usable. Even a car multifarad capacitor will discharge almost immeadiately when connected to a lightbulb.  We are not talking about new super expensive capacitors here.

I also have a Ultracapacitor 350F SixPack Module


I got the impression he wants to use the salvaged florescent fittings for providing addition illumination - he allready has some form of high performance capacitor.

Just as an experiment I thought I'd give the 350f supper capacitor pack a try on it's own and see what would happen.
It worked ok in the day, draining down to around 10 volts, but at night it ran out after only 5 minutes.  I knew it wasn't going to be good.
I fitted an led volt meter to the battery terminals to keep tabs on the voltage, after 2 or 3 days of rainy cloudy weather I popped back in to the garage, unfortunately the volt meter drained all the juice from the capacitor pack.
The voltage regulator had it's hissy fit and refused to work, even after fully charging the capacitor pack (with a car battery).
So the old golf cart battery back on, and the charger still didn't want to know, I had to threaten it with a screwdriver before it sprang in to life.

Anyhow, the answer to my question is, yes capacitor packs are good if you have enough of them. A 350f pack (120) is nowhere, a 3500f (1000+) would behave more like my 20ah golf cart battery (5 from a car boot sale).


Oh, while I'm here. Have you seen people on youtube claiming this little supper capacitor pack can start their cars and trucks?
Well the pack that I bought which was exactly the same, started my 1.2 Renault Clio only once, badly, then died.
