I went to buy a battery charger this morning & was startled at the price. It occurred to me that I actually had a rather nice one at home already - a
200watt PSU recently salvaged from a 'pooter on it's way to the skip.We'll see if it charges batteries!

13 quid, Lidl's rather excellent full-auto ones (saw some just this week).
You will need to load the 5V output for it to supply anything on the
12V output. You will also need to trim it as you won't get much charge going into a battery at 12V. The highest voltage I have ever gotten out of one was around 13.5V. I humbly suggest it will be a waste of time.
I've found those 12V (nominal) ''wall wart'' transformers to be great for charging lead-acids. They take ages with an output around 800mA but can be left alone with no danger of ''boiling'' the electrolyte away!
