Can anyone recommend a good battery tester and whether there is a similar tool I can buy to test the charger?

Also how can I tell what sort of leisure battery I have ? (gel? acid? Does it matter??


The extent of my knowledge in anything electrical is that I know there are volts and amps, but I haven't got a clue what they are or why they are different.





I think the best thing is for me to test something and see what isn't working. And then ask you good people more questions.

Thank you
