Eolic generator, battery highschool project electronics

[SebastianMarco]

Hi , we are a group of students from mexico from "Liceo Franco-Mexicano" trying to solve a problem that we have been looking forward to.
We are doing some research work about the batteries , (Pb type batteries)
Our teacher asked us to find out how to charge a battery and to monitor the level of charge.

It would be kind if you could bring us all types of information as possible about :
- The analogic signal

-To monitor as we said , the level of charge of the battery so we can be able to know when it is ready to work efficiently

Why haven't you tried Wikipedia and Google yet? There is every bit of information you could possibly ever need using fewer search terms that you made writing this post.
