How come the last 2 of my laptop battery chargers stopped working?

I have a Dell Inspiron 1520 laptop and my last charger I had stopped charging, but other peoples chargers still work on my computer. I bought a new replacement charger, and after about a month, this charger died too. I have multiple batteries so I don’t think it’s the battery. What should I do to prevent this from continuing?

How do I make my laptop battery last longer off power?

To put it in simple terms, I keep my laptop constantly charging with the power cable and hardly ever just use the battery because it doesn’t last very long without the charger in.

I’m getting a new notebook delivered tomorrow and I’m wondering what the best methods are for fantastic battery life? For example, I’d like to take it to college with me and maybe to coffee shops for a few hours. How do I make it last without having to keep it on constant charge?

How long will the lithium ion battery in the SanDisk c250 1gb MP3 player last?

I’m asking about the overall lifetime of the battery, not each individual recharge. I have read that lithium ion batteries in laptops can lose up to 20% of their max charge per year in a 77F enviroment.
Sorry, i ment to type C240, NOT 250.
