Battery problem maybe....

I've done a clean install of Windows 7 Ultimate on my old laptop. It ran good for a few days but yesterday, I noticed that a red X appeared on the battery icon saying that I should replace my battery. I didn't care about the message because this message had appeared a few times a long time before and it went away without replacing the battery. I was browsing a few youtube videos when it abruptly restarted and took me to the windows error recovery screen. I selected start windows normally. When it reached the desktop, it again restarted abruptly and took me there again. I selected Safe mode. In safe mode, it ran well but then I restarted and then it didn't restart till now, but still I googled about battery health problems and did an energy report scan from cmd. I attached the log so that it could give you some clues. Thanks.

Sorry for double post. Forgot to upload energy-report.log. Here it is.

It appears your battery is about dead.

Code:

Battery:Battery Information
Battery ID	3658QSANYO PABAS024

Yeah it could be because I've been using this laptop for years. I also saw in event viewer that it says -
"The computer restarted before shutting down cleanly". Anyway, if I notice anything else, I'll report.
