My lifeline is dying.

Hello, I'm Mark. I damaged my lower back as a teenager and It's slowly getting worse. I'm 62 now and live alone and get by on benefit payments. I rarely leave home any more. If I do, I have to walk with a stick.

During the day, I spend most of my time in front of my laptop. I have a 2017 Macbook and my laptop's battery is dying. I constantly worry that when my laptop battery dies, the laptop will be dead too.

Please help me buy a new laptop battery.
