I bought this refurbished Macbook Pro 2010 from ebay. Everything works fine, but it seems that when i click on the charging icon it sometimes says "service battery" when its on low battery. If i happen to charge it, the message goes back to normal. When i am charged fully i do not see this message until it goes below a certain level around 50%. I have about 400 cycles in this laptop, so should this be something that i dont have to worry about?
edit: I looked at my battery health, it is at 77%
