Battery Health, should I worry?

[Mkl0461]

My late 2009 macbook fluctuates between 86% and 89%, 90% battery health.
Cycles: 121
I've had it for 9 months.

It used to be at 95% health than dropped over the course of 2 months.

I've calibrated but no improvement.

Is this normal? Because I dont wan't to be at 70% in another year.

The more you use your laptop, the worse the battery gets. Expect to buy a new battery approximately every 3 years if you want long battery life per charge.
