My rule of thumb on supplies is +/- 5%. In the case of your battery you won't be stressing the battery since it's rated to be charged to ... only 0.2 Volts higher.

What can I write? How about "it will be fine."

Tip: FOLLOW THAT FIRST TIME CHARGE INSTRUCTIONS TO THE LETTER. If it asks you to charge it 8 hours or overnight please do so to get the best life out of your new battery.
