You already sent your camera off to Nikon, yes? If not, or, for future reference, go to Menu, Setup Menu, press the > on the direction pad, go to Battery Info and press the > key to select it. Your Battery Info Screen opens.
Bat. (Battery) Meter: % of power left in your battery
Pic. (Picture) Meter: how many images you've taken so far using this charge
Charging Life: (0-4): Is your battery status. A small yellow triangle indicator is above a number from 0-4. 0 displays your battery is new and 4 displays you need to consider replacing your battery.
Actually, everywhere I've checked advises 40 per cent as the best charge level for long term storage of a li-on battery. I wouldn't consider shooting only several times a month as qualifying for long term storage or anything worth worrying about.
The good news is that for the amount paid to Nikon for repairs (does not apply to sensor cleaning alone), not only are they fixing any related issue, but they also go through the body, replace any OTHER issues or pending issues that they see and return it to factory spec.
