It will be fine. Out of my three K-7 batteries, the original Pentax one is still going strong after some 2.5 years. The second one, off eBay, lasted about a year and a half, now not holding charge too well. The third one, again off eBay, is also beginning to show signs of old age after a year or so. In use I usually alternate between two batteries, running them well down and recharging as soon as possible. In practice, there seems to be little discernable difference between the 1860 mAh and the 2500 mAh ones.
