Query: wrong battery, i don't know if it will matter

should be 600mAh, got 700mAh from seller. I could have just bought this battery at the store, and gotten my project done faster and cheaper at the same time. Unfortunately, people at Radio Shak don't know anything so they couldn't tell me the difference and I was worried. if this battery ruins my shaver, expect me to update this post; if this is it, it doesn't matter if you use the 700mAh.
