[chevy57]

60W magsafe charger for my MacBook Pro 13 (mid-2010) s cord is worn. it s box ran too hot someday. I will look for replacement one. Can i use the 85w Macbook Pro charger on my 13" Macbook as a spare or will it damage it? it run cooler than 60W charger?

You sure can. the charger will not "force" the MB to take more wattage than it needs. The 85w are great replacements for the 60W

As stated in the CHARGING section of the following link:

Power adapters for Intel-based Apple portables are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple portable, you can use an adapter of a higher wattage without issue.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

I picked up an 85W adapter so I could leave the 60W plugged in in the living room, and the 85W in my office. What are the wattages on the new MagSafe2 adapters?
