Would using a 17"MBP power adapter on a older MacBook kill the battery?

    My kids used the wrong power adapter on an older MacBook and now the battery is dead. Battery less the 6 months old that I purchased from ifixit.com brand new. Don't know if it's related to it dying on me.

    No, the adapter won't kill the battery. It may be a defective battery, or it may have been improperly cared for. This should answer most, if not all, of your battery questions:

    does using a higher voltage charger not effect the battery? what does a larger laptop need extra power for? im wondering about this issue too

    It's not a higher voltage charger, just a higher wattage. Allows a larger battery pack not to overheat the charger. Using an 85 watt charger on a machine that only needs a 65 watt won't cook the battery. Using a 65watt charger on a machine that needs an 85 will make the charger hotter than a firecracker.
