    I think my PRAM battery (Or is it a capacitor in the new models?) is dead or no longer holding a charge. My battery still holds a 92% of orignal capacity charge with 498 cycles on it. The computer in question is a 2010 Macbook pro.

    The reason I suspect that its dead is that every time my battery goes completely dead and I'm without an outlet for even a few minutes, then go to plug it back in instead of just resuming it starts back up from scratch and the date and time info are reset. So Is this PRAM or something else? I'm not against doing a DIY fix by replacing the battery myself but I'm unable to find the parts for my model. What do you think I should do?

    Theres no PRAM battery, its shared with the main battery. Most likely your battery is going bad so when you drain it completely, it literally doesn't even have the charge to keep PRAM going.
