I need a new suggestions on a new extended battery for my OGD1

I cant remember who recommended the P.O.S. extended life battery for my OGD that i bought 2 months ago but its even worse now then my stock battery is, so I guess what i need to know is which is the best battery i can get for the d1 esp since im OC'ing pretty high I'm not have any OC'ing problems or FC's but the last battery i was told to get from here was decent for about 3-4 weeks and after that it turn to crap literally, my stock batterie will last 3 to sometimes 4 times longer then the extended batt. so can anyone help out of experience ? for instance im assumming the better the mAH rating is the better the batterie like i was told last time but i bought the highest i could and it was just crap. (prob BS brand, I really have no clue)
so few questions
1. Should i still go with the highest mAH rating available
2. id like to have a ext baTT that fits decent or even a case i can buy to cover it up a little bit
3. theres some pretty cheap high rating mAH batts available but im thinking to stay away from the cheap ones but i have no idea what the good brands are anyway and money isnt an option ill spend what ever i need to, to be able to max my cpu while im using it through out the day (probably 2-4 hrs of talk time and probably close to 2 hrs at most online messing around depending on how slow the work day is but i want it to keep as much charge as i can get it to throught the whole day.

can u guys give me some pointers or even link me to what i should be looking for ?
Thanks you guys so much in advanced.

p.s. Im not exactly a noob when it comes to the d1,d2 or even the tbolt and actually not even to this site i just usually dont post becase i always search for answers before i repost and look like a idiot. (now that i said that this is probably a repost )
but i would really appreciate any comments,opionions or links on this subject
Thanks again

 

Thanks bro im gonna give it a shot, I really want to upgrade my phone but really have no idea on a replacement to get that basicly has all the functionallity (after root ) that the og does.
I just dont want to go spend a ton of money (not eligable for upgrade for like 5-7 months if i remember correctly) on a phone and findout that its not rootable or even if it is with my luck I wouldnt be able to do half the stuff I can do with the OGD1.Dont get me wrong I would gladly spend $400-$700 on a new droid just has the after root capabilitys that the OG does I love the OG but Im Starting to have alot of problems with it

 

Ok This is probably a STUPID question but all the BP7X's I see advertised (ebay, cannot even locate on the verizon site) for the Droid 2, so is it still gonna work for the OGD1 ? Also am i gonna need to purchase a different battery cover to use with it ?
Thanks for all the help guys
