Best place to buy replacement laptop batteries?

[RTSDaddy2]

Not sure if I put this in the right posting area, but I have a Toshiba Satellite M45 that I need to look in to getting a new rechargeable battery for, and I'd like to do so as inexpensively as I can. 

Any suggestions?  Thanks ahead of time!

I don't know if it's the cheapest, but I just bought a replacement battery for my Satellite M105 at Batteries Plus:  http://www.batteriesplus.com/  It cost about $100.

They have a retail location right down the street from me.

Being how Georgia's always last on some of these stores list of places to put one, and having never heard of it, I figured there wouldn't be any close around me.  Much like you, there's one within 2 miles of my home...and it'll definitely be worth the look-see if I can save $50 - 60 dollars.  Thanks!

Actually, there are quite a number of these stores within 15 minutes of my location, apparently.  Good grief, do I not pay any attention to my surroundings when I'm out and about? Or is it just because 40 looms on Saturday!

Batteries Plus rebuilt the battery pack for my handheld police scanner radio. Cost me about $30 versus buying a new battery pack for $50 from the manufacturer. All around a good experience with Batteries Plus.

Try these guys on ebay, I bought two battery's from them one for a p133mhz laptop. The other was for a laptop only sold in Korea.  I got just over 4 hrs use from both battery's.
