5 out of 5 eggsVery Impressed with Quality and Price!

Pros: I rarely write reviews, but this battery really saved me. I had a biz trip earlier this week. The battery I had in my laptop was nearing it's death, which I realized when I arrived to my hotel (only held about 15min charge). I had a mobile presentation the next day at 3pm. So I went online from my hotel room and ordered this battery with the most expedited shipping available, realizing that even with the next day air it was still about $25 less than the competition with ground ship. I figured if it would get me through my meeting I would be all good and then worry about quality later. Well, I got the battery next day at 2pm at my hotel (thanks newegg!) but didn't have time to charge it. I hooked it up to my laptop right away with my fingers crossed, and it had 100% charge right out of the box!! This battery then went on to power my laptop without charging for about 4hrs! Very impressed with the quality and functionality, and also saved about 35% on price (not counting shipping)!

Cons: It took me a few clicks to see if this was the battery for my laptop. There should be some more compatibility info somewhere on product description in the newegg site.

Other Thoughts: I need a charger also sometime soon, does WorldCharge brand also sell chargers? I didn't see any on newegg, but would be excited to see if their chargers are anything like their batteries in quality and price.
