I ordered these batteries on October 6th, they were shipped on 9th, and I received them on November 25, about 30 working days, so a little more than the 10-20 business days estimated by MITB. It was a long wait, but they arrived, well packaged, and in perfect condition.

They are exactly like what is in the picture on the MITB web page; I charged them up, and they both worked perfectly. Thanks, MITB!

The battery has a very good quality. It is LOT better than the 2400mA battery that I was using before. One thing is to be remembered that if you place an order that includes batteries then MITB cannot send that order through Expedited Courier Service. The whole order will have to be sent by the time consuming ordinary registered mail no matter how much money you may be spending on your total purchase. Experience tells that the best solution is to order the batteries separately if you want other items in your order to be delivered fast.
