I saw those the other day and was amazed that they are trying to charge $19.99 for a apck of 4.
I haven't use those but I can tell you way back when I went in and paid something like $12 for two 1200mAh and then found that 1600mAh were the standard and could be bought for $2 per cell so radio shack was charging three times the price for less mAh. Also both those radio shack's started leaking a year or so ago so I tossed them and I still have Sanyo 1650mAH calls from 2001 which are testing out at 1000-1300mAh so it seems radio shack is charging too much for sub standard cells.
