I have bought many of the 1400mAh cells.
I have a panasonic CD player, and they supplied 2 rechargeable cells
where there was an exposed part on the side of the cell which a 3rd
contact connected to to recharge. The cells supplied were 1000mAh
nicads.
I cut back the green plastic wrapper in the same way as the panasonic
cells exposing the negative terminal to connect to the 3rd terminal.
Charge fine. Works fine, Great battery life
Plus, the CD player can tell me when its low batt. with the nicads it
gave about 5 mins warning. with the nimh I get about 45 mins of warning.

Yes, they are nicad. If people were to try charging the rechargeable
alkaline "renewal" cells they may have a messy leakage of battery acid.
Plus sony cannot say for certain that it will charge other cells ok.
Covering there ass in case some mule puts dry cells in and try's to
charge them.

It will take longer, but most gear is built with decent charger designs
that will still fully charge it.

Yes, you will.
