I have two Rollei 6000 series batteries for sale. One has been rebuilt using 1400mAh NiMH batteries (packs a punch!) and the other rebuilt with 600mAh NiCads. Both of them haven't been used much, only going through a few charge cycles. The NiMH battery will need to be charged in a charger like a Maha 777. I don't believe it is compatible with the Rollei charger. If you have a Rollei, you probably already know about the Maha charger. I used these in a 6003 so you may need to change the fuse depending on what camera you have. I would like to sell these together because I am lazy like that, so $100 for the NiMH battery and $90 for the NiCad one (plus shipping)
OR you can buy them both for $175 and that
includes the shipping (in the US). Paypal preferred.
