    The Power Of Volts and Milliamps!!

    It has been quite a while since I rebuilt my Rollei 6000 series batteries. One was rebuilt around 2000 and the other around 2005 or so. As you may know the Sanyo Cadnica KR-600AE 2/3A batteries are no longer made, but there are replacements in that size with much higher milliamp rating. I went with these: http://www.batteryspace.com/nimh-rec...compliant.aspxClick image for larger version.

    Here is a battery that I last rebuilt quite a few years ago. It read 6V when I took the picture. I tried to restore it with some charge/discharge cycles on an automated charger without success. The pack with the yellow batteries measured 0V.

    I put the new batteries in a box and used super glue to hold them together:

    I just got back from shooting using the new battery. It really restored the camera to perfect function. The last few years, every time I picked up the camera the battery was dead. Charging only lasted for a day and even then the peak voltage was low.

    I'm working on an adapter plug so I can use an automated/computerized charger. The pins need to be exactly 1.5mm. I'm searching for suitable materials.

    Hey, you know you can buy the cells with solder-tabs pre-installed (designed for making up packs!) instead of contact nubbins? That way you don't run the risk of thermal damage to the battery's chemistry when you solder the pack together.
