A really professional battery analyzer is made by www.westmountainradio.com in Waukesha, WI Phone (262) 522-6503. I have one since 2013 to keep track of condition of about 75 AA NIMH batts and about 40 D cells. It works with your computer via a USB connection. Has features such as programmable discharge rates, stop discharge at a a programmable voltage setpoint and is compatible with all the different chemistries. Sores history information on your computer and you can print a voltage versus time during the discharge period.

Widely used by Drone, Amateur Radio Folks and other applications. The one I have is a model CBA IV Computerized Battery Analyzer. About $ 200 dollars.

And yes Eneloops have a much lower self discharge than conventional NIMH cells.

I have available a complete set of four Nikon Auto-Tele Nikkors. Specifically: Two 400mm F4.5, One 600mm F/5.6, One 800mm F/8 and One 1200mm F/11 Lenses and three of the AU-1 Helical focus/auto diaphragm units. These are two part telephoto lenses made by Nikon for the mid 1960's Japanese Olympics. There is the "front part" the glass optic and the "back part" the helical focus and auto diaphragm unit. They screw together. These lenses are compatible with any F mount Nikon film or digital camera. Also have two Nikon L39 (skylite) 122mm in leather cases. Condition is very good and wish to sell all eight major pieces together. Also have original instruction book (not a copy).

Please contact me for more info.

I see you are a Nikon "collector" You might be interested in some long glass I have available. Specifically I have the complete set of four Auto Tele Nikkors: 400mm F/4.5, 600mm F/5.6, 800mm F/8 and 1200mm F/11. These were made for the Japan Olympics mid 1960's. All are unique two part telephotos with the optics (glass, the front part) interchangeable with a separate helical focus and auto diaphragm unit (the rear part). I have three of the AU-1 focus/diaphragm units plus a spare 400mm optic. Would like to sell all eight pieces together. The condition is very good. Also have two Nikon screw in 122mm L39 (skylight filters) and original instruction manual. If you are not interested perhaps you know of someone that is?
