We've purchased quite a number of batteries for testing. These represent the most common batteries around here and fall into two major categories - alkalines, and low-self-discharge (LSD) rechargeables. We also have the Energizer Lithium which is the only one of its' kind here but since they are qui...

I decided to bite the bullet and swapped out all the load resistors (1ohm) for a set of better matched ones. This entailed measuring the resistors at the shop and picking those that matched up. Unfortunately our digital DMM is only good for 10miliohm resolution. Putting these in we are looking at ab...

We repeated the test using CH2 and CH4 which are the most closely matched channels and we did get a more closely matched graph as follows:- ReCyko-5.jpg The reported capacities were also very much closer, expectedly:- ReCyko1 2110mAh 2468mWh ReCyko2 2124mAh 2470mWh This gives us good reason to use b...

Okay, we re-tested the ReCyko's in different holders to see if the general trend holds. Results were:- ReCyko-4.jpg Reported capacities were:- ReCyko1 2103mAh 2443mWh ReCyko2 2121mAh 2441mWh Seeing as to how the CH1 (blue line) is still higher, we may have a calibration type of issue. I think it mig...

We charged the ReCyko's again, taking the following charge:- ReCyko1 2005mAh ReCyko2 2110mAh The actual charge will be higher since we allow for 2-hours (and more) of topping up. The test curve is as follows:- ReCyko-3.jpg Reported capacities were:- ReCyko1 2136mAh 2435mWh ReCyko2 2107mAh 2432mWh Th...

After 2-days of break-in, the ReCyko's were showing the following capacities:- ReCyko1 1996mAh ReCyko2 2041mAh Putting this through the tester we got:- ReCyko-2.jpg Reported capacities were:- ReCyko1 2115mAh 2449mWh ReCyko2 2059mAh 2415mWh Bearing in mind that we are discharging to 0.8V rather than ...

These are some of the batteries that are lined up for the test. So far, I'm not including regular Ni-MH rechargeables, on the LSD types. A couple more that I want to include are the Panasonic Oxyrides, SONY LSD's if there are any, perhaps Kodak, several other cheap house brands, Duracell Ultras, and...

As a last check of the system consistency, I charged the GP1600's in the ReCyko+ charger and put it through the tester again, this time with the batteries in reversed order (in all in different slots). The results are as follows:- GP-1600-1234ABCD-12.jpg The reported capacities are:- BATT1 1199mAh 1...

I finally decided to profile a set of new ReCyko's after running them down a bit in my audio recorder. The batteries only took about 800mAh so it probably wasn't really empty. In any case, I ran it on the tester CH1 and CH2 and this is what we got:- ReCyko-1.jpg The reported capacities were:- ReCyko...
