A battery source SANYO eneloop battery test samples: battery nets sent to me, the battery capacity is 1900mAh product wins samples: the nearest supermarket to buy, the production date is April 30, 2008, valid for one year, the capacity of 2300mAh
(2) the use of charge-discharge system Sunway BTS-5V/2.2A precision battery testing system testing, charging and discharging system are: to 600mA charge up to a certain capacity, then 1000mA slush Discharge cut-off voltage to 1V Because of the time, does not use conventional 0.2C (0.2 times the rated capacity) charge slush and discharge system, which uses a quick release of the fast charge mode, so do not reach the rated capacity and capacity, this is not the standard battery capacity is not known why.
3 experimental data a) the purchase of the remaining capacity of the battery will buy the battery, use 600mAh discharge to 1V
2) charge-discharge slush cycle test cycle that is called a discharge process, with the primary charging process of the battery pack is called a cycle samples due to charge and discharge cycles to verify, using the 600mA are thus charged to 2000mAh, and then discharged to 1V 1000mA The charge and discharge slush system, as a kind of product wins the rated capacity of the battery is 2300mAh, so his discharge efficiency than Sanyo battery samples, but does not indicate a kind of superior product wins Sanyo battery cell samples (due to time issues, only tested 200 cycles)
As can be seen from the above data due to product design wins samples battery Sanyo battery capacity than the samples to be high, so high efficiency, slush but due to the period 150-200 cycles, Xi'an large area cooling, decreased laboratory room, You can see a sample of the product wins battery capacity drops of more powerful, and Sanyo battery capacity retention samples or have been good
The picture shows the battery charging curve comparison chart samples, one can see the Sanyo battery charging curve of the platform above the sample product wins cell samples, cell samples described inner product wins the nickel hydroxide is oxidized more easily and better charging performance, high charging efficiency. Sanyo rechargeable battery platform slush product wins over the samples to be long, mainly slush due to the design capacity of inconsistencies caused by the amount slush of nickel hydroxide slush caused.
4) discharge midpoint voltage discharge midpoint voltage battery capacity is put half the battery voltage, typically this value as an important indicator of the size of the battery power, the battery will PISEN samples charge to 2300mAh, Sanyo battery charge to samples 2000mAh, take the first 50 cycle discharge index as a comparison
5) overcharge performance tests, the two batteries in accordance slush with the 10% overcharge and over-charging in the middle of a cycle of 400%, the recovery before discharge system, product wins Sanyo battery cell samples and samples are returned to the original level, the data shown below
4 Summary From a performance point, you can see samples of Sanyo battery performance battery basic product wins victory samples, but also useful to see the gap between the market price of:. Eneloop AA * 2 + battery charger kit, commercially available 150 yuan, while the Commercially available batteries of the same suit product wins $ 50. So both sides have merit it.
