Alkaline battery capacity detection method and the other as a primary battery, with the rechargeable battery are different. Generally use constant resistance discharge, that is, the battery and a specified value resistor in series with discharge, and then measuring the discharge voltage falls below a certain voltage value (typically 0.9V) when the discharge time to be measured. Therefore, the alkaline battery discharge capacity has long been used to represent the time.
In the detection of alkaline battery discharge time are generally two kinds of 3.9Ω and 10Ω discharge method, two methods are 0.9V for the termination voltage. Below Xin Yong-Jin battery on the 5th and the 7th alkaline batteries, for example, need to be noted that, Xin Jin Yong battery alkaline battery capacity test method is through the same device parameters to achieve the following debug data, and thus the discharge current is balanced.
1, LR03 alkaline batteries (7): 3.9Ω discharge mode discharges approximately 2.6 hours; 20Ω discharge mode discharge time was 18.5 hours. If you switch to 500mA current discharge time is about 55 minutes.
2, LR6 alkaline batteries (the 5th): 3.9Ω discharge mode discharges 6.7 hours, 10Ω discharge mode discharges 19.7 hours; if the switch to 1000mA current discharge time is about 54 minutes.

If I have to be measured in × × mAh alkaline battery capacity, then here would involve the discharge current, discharge current alkaline battery capacity with a great relationship, a small current capacity than the release of the next release of a large current capacity to much larger, because of the large current alkaline battery capacity will be plummeted. Typically, ordinary alkaline batteries aa small-current discharge capacity of between about 1800-2200mAh. Ordinary alkaline batteries aaa small current discharge capacity of between about 900 ~ 1200mAh.

As can be seen from the above analysis, testing alkaline battery capacity is constant resistance discharge, in fact, alkaline battery capacity and discharge current have a great relationship. Thus, for an alkaline batteries, in order to measure the discharge time of the alkaline battery capacity must explain discharge system.
