Problems solved by technology

Existing full-featured battery testers are bulky and take a long time to measure battery performance. Simple battery testers can only test the open circuit voltage of the battery, and cannot intuitively reflect the performance of alkaline batteries under high-current discharge conditions. load voltage

Abstract

The invention discloses a portable alkaline battery testing device which is composed of a timing circuit and a discharging circuit. The timing circuit is used for selecting motor rotation time, and the discharging circuit is used for measuring the size of negative pressure of a battery to be tested. According to the portable alkaline battery testing device, the size of the negative pressure of the battery to be tested is judged according to the rotation speed of a motor within a unit time. By means of the portable alkaline battery testing device, the size of the negative pressure of the battery to be tested can be obtained very conveniently, and due to the fact that judgment is conducted through the rotation speed of the motor, a testing result is very visual.

Description

technical field [0001] The invention relates to a battery testing device, in particular to a portable alkaline battery testing device. Background technique [0002] Alkaline batteries are widely used in daily life as a cost-effective primary energy source. With the increasing number of electrical appliances powered by alkaline batteries, such as digital products and electric toys, the requirements of electrical appliances for alkaline batteries are also increasing. high. At this time, the high-current discharge characteristics of alkaline batteries are particularly important. At present, the judgment of battery performance generally needs to rely on professional discharge test equipment. Existing full-function battery testers are bulky and take a long time to measure battery performance, while simple battery testers can only test battery open-circuit voltage and cannot intuitively reflect the performance of alkaline batteries under high-current discharge conditions. load...
