Practical mainly carbon dry cell batteries and alkaline batteries, carbon batteries and alkaline batteries leak leakage both identical nor different places.
Battery leakage commonly associated with dry seal craft, which is manufactured from dry batteries for the links. Excessive use can cause battery leakage discharge, usually because the output current is too large, continuous discharge time is too long, causing the battery temperature. Low current discharge leakage will use a long time, because the battery termination voltage is 0.9V, in theory, to work as long as the voltage is below this are likely to cause battery leakage, the voltage may leak in the design of some manufacturers promise 0.6V, the best promise 0.3V, but the latter is difficult to achieve.
Use of irregularities or the battery design flaw will cause the battery positive and negative short-circuit, making the battery internally generated large current, led directly to the battery hot body, followed by a surge in temperature and pressure of the gas may be break through the valve, causing batteries to leak.
The battery leakage are two common, there are some differences between the two. First, the leak is not the same principle, zinc carbon battery casing to participate as a negative skin reaction when the battery is running out will be thin, especially 0.9V still continue to use the following words will produce battery leakage danger, and alkaline battery leakage is not caused by a chemical reaction, in addition to sealant aging reasons, there is a possibility of improper charging the battery, so that the internal pressure rises caused by battery leakage. Secondly, the battery is not the same liquid leakage, carbon battery is zinc chloride and ammonium chloride liquid, and a liquid alkaline batteries is potassium hydroxide.
Battery leakage can severely corrode electrical appliances, so users want to prevent battery leakage and leakage occurred in the battery to take decisive measures. For example: Do not mix battery, long-term without the battery should be clean, safe storage. Of course, in the event of battery leakage, should be resolutely discarded because of leaking batteries without use value.
