Advantages and disadvantages of nickel hydrogen battery.marine battery for trolling motor wholesale

　　Advantages: low price, strong versatility, large current, environmental stability.

　　Disadvantages: large weight, short battery life.

　　The design of NiMH battery originates from NiCd battery, but there is great progress in improving the memory effect of NiCd battery. The main change is to replace the cadmium used in the negative electrode with hydrogen storage alloy, so the nickel metal hydride battery can be said to be a typical representative of material innovation. The pollution caused by nickel metal hydride battery is much smaller than that of nickel cadmium battery containing cadmium. Therefore, nickel metal hydride battery has gradually been replaced by nickel metal hydride battery.

　　Except for a few lithium batteries that can be used once (NIKONEN-EL1 and 2CR5), most of the lithium batteries do not have battery alternatives, which is troublesome for going abroad for a long time or for a large number of users. NiMH batteries do not have such a problem. Digital cameras using NiMH batteries can usually use alkaline batteries instead.

　　In recent years, more and more digital cameras use nickel metal hydride batteries, and battery manufacturers are optimistic about this market. They have introduced high-capacity nickel metal hydride rechargeable batteries, making the technology of nickel metal hydride batteries advance by leaps and bounds, the capacity is also growing, the service time is comparable to that of lithium batteries, and even the chargers are becoming more sophisticated, and the charging time is greatly shortened.
