Why is rechargeable battery 1.2 volt

What is the difference between alkaline and manganese batteries? In Japan, Europe and the United States, high-powered alkaline batteries are the norm, but from a global perspective, cheap manganese and Dry batteries are the most commonly used. Let's take a look at the differences.

For devices requiring a small current load, such as remote controllers. Dry batteries consist of three materials: metal, metal oxide, and electrolyte.

Manganese dioxide is used for the positive electrode, zinc chloride for the electrolyte, and zinc for the negative electrode. Suitable for devices that use high continuous current. Alkaline batteries produce higher current than manganese. This is because the electrolyte consists of potassium hydroxide, an alkaline-aqueous solution that enables a high flow of current. What should I look out for when recharging batteries for the first time?

When you use a battery for the first time, or a battery that has been unused for a long period, it may not be necessarily charged fully. In this case, fully discharge and charge the battery times. Dry batteries have a slightly higher voltage than the actual working voltage required by the appliance. Though the nickel-metal hydride battery is 1. Basically, almost all appliances that require a dry battery can also use Ni-MH battery. Please be aware, though, of exceptional cases where only dry batteries can be used.

Is it a fault if my batteries get hot while charging? This is not a fault. It depends on the capacity of the rechargeable batteries and the charging conditions of the chargers, but both batteries and charger will generate heat. Even if the batteries become even hotter for whatever reason, there will be a protector circuit within the charger to prevent any damage to the batteries or any safety issues. However, you must never cover the charger with anything that would block off ventilation during charging, such as a cloth or plastic sheet.

In conclusion, the 1. However, every battery chemistry has different characteristics including voltage across a discharge cycle and open-circuit voltage.

Each type of battery chemistry yields quite different characteristics, including terminal voltage. They put a tiny switch-mode voltage regulator in the cap! Of course the conspiracy theorists said the non-rechargeable battery companies were paying the gadget makers to do this deliberately, but the reality is that it's simply been the growing prevalence of low-dropout linear, and switch-mode, power supplies that allows gadgets to work down to much lower cell voltages.

Add a comment. Then, it drops constantly to well below 1. Finally, it drops to around 0. Most equipment will work happily on anything between 0. Unlike alkaline batteries where the voltage drops quickly, rechargeable batteries offer a more constant voltage around 1. That is why the latest rechargeable batteries will actually outperform alkaline batteries in equipment calling for a constant and high level of energy input, such as digital cameras, flashes, camcorders, computer keyboards and mice, portable phones, DVD players, toys, gadgets - well just about anything.

You should never attempt to recharge a normal alkaline throwaway battery in any of our NiMH battery chargers as this could result in leakage from the battery and damage to the charger. There are some battery charges that claim to be able to recharge throwaway batteries but alkaline single use batteries have not been designed to be recharged and in our experience such chargers should be taken with a pinch of salt.

Our advice would always be that if you want to recharge batteries invest in proper rechargeable batteries which have been designed to be recharged hundreds of times with consistently reliable performance. When charging rechargeable batteries, they can noticebly increase in temperature due to internal resistance and the charging process in general and batteries therefore may feel warm during charging and when the charge is completed.
