1.5V AA 700mAhAA 1.5V rechargeable alkaline battery (1 pcs)

Alkaline rechargeable battery is an upgrade to the traditional alkaline dry battery raw material formula and manufacturing process. It has the characteristics of repeated charging. It has the same compatibility as ordinary 1.5V alkaline battery, high voltage, no memory, low cost. It is its advantage. In use, it is necessary to strictly pay attention not to overcharge and overdischarge. If you use it, you can improve the battery life.

This product is used in toy cars, electric toys, sphygmomanometers and other products that consume a large amount of electricity and can be used with the charge (working current is greater than 300mA). The cycle life can be extended.

PS: Please choose a dedicated rechargeable battery for your digital camera. Don't choose this product.

Since the alkaline rechargeable battery has the characteristics of "inertial memory", it is recommended that the charging be continued on the original device after use.

It is not recommended to use it for a long time in products with low power consumption (less than 200mA) such as remote control, clocks, etc. (it is easy to cause the zinc material inside the battery to be exhausted). If it is needed, it is recommended to periodically charge to intensify the activity of the material.

Q: Is charging safe?

Answer: Alkaline rechargeable battery is zinc-manganese material. They are non-toxic and can be safely recycled. In the packaging technology, the positive electrode and the outer casing are designed in one piece, and the special pressure relief hole design on the bottom is for safety reasons. When the battery is overcharged, it will be discharged through the pressure relief valve. Come out, part of the electrolyte flows out (not exploding, it will not splash, you need to wipe off the liquid in time, do not enter the eye, the liquid leakage battery is discarded)

Q: How is charging efficient and safe?

Answer: When using alkaline rechargeable batteries, pay attention to shallow use of charge, use with charge, not only maintain the advantage of high voltage, but also reduce the risk of over-discharge! Pay attention to the temperature of the charge, avoid the battery over-saturation and leak! It is recommended to choose our special alkaline + NiMH dual-use self-stop charging, safe and secure!

Q: Can alkaline zinc-manganese batteries be charged?

Answer: Alkaline rechargeable battery is an upgrade to the traditional alkaline dry battery raw material formula and production process, and it is widely used in foreign countries. It maintains the characteristics of high-voltage alkaline batteries (about 1500 ~ 2300 mA on the 5th) and high voltage (1.5 ~ 1.6V). It has the characteristics of repeated charging, high voltage, large capacity and low cost. The advantage, of course, the short charging life is also a disadvantage, generally 30 to 50 cycles, not over-discharge, shallow discharge can greatly improve the cycle life of the battery.

Q: Is the real capacity?

Answer: The special process of alkaline zinc-manganese rechargeable battery makes its initial voltage and power very high, which is similar to the capacity of a genuine alkaline dry battery (1500~2100 mAh) . However, the rechargeable battery cannot release all the power, and it needs to retain 1/3 of the capacity, otherwise it will be damaged by overdischarge (zinc material is exhausted).

Alkaline manganese rechargeable battery technology

      Rechargeable alkaline zinc-manganese battery An improved alkaline zinc-manganese battery, referred to as RAM, that can be reused by charging. The structure and manufacturing process of the battery are basically the same as those of the alkaline zinc-manganese battery.

    In order to achieve recharging, the battery is improved on the basis of alkaline zinc-manganese battery: 1 improve the positive electrode structure, improve the strength of the positive electrode ring or add additives such as adhesive to prevent the positive electrode from swelling during charging and discharging; Doping, improve the reversibility of manganese dioxide; 3 control the amount of zinc in the negative active material, control manganese dioxide can only be discharged by 1 electron; 4 improve the isolation layer to prevent short circuit of zinc dendrite penetrating the isolation layer when the battery is charged .

  The charge-discharge cycle performance of the rechargeable alkaline zinc-manganese battery is inferior to that of the conventional secondary battery, and the charge and discharge system has a great influence on the cycle life of the battery. At present, the service life of the full charge and discharge cycle is only about 50 times.Do not overdischarge when using this type of battery, shallow discharge can greatly improve the cycle life of the battery. The discharge reaction of the battery is the same as that of the alkaline zinc-manganese primary battery, and the reverse reaction of the discharge reaction occurs during charging:

  MnOOH+Zn(OH)2→Zn+MnO2+H2O

There are only a few large-scale production companies in the United States and Canada, and China also produces such batteries, with more OEMs.
