Product Description:
R20 Size D UM1 Battery
1.Why choose our R20 batteries?
Quality
With over 18 years' experience in battery
business, we guarantee each single piece of battery is reliable in quality.
Service
Efficient and excellent service is the basic requirement you can expect from us.
Responsibility
Your satisfaction with our R20 batteries and our service is our responsibility.
2.Performance:
1)Our R20 batteriy is made of high quality raw materials which have been inspected strictly before usage.
2)Our workers and technicians closely watched each step in the battery production processes, strictly executed the quality management system to insure each battery up to IEC standard.
3)Our R20 battery has the characteristics of high capacity, long-durability, super leak-proof, good performance of continuous discharge, long time of intermittent discharge, and it has low decline rate of capacity.
3.Chemical reaction:
In a zinc–manganese dioxide dry battery, the zinc can is the negative terminal through which the electric current flows into the device. The zinc is oxidised according to the following half-equation.
Zn(s) → Zn2+(aq) + 2 e− [E° = -0.7626 volts]
The positive terminal is a mixture of chemicals – usually a mixture of manganese dioxide powder, carbon and an electrolyte to increase the electrical conductivity. A carbon electrode rod also is placed inside the middle of the battery, connecting the two metal-capped ends of opposite charge and serving as the positive terminal.The reaction is as follows:
2MnO2(s) + 2 e− + 2NH4Cl(aq) → Mn2O3(s) + 2NH3(aq) + H2O(aq) + 2 Cl− [e° ≈ +.5 v]
and the Cl− combines with the Zn2+.
There are other possible side-reactions, but the overall reaction in a zinc–manganese dioxide battery can be represented as:
Zn(s) + 2MnO2(s) + 2NH4Cl(aq) → Mn2O3(s) + Zn(NH3)2Cl2 (aq) + H2O(l)
We promise to provide you with high quality R20 battery as well as high efficiency services.
