Types of batteries

Battery charging cycles

A charge cycle occurs when you use 100% of your battery's capacity. Lifespan is defined by total cycles before capacity drops below 80%.

Parameter	Technical Description
DoD	Depth of Discharge level.
SoH	State of Health of the cell.

Lifespan Calculation

Maintain the battery between 20% and 80% to maximize chemical stability and longevity.

Advantages

Controlled charging reduces heat and prevents lithium plating.

Note: Use original chargers for optimal safety.

Button batteries

This type of batteries are very common in devices such as watches, computers, calculators, remote controls etc .. thanks to its small size is ideal for small devices.

Its very peculiar shape is of cylindrical and flat type, with two discs, one upper connected to the positive pole (4) and one in the lower part connected to the negative pole (5).

According to the model we will find them with voltages of vary between 1.2and 3 V (3).

This type of stack can be divided into two large groups:

Primary batteries: They are depleted as they are used.
Secondary batteries: They can be recharged by passing an electric current through them in the opposite direction.

Since there are numerous types of button-type batteries in the market, it is advisable that before buying it, the model of the battery is verified, all battery models inu upper part indicate the model, normally this reference begins with two or three letters (1) followed by a numbering (2).

It is mandatory to dispose of exhausted batteries at a recycling point, as these types of batteries are highly polluting due to their composition.

Metal cathode (+).
Zinc anode (-).
Zinc (Electrolytic).
Isolation.
Separator (porous).
PaAg2o sta.

Inside the button cells you will find 4 types according to their chemical composition.

Alkaline: They are the most common, are composed of zinc as anode and manganese dioxide (MnO2) as cathode, its voltage is 1.5 volts, the most common: LR54, LR44, LR43, LR9.
Lithium: Its chemical composition can be Manganese-Lithium Dioxide, LiMnO2, Polycarbonate-Lithium Monofluoride or Thionyl Chloride-LiUncle Tadiran. The most common, CR1025, CR1216, CR1220, BR1225, CR1612, CR1616, CR1620, CR1632, CR2016, CR2025, BR/CR2032, BR2325, BR/CR2330, CR2354, CR2450, CR2477, CR3032. Their voltages vary between 3 and 3.6 volts.
Silver oxide: Very good at low temperatures, its voltage is 1.55 volts. The most common, SR41, SR42, SR43, SR44, SR45, SR48, SR54, SR55, SR57, SR58, SR59, SR60, SR62, SR63, SR64, SR65, SR66, SR67, SR68, SR69.
Zinc air cells: Normally used in hearing aids, their voltage is 1.4 volts., The most common: PR70, PR48, PR41 or PR44.
