Batteries ER26500 3.6 v

Lithium batteries have the best ratio of capacity and performance, so the use of such batteries is the most preferred.

The ER26500 battery belongs to this category of products. This lithium power supply has unique characteristics, which will be discussed in detail in this article.

Specifications

In order to set the exact parameters of the ER26500 battery, it is not necessary to use a multimeter, vernier caliper or balance. A battery of this type is significant, so most of the information is applied directly to the case.

This information can also be duplicated and supplemented on the packaging, which, as a rule, contains 2 products. The main technical characteristics of the ER 26500 include:

This type of element is made using lithium chloride. This connection envelops the working electrodes with a thin film that prevents self-discharge. Due to this quality, the element can be stored practically without loss of electric current for up to 10 years.

The disadvantage of this technology is the need to “defrost” the battery, that is, a new battery must be discharged for 15 minutes with a current of at least 20 mA so that a nominal voltage of 3.6 volts is formed on the contacts of the element.

Analogs and what can be replaced

The use of analogues makes it possible to restore the operability of an electric device when it is not possible to purchase an original product. For ER26500, a similar "substitute" is the element SL-2770 / T.

This battery not only fully matches the original in voltage and size, but also has the same power, so the owner of a portable device will not notice the changes.

You can replace the standard product with the LS 26500 cell. Such a battery is already only 0.2 mm in diameter, so it is ideal in the ER26500 installation compartment. The capacity of this analog is less than about 800 mA / h, but this value is only about 10% of the nominal, so it will not affect the life of the element too much.

Note! A similar size is used for type C batteries and the LM26500, but the former has a voltage of 1.5 V and the latter has 3 volts rather than 3.6, so this analogue is not always acceptable to use.

Scope of the battery

A battery of this type is used in devices whose operation is continuous, while the current consumption, as a rule, does not exceed several milliamps. Such devices include:

• Gas meters
• Elements of fire alarm.
• Medical devices.
• Motion sensors.

26500 batteries can also be used in more powerful devices, but in this case, the battery life will decrease dramatically. The battery can be discharged in a pulsed mode with a current strength of not more than 400 mA.

How to charge an element

The lithium-ion battery ER26500 is not a battery, so it will not be possible to restore the product’s performance after a complete exhaustion of the power supply. Attempts to restore capacity with the help of network chargers can end very poorly.

Lithium compounds can react with atmospheric oxygen to form an open flame; therefore, extending the life of a product by physical action on its body is also not a safe measure.

Popular manufacturers and their features

The purchase of products from popular manufacturers allows you not to be distracted by comparative tests, because companies that care about their reputation sell only high-quality products. The following well-known electronics manufacturers are involved in the release of ER 26500:

1. Saft.
2. Robiton
3. Minamoto.

A high-quality analogue of the SL-2770 / T is also manufactured by Tadiran Batteries.

What to look for when purchasing

When buying, you should carefully study the product labeling. Many batteries have the same shape, but vary significantly in voltage.

The capacity designation is not always indicated on the batteries, but if there is information on this parameter, you should choose the maximum value, even if the cost of such a product will be much higher.
