LR621 Battery Specifications
The size LR621 battery is a manganese-alkaline type. The main parameters of the battery:
- Form - tablet;
- LR - manganese-alkaline element;
- Diameter - 6.8 mm;
- Height - 2.1 mm;
- Voltage - 1.5 volts;
- Nominal capacity - up to 20 mA / h;

Battery Applications
Most often, LR621 batteries are used in watches. Also, the product is installed in small flashlights, security systems, electronic scales, autonomous sensors and key rings for alarms. As a rule, icons with devices in which it is recommended to use batteries are painted without packaging.
In general, they are suitable for many mobile devices whose computer equipment requires power supplies of such capacity, size and voltage. Moreover, such elements can be completely replaced with analogues, regardless of what material is the basis of their manufacture, the main thing is that the technical parameters and dimensions are suitable.
Battery Analogs LR621
Many manufacturers manufacture such power supplies. Honestly, when you come to the store for a new battery, sometimes you get lost, making it difficult to understand what you need if there is not exactly the same element.
In fact, different manufacturers mark the goods in different ways, that is, the designation of the same batteries in capacity, power and voltage may differ. For example, for the LR621 model, the elements may well become an analogue:
Despite the different chemical composition, forms, technical characteristics of the products are the same, so they can be completely replaced with each other. It is worth noting that some power supplies with voltage may be slightly larger, not 1.5v, but 1.55v.
Note! Often, to select a battery for the desired device, it is not enough to know its parameters and technical characteristics. Therefore, when replacing it is best to take the old one with you.
Can I charge the LR621 battery
Modern power supplies for electronic and computer technology can be divided into two types - batteries and accumulators. Their main difference is that the batteries are designed for long-term use, they can be charged after they sit down, but there are no batteries.
The galvanic power supply of frame size LR621 is a battery, so it cannot be charged.
Important! Trying to charge the battery can result in serious injury.
Popular manufacturers and their features
Today, the market is literally littered with products of this type. Buy such a “coin pill” is not difficult. The production of batteries is carried out by many manufacturers:
- TM "MastAK";
- Energizer
- Maxell
- Camelion
- Renata;
- Varta;
- Space;
- GP.
There are other brands, they can be no worse.However, these have long been on the market and have proven themselves very well. Products of their production are distinguished by high operational characteristics, always correspond to the declared performance indicators. They are considered widely in demand and often bought.
What to look for when purchasing
Turning to the store for a new galvanic cell, you need to be able to choose the right power source, otherwise the device simply will not work properly. So when purchasing, you need to pay attention to:
- battery sizes;
- power (voltage);
- rated capacity;
- self-discharge level;
It is advisable to choose a product from a well-known manufacturer, even if it costs more - this is primarily a guarantee of a long service life. You also need to look at the date of manufacture of the product, the closer it is, the better the battery.
