LR44 Battery Specifications
The size. The diameter is 11.6 mm, the height is 5.4 mm.- The form. The battery has a cylindrical shape and is flat, so it is somewhat reminiscent of a tablet or coin. The shape can be called flattened and round.
- Marking. The letter combination LR indicates that it is an alkaline battery. The numerical value 44 indicates specific dimensions.
- Power. The current strength is 0.22 mA.
- Capacity. The operation time of the element depends on this designation. Capacity within ~ 160 mA / h.
- Voltage. In this case, the indicator is within 1.5 volts. If the battery is replaced with an analogue of AG13, the difference will be about 0.05 volts. Such an error is not considered critical.
- Composition. The battery contains the following components: rods, alkalis, metal housing, anode, cathode, walls with insulation.
- Weight. It is 1.95 g.

Battery Analogs LR44
It has a large number of analogues available to customers on the free market. One of the most common is LR1154. The list of replacement options is as follows:
Any of the presented analogues is perfect.
Battery Applications
Suitable for many appliances and devices. In particular, it is used for work: computer mice, keyboards, calculators, remote controls, watches, key rings, toys, laser pointers, tamogochi and thermometers.
Sometimes they can be found in medical equipment, GPS systems and portable translators. Therefore, this battery is very popular among buyers.
Can I charge the lr44 battery
It is not a battery, therefore it cannot be charged. However, some folk “craftsmen” advise charging with heating, a homemade charger, or standard telephone charging.
Attention! The procedures outlined above are highly questionable, as the LR44 product may explode when heated. Others may be injured. Therefore, do not risk it.
Popular manufacturers and their features
Mostly batteries of the LR44 type are made in China, for example, Videx. Also, many well-known companies, in particular Panasonic, Sony and many others, are engaged in the manufacture of popular power supplies. Products of the following well-known brands are quite affordable: Duracell, Camelion, Varta, Energizer, Renata, GP, Maxell and Cosmos.
What is the difference between the LR44 battery and the analogues on the market today? It consists in the use of various substances and materials in production.
For example, the SR44 is a zinc-silver element, so it costs slightly more than the battery presented. Also, its capacity is 150 mA / h, so the operating time will be slightly longer than that of the LR44.
What to look for when purchasing
Many people at the time of buying batteries do not pay absolutely no attention to the expiration date, labels, drawings, manufacturer. Most often, they are interested in the size, as well as the amount that is necessary for the functioning of the device / device.
When purchasing batteries, you should definitely look at the expiration date. It is important to take into account the production date. Even alkaline battery LR44 was in a cold warehouse for six months, then its performance will decrease and will be less than 100 percent.
Attention! When choosing, you should pay attention to the manufacturer. It is clear that the products of well-known brands will work much better and longer than cheap Chinese counterparts.
You should not purchase expensive items for devices that are characterized by low power consumption. Also, you do not need to take cheap products for "gluttonous" devices. Purchasing batteries with a margin should also not be done, as long-term storage, especially at low temperatures, can not be expected from LR44 for extended periods of time.
