Analogues of the 4lr44 battery for 6 v
The LR44 power supply has a relative: the 4LR44 6V power source. It also has analogs.
List of replacement options for this battery:
Thus, the 6 volt 4lr44 battery also has a large number of analogues.
Characteristics of the LR44 battery
This section presents the technical characteristics of the lr44 battery.
Dimensions of a flat battery
The LR44 battery measures 11.6 mm in diameter and approximately 5.4 mm in height.
Such battery parameters allow it to be installed in electronic devices unnoticed.
Form
What does an LR44 battery look like? It's a flat, cylindrical shape, reminiscent of a pill. You could call it a round, flattened battery.
Marking
The battery is labeled LR44. What do the letters and numbers mean? The letter marking indicates that these coin-cell batteries are alkaline. The number 44 indicates that this is a button cell of a specific size.
This table shows that LR44 is the same as AG13 or A76, etc. If there is no 44th battery available, it can be replaced with any other.
Voltage
When the need arises to purchase a power source, for example, for a watch, people ask: Which one should I buy? If I'm buying an LR44 battery, how many volts does it have?
The coin cell battery voltage is 1.5 volts. If you replace the LR44 1.5v battery with an AG 13, there may be a voltage difference of 0.05 volts. This error is not critical.
Capacity
Most often, the battery capacity determines how long it will last. CapacityThe capacity of this energy source is no more than 110 mAh.
Power
Sometimes the question arises: How many amps does an LR44 battery have? The battery is quite small, so you shouldn't expect much power.
The current strength of the LR44 battery is 0.22 mA.
How much does a button cell battery of this type weigh?
The weight of this alkaline battery is 1.95 g.
Battery composition
The lr44 battery consists of:
- Metal case
- Alkalis
- Rod
- Insulating partitions
- Anode
- Cathode
Not only tablet batteries have a similar composition, but also some others.
How to charge an LR44 battery?
Is it possible to charge an LR44 battery? Many claim it's impossible. However, there are methods that allow you to charge this mini battery.
There are three charging methods:
- A simple heating method. This can be done on a stove or with a lighter. This method is dangerous and can cause the power source to explode.
- Charge the battery using a regular phone charger. The key is to ensure the end of the cable has a round tip. It's also important to know where the "+" and "-" terminals are. Connect the cables from the charger to the corresponding terminals of the battery and hold them in your hand. If you feel any significant heat, disconnect the cable immediately. This could cause an explosion.
- Solder a simple charger according to the diagram below.
The charging tips provided are extremely dangerous and should be used at your own risk. To avoid any risks, it's best to purchase a new power source.
Charger for LR44
A diagram of a charger for IR44 batteries and similar ones was found on the Internet.
When soldered together it looks like this:
Charger circuit diagram
Charger For LR44 batteries, the charger uses KD 102B diodes, but KD 105B can be used. The maximum output current is fixed at 10 mA. The brighter the green LED, the more discharged the battery is. Recharging time ranges from 3 to 12 hours, depending on the discharge level.
Replacing the LR44 battery
LR44 batteries are easily replaceable. However, some devices require a screwdriver. Most often, the replacement process consists of several steps:
- Unscrewing the bolts
- Removing the battery compartment cover
- Removing used elements
- Installing new power supplies
- Closing the lid
- Reverse tightening of bolts.

How to test an LR44 battery using a simple test?
The video shows an analog LR44 battery tester. However, a digital version also exists.
Testing LR44 batteries with this device is quite simple! All you need to do is turn on the tester, place the power source on the platform, and press it down with a special slider. Once the contacts are connected, the voltage reading will automatically appear on the display.
This video shows how to measure the voltage of a button cell battery using a digital multimeter.
Types of LR batteries
There are 8 main species of this family:
The difference between some tablet batteries
The difference between SR44 and LR44 batteries lies in the materials and substances they are made of and much more. For example, sr44It's a silver-zinc element. It costs a little more than a 44 power supply. Plus battery capacityequals 150 mAh. This means it will last longer than the battery described above.
