Button cell LR44 - comparison type, data and identical replacement

LR44 batteries photo

The designation "LR44" is based on the abbreviation "LR", whereby "L" shows according to the IEC name declaration that it is an alkali-manganese cell. The "R" stands for "round cell" - what we commonly call button cell and the number 44 is part of the name according to the type IEC 1 declaration.

You don't want to read the whole article and just quickly buy a button cell that fits the LR44 battery? Then here you come to one cheap pack of 20 and here to my actual recommendation: one 2 pack with high quality silver oxide button cells (SR44)that are particularly suitable for wristwatches.

You can read below in the article why silver oxide batteries are superior to LR cells.

The LR44 battery is also sold under the names "357" and "AG13" (Photos: Sir Apfelot).

Type IEC 2 designation: LR1154

Every now and then you will find the name "LR44" next to the designation LR357 or "1154". This is the marking according to the type IEC 2 declaration, because the number 1154 means that the diameter is 11,6 mm and the height is 5,4 mm. With the IEC type 2 designation one can therefore infer the dimensions.

Incidentally, the button cells are manufactured (according to Wikipedia ) to an accuracy of a tenth of a millimeter. This results in only very small tolerances in the size of the different manufacturers.

Comparative types and alternatives to the LR44: AG13, 357 and others ...

Button cells usually have a large number of names for the same button cell, although there are no differences in size, but there are differences in chemical structure and thus in cell voltage and properties.

In principle, you can look out for the following names instead of LR44:

  • L1154
  • LR44
  • V13GA
  • AG13
  • KA76
  • LR44H
  • GPA76

The most common is the use of AG13, LR44 or 357. All of these names stand for an alkaline manganese cell measuring 11,6 mm in diameter and 5,4 mm in height.

SR cells based on silver oxide and zinc

In addition, these comparison types also function as substitutes:

  • SR1154
  • SR44
  • SR44SW
  • 303

The "SR" stands for silver oxide-zinc cell, which in my opinion is the better alternative to the "LR". The silver oxide button cells have two major advantages:

  1. they have a consistently high voltage for a long time
  2. they do not leak and are therefore suitable for use in sensitive devices such as wristwatches
There are different types in my button cell set, but each battery has the most common names. Here for example: AG13, 357 and LR44.

Buy LR44 and SR1154

If you look at Amazon for the LR44 and SR1154 button cells, you will notice that the retailers unfortunately do not take the differences very seriously. It is advertised with the designation SR44 or SR1154, although there is clearly an alkaline cell in the product and not a silver oxide battery.

For this reason I have specifically linked the individual button cells here so that you get what you are looking for:

My tip is to definitely take the SR44 from Duracell, because the silver oxide cells are leak-proof and have better electrical properties. You pay a little more for this, which is bearable given the long shelf life of the button cells.

In almost every button cell set there is also an LR44 battery - mostly with different names for this model.

LR44 button cell rechargeable?

Some button cells have rechargeable models. These then have the abbreviation "ML" or "LIR" in front of them instead of the "LR" or "SR". Unfortunately I couldn't find an ML44 or LIR44 - which would actually be the appropriate product name.

Whether the rechargeable button cells make sense is a good question anyway, because they usually have a very low capacity, so you have to charge them often. This should be quite annoying in wristwatches or remote controls, because if these devices suddenly stop working because the battery is surprisingly empty, it is always unsuitable.

LR44 / SR44 in the button cell range

If you need different types of batteries every now and then, you can look around for a button cell set. This usually also includes an LR44 / AG13 / 357 battery.

A cheap set with the LR44 is for example this one from Arcas.

I also checked whether there were button cell sets with silver oxide batteries (SR44), but unfortunately I didn't find anything here. So if you are only looking for an LR44 and want to fall back on something of high quality, you should continue to use the Duracell double pack with the SR44 to grab.
