LR44 battery equivalents are also referred to as A76, AG13, L1154, LR1154, 157. These sizes are possible LR44 battery replacements. There are other batteries that are similar to the LR44 battery but are different in composition chemistry.
AG13/LR44/SR44/SR44SW/357 button/coin cell batteries are very popular batteries, commonly found in wrist watches, small flashlights, calculators, some remote control devices, thermometers, laser pointers, and other small electronic units.
According to the IEC standard, this battery should be called LR1154 (alkaline) or SR1154 (silver-oxide). Sometimes shorter, two-digit code is used: LR44 for alkaline and SR44 (or SR44SW) for silver-oxide batteries.
Many manufacturers use their own names for these batteries, but they also tend to add IEC and other standard codes, including short descriptions about the chemistry and other important features.
LR44/LR1154 (alkaline) or SR44/SR1154 (silver-oxide) batteries are button/coin cell batteries 11.6 mm in diameter and 5.4 mm in height. Their capacity depends on the used chemistry, but also on the cut-off voltage of the used device.
Few notes:
- AG13 vs SG13: AG13 should be 'alkaline G13' and SG13 should be 'silver-oxide G13' battery. However, sometimes manufacturers mark silver-oxide batteries with both SG13 (correct) and AG13 (not so correct) to emphasize that their battery is a replacement for AG13/LR44/LR1154 battery.
- if the battery code starts with the 'L', then it is most probably an alkaline coin cell.
- if the battery code starts with the 'S', then it is a silver oxide coin cell.
- if the battery code starts with the 'P', then it is a zinc-air coin cell.
- if the battery code starts with the 'M' or 'N', then it is a mercury-oxide coin cell. However, due to the presence of mercury, these batteries are no longer in use.
- if the battery code after the digits contains 'P', then it is the battery with potassium hydroxide electrolyte.
- if the battery code after the digits contains 'S', then it is the battery with sodium hydroxide electrolyte.

Bro After replacing my battery My calculator doesnt turn on it glows in sunlight and shows battery low

It's possible that there could be a problem with the battery contacts in your calculator. Sometimes, corrosion or dirt can prevent the battery from making good contact with the terminals. You can try cleaning the battery contacts with a cotton swab and some rubbing alcohol.
If that doesn't work, there may be a more significant issue with the internal circuitry of the calculator

bettary name ki???

[@TonaziTube]

LR44/LR1154 (alkaline) or SR44/SR1154 (silver-oxide) batteries is called button/coin cell batteries
