CR11108, CR1/3N, CR-1/3N, DL1/3N, 2L76, 2LR44 3V Lithium Non-Rechargeable Battery Equivalents and Replacements
CR11108, CR1/3N, CR-1/3N, DL1/3N, 2L76, 2LR44, 2KL1/3N, 5008L, VL1/3N, etc. are non-rechargeable 3V lithium batteries, most commonly based on the Lithium Manganese Dioxide chemistry.
Commonly, they are known as CR11108 or CR1/3N batteries and are often used in cameras, calculators, dog collars, gun sights, PDAs, computer motherboards, etc.

As its name suggests, CR11108 battery dimensions are 11.6 mm in diameter and 10.8 mm in height.
Also, its common labels include:
- CR1/3N or CR-1/3N, because the CR11108 battery is 1/3 in height of the N battery, which is 12 mm in diameter and 32 mm in height.
- 2L76 or 2LR44, because the CR11108 battery is double in height of the SR44SW/LR44/L76/357 battery, which is 11.6 mm in diameter and 5.4 mm in height.
CR11108 or CR1/3N batteries are lithium non-rechargeable 3V batteries, featuring lithium negative electrode, with the positive electrode being commonly manganese-dioxide or rarely carbon-monofluoride.
Manganese-dioxide lithium batteries come with labels that start with the 'C' letter.
Generally, their operating temperature range is between -20°C (-4°F) and 70°C (158°F), the nominal voltage is 3.0 V, and the cutoff voltage is 2.0 V, with a typical capacity of 160-170 mAh and a shelf life of 5-10 years, depending on the storage temperature.
The typical labels are CR11108, CR1/3N, CR-1/3N, DL1/3N, 2L76, 2LR44, 2KL1/3N, 5008L, VL1/3N, etc. battery.
Carbon-monofluoride lithium batteries of this size are rare, and their label is BR11108 or BR1/3N.
Note: some manufacturers use 'BR11108' or 'BR1/3N' when labeling their manganese-dioxide lithium batteries in order to emphasize that their manganese-dioxide lithium batteries are equivalent to the carbon-monofluoride lithium batteries of the same size - and that is mostly correct.
CR11108 or CR1/3N Similar Batteries
As said before, CR11108 labels 'CR1/3N' and '2L76' come from the fact that the CR11108 battery is 1/3 of the N battery height, and that it is double the height of the SR44SW/LR44/L76 battery.
Also:
- one CR11108 battery can be replaced in certain devices with 2 individual SR44SW/LR44/L76 batteries, preferably using silver-oxide chemistry. Such a combination features a nominal voltage of 3.1 volts, a cutoff voltage of 2.4 volts, and a capacity in the 150-200 mAh range.
- two CR11108 batteries can replace one 6 volts battery labeled as 2CR1/3N or 2CR11108 which is often used in digital cameras, game controllers, shavers, and similar.
- three CR11108 batteries can replace 9 volts battery labeled as an 'N-Cell' battery. Also, labels like 3CR1/3N or 3CR11108 are often used to emphasize that such battery is 9 volts N-cell battery.

Of course, there are many more CR11108 battery models on the market, so choose according to your own needs and preferences.
CR11108, CR1/3N Battery Safety Issues
Modern CR11108 batteries don't contain heavy elements like lead, mercury, and cadmium, but they are small, shiny objects that may appear attractive to pets and kids.
If a CR1108 battery or any similar battery gets swallowed, it can cause chemical burns in the body due to the electrolytic processes - body fluids short-circuit the battery and chemical reactions start.
If a battery gets swallowed, contact the nearest emergency center, explain to them what has happened, and act according to their instructions.
