CR1616 Battery And Its Equivalents
CR1616 battery is a lithium non-rechargeable 3.0V button/coin-cell battery, commonly used in remote controllers, car keys, credit size devices, wrist watches, as small CMOS batteries, etc.
CR1616 battery features several similar labels, all of which represent the same battery. However, there are also similar battery types that rely on different battery chemistries and having different characteristics, different enough to make them not interchangeable with CR1616 batteries.

CR1616 Battery Features and Specifications
CR1616 lithium 3.0V non-rechargeable battery is based on the Lithium Manganese Dioxide (Li-MnO2) chemistry and features physical dimensions of (D x H) 16 x 1.6 mm (~0.63 x 0.063 inches).
CR1616 battery features a nominal voltage of 3.0 volts, a cutoff voltage of 2.0 volts, and nominal capacity in the 50-60 mAh range.
Actual capacity depends on the drain current, age of the battery, battery temperature.
For example, Energizer CR1616 (Energizer CR1616 Battery Datasheet PDF) features a capacity of 60 mAh, when discharged down to 2.0 volts, over 30kΩ load @21°C.
Generally, CR1616 battery features a self-discharge rate of ~1% annually when stored at room temperatures, operating temperatures in the -30°C to +70°C range (although there are models with even broader temperature range), the typical continuous drain current of 0.1 mA, maximum continuous drain current in the 0.5-1.0 mA range, maximum pulse current up to 10 mA - all these features make CR1616 batteries a rather versatile power source.
BR1616 batteries are 3.0 volts lithium batteries based on the Lithium Carbon Monofluoride (Li-(CF)x) chemistry and they are very rare.
BR1616 batteries feature an even broader temperature range and lower self-discharge rate, but they are unable to provide pulse currents as CR1616 batteries can.
RCR1616 batteries are 3.2 - 3.7 volts lithium rechargeable batteries that are also very rare.
ECR1616, DL16161, VCR1616, and similar batteries are standard CR1616 batteries, but from different manufacturers: Energizer CR1616 - ECR1616, Varta CR1616 - VCR1616, Duracell CR1616 - DL1616, etc.
CR1616 vs CTL1616 Battery
Cobalt Titanium Lithium (CTL) batteries are rechargeable button/coin cell watch batteries, commonly used to power automatic or solar wrist watches.
CTL1616 battery features the same physical dimensions as CR1616 battery, 16 x 1.6 mm, but with several very important differences:
- CTL1616 battery is a rechargeable battery, CR1616 is NOT a rechargeable battery,
- CTL1616 features a nominal voltage of 2.3 volts, CR1616 3.0V,
- CTL1616 features a charging voltage of 2.5-2.7 volts,
- CTL1616 features a typical continuous drain current of 0.1 mA, just like the CR1616 battery,
- CTL1616 features a nominal capacity of ~12-14 mAh, CR1616 50-60 mAh, etc.
Because of all these differences, CR1616 and CTL1616 are generally NOT interchangeable.
CR1616 Battery Safety Issues
CR1616 and other similar small modern batteries don't contain mercury, lead, and other heavy metals.
However, if they get swallowed, they are very dangerous - in the human/animal body they start electrolytic processes that can cause internal chemical burns.
If CR1616 or any similar battery gets swallowed (by child, pet, or adult), contact immediately the nearest emergency center, explain to them what happen, and act according to their instructions.
Long Story Short: If You are looking for a lithium 3.0V 16 x 1.6 mm battery, go for a CR1616 battery from the most popular brands with good reviews - these also include batteries labeled as ECR1616, DL1616 and similar.
However, if the battery is labeled as CTL1616, that is a rechargeable 2.3V battery, not directly compatible with the CR1616 battery.
