Lithium CR2016, BR2016, LiR2016, DL2016, ECR2016, E-CR2016, SB-T11, 5000LC Battery Equivalents and Replacements
Lithium CR2016, BR2016, LiR2016, DL2016, ECR2016, E-CR2016, SB-T11, 5000LC etc battery is lithium 3.0 volts non-rechargeable button/coin cell.
It is very popular, low-profile battery commonly used in digital watches, credit-card size devices, remote controls, calculators etc.
Since practically all most reputable battery brands manufacture these batteries, getting a new one shouldn't be a problem.
However, it is good to know few additional things about these batteries ...
Lithium CR2016 Features and Specifications
Lithium CR2016, BR2016, LiR2016, DL2016, ECR2016, E-CR2016, SB-T11, 5000LC etc batteries are button/coin cell batteries featuring 20 mm (0.7874 inches) diameter and 1.6 mm (0.06299 inches) height, thus '2016' as part of their label.
Proper label for these batteries are CR2016 for manganese-dioxide lithium 2016 batteries and BR2016 for carbon-monofluoride lithium 2016 batteries.
Manganese-dioxide lithium CR2016 batteries have labels starting with the letter 'C'. Generally their operating temperature range is between -20°C (-4°F) and 70°C (158°F), with nominal voltage being 3.0 V, and a cutoff voltage is 2.0 V.
Nominal capacity CR2016 battery is ~90 mAh, with maximum discharge current of 1 mA and nominal discharge current of 0.1 mA.
Note: some manufacturers offer high- and low-drain CR2016 batteries, optimized for different purposes. Also, temperature range may differ, and there are some models with temperature range between -30°C (-22°F) to 85°C (185°F).
Carbon-monofluoride lithium CR2016 batteries have labels starting with 'B'. Generally their operating temperature range is between -30°C (-22°F) and 85°C (185°F).
Nominal voltage is 2.8 V, with a cutoff voltage of 2.25 V - they feature somewhat lower initial voltage, but their voltage is more stable.
Nominal capacity of the BR2016 battery is lower than the capacity of the CR2016 battery and ranges between 70-75 mAh. Nominal discharge current is ~0.03 mA (30 A).
Lithium-ion rechargeable LiR2016 batteries are rare to find. They feature 3.6 volts nominal voltage and nominal capacity of ~20-25 mAh.
LiR2016 are not as nearly common as CR2106 batteries - they have higher voltage (3.6 vs 3.0 volts), lower capacity and their self discharge rate is faster. But, they can be recharged 500+ times using ONLY battery chargers intended for these batteries.
Watch Battery CR2016
One of the most common uses of CR2016 battery is for powering digital watches.
As such, high-quality CR2016 batteries from reputable brands are highly recommended. As such, they commonly have shelf-file of 7-10 years, sometimes even more, wide range of operating temperatures, at least 90 mAh capacity when drained down to 2.0 volts, and are leak proof.
But, other brands are trying to establish themselves by offering good batteries at affordable prices.
CR2016 vs BR2016 vs LiR2016 Battery
Main advantages of the BR2016 batteries over CR2016 are low-self discharge rate and broader temperature range.
However, with the advances in technologies, high-quality manganese-dioxide lithium batteries ('CR' 2016 batteries) feature ~1% annual self-discharge rate and rather wide operating temperature range, coming very close to the BR2016 batteries.
Also, for devices requiring higher drain currents, BR2016 batteries are not good choice.
Thus, many manufacturers are not even producing BR2016 batteries, but they claim that their CR2016 batteries are replacements for BR2016 batteries - and they are.
With 7-10+ year shelf-life and ~90 mAh capacity, CR2016 batteries from reputable brands are proper choice when such batteries are required.
LiR2016 batteries - IMHO, although they can be recharged many times, their lower nominal capacity and voltage difference make them not very popular CR2016 battery replacement.
CR2016 vs CR2032
CR2016 and CR2032 feature the same battery diameter (20 mm), but the CR2016 feature one-half height of the CR2032 battery.
Some devices allow using two CR2016 batteries instead of one CR2032 in order to achieve higher voltage without requiring special DC-DC converters.
Devices that are powered with CR2032 batteries and they don't have explicitly written by their manufacturers that they can be powered using a pair of CR2016 instead of a single CR2032 battery, they should NOT be powered using CR2016 batteries - 6.0 vs 3.0 volts difference can easily damage sensitive electronic equipment.
DL2016 vs CR2016 vs ECR2016
Standard labels for lithium non-rechargeable '2016' batteries are CR2016, BR2016 or 5000LC, depending on the standard.
However, to make things more interesting, some manufacturers also use their own labels, for example:
- Duracell CR2016 battery is labeled as DL2016,
- Energizer CR2016 battery is labeled as ECR2016, etc.
But, practically all manufacturers also add CR2016 and other labels on the packages to inform the users that their 2016 battery is equivalent to 2016 batteries from other manufacturers as well.
CR2016 Safety Issues
Modern CR2016, BR2016, and LiR2016 batteries are made using no lead, cadmium and similar heavy metals, but, they are nonetheless dangerous when swallowed.
With 20mm diameter, they are not easy to swallow, but just in case, keep them away from kids and pets. And if something like that happens, call emergency services right away.
Although they don't contain heavy elements, they can cause electrolytic reactions in the body that may be very harmful.
Fortunately, most CR2016 and similar batteries come in 'children safe' packages, making them generally inaccessible to children. IMHO, very determine kid with scissors can open even such packages...
Long Story Short: If you are looking for CR2016 battery replacement, consider CR2016 battery from reputable brands, especially if you need it for digital watches, PDAs and similar.
They feature long shelf-life, ~90 mAh capacity when drained slowly, tolerates high-drain currents (~1m Ah, at least general purpose and high-drain models), operate well in wide temperature range etc.
