CR927 Battery Equivalents and Replacements
CR927 batteries are small, coin-cell types of batteries used in remote controllers, toys, watches, calculators, and similar devices and gadgets.
CR927 batteries are non-rechargeable lithium 3.0 volts batteries featuring good energy density and stable output voltage, making them a preferable choice for many micro and small electronic devices.

CR927 Battery Features and Specifications
The physical dimensions of the CR927 battery are (D x H) 9.5 x 2.7 mm (~0.3740 x 0.1063 inches). The battery features a nominal voltage of 3.0 volts, a cutoff voltage of 2.0 volts, and a nominal capacity in the 30-35 mAh range.
Actual capacity depends on the battery age, drain current, cutoff voltage of the powered device, battery temperature, and similar.
The shelf life of non-rechargeable lithium batteries depends on the storage temperature and quality of manufacture - the shelf life of CR927 batteries is usually in the 4-7 years range, with some models having even longer shelf life, up to 10 years.
CR927 batteries are based on the non-rechargeable manganese-dioxide lithium battery chemistry.
Equivalent BR927 batteries, based on the non-rechargeable carbon-monofluoride lithium battery chemistry, and LiR927 batteries, based on the rechargeable lithium-ion battery chemistry, are so rare that they are practically not in use.
The main advantage of the BR927 battery over the CR927 battery is its extra-low self-discharge rate, allowing this battery to stay operational for 10+ years, and it is typically used as CMOS/memory battery.
LiR927 battery features a nominal voltage of 3.6-3.7V and is not directly compatible with CR927 battery, but is supports hundreds of charging/discharging cycles, and in certain devices, it may prolong the period between the battery replacements.
DL927 vs. CR927 Batteries
DL927 and CR927 batteries are the same batteries - the DL927 battery is the CR927 battery manufactured by Duracell.
However, at the moment of writing this article, Duracell is NOT manufacturing CR927 batteries, and if You stumble upon the "Duracell DL927" battery, be sure to check the manufacturing date and expiration date - just in case ...

LR927/SR927 vs. CR927 Batteries
LR927/SR927 batteries are alkaline/silver-oxide 9.5 x 2.6 mm non-rechargeable batteries featuring a nominal voltage of 1.5/1.55V.
Although LR927/SR927 batteries may fit the battery compartment intended for CR927 batteries, due to the differences in voltages, these batteries are not compatible.
If the CR927 battery is replaced with LR927/SR927 battery, the device will probably not work properly, and if the LR927/SR927 battery is replaced with the CR927 battery, the device will probably be damaged.

CR927 Battery Safety Issues
Although modern CR927 batteries don't contain cadmium, lead, or mercury, they are very dangerous if swallowed - they can cause chemical burns due to the electrolytic processes they start in the body.
If CR927 or any similar battery gets swallowed, contact the nearest emergency center (or vet, if swallowed by the pet), explain to them what happened, and act according to their instructions.
CR927 battery capacity is not large, but better safe than sorry...
CR927 Battery Frequently Asked Questions
Here are some of the most common Frequently Asked Questions (FAQ) about CR927 and similar batteries.
What batteries are equivalent to CR927?
Lithium Manganese Dioxide 3.0V non-rechargeable batteries with physical dimensions of 9.5 x 2.7 mm are equivalent to CR927 batteries.
Some of these batteries are labeled as DL927, ECR927, KCR927, and similar, but they all have the same dimensions and the same battery chemistry.
Is CR927 the same as LR927?
No, the CR927 battery is Lithium Manganese Dioxide 3.0V non-rechargeable battery, while LR927 is an alkaline 1.5V non-rechargeable battery.
Although these batteries are of the same size, they are not of the same voltage, capacity, and other discharge characteristics.
Are CR927 batteries rechargeable?
No, Lithium Manganese Dioxide 3.0V batteries are NOT rechargeable.
Are CR and BR batteries interchangeable?
Yes and no. CR batteries can be used to replace BR batteries, but they feature a higher self-discharge rate and not so wide a temperature range.
On the other hand, BR batteries are unable to produce as strong current pulses as CR batteries.
So, depending on the application, CR and BR batteries may be and may not be compatible/interchangeable.
Long Story Short: CR927 batteries are not among the most popular lithium 3.0-volt batteries, and if they cannot be found at local hardware/office supply stores, they can be ordered from online shops easily.
So, if you are looking for a 3.0-volt 9.5 x 2.7 mm battery, you are most probably looking for a non-rechargeable lithium CR927 battery.
