If you use a battery that has a voltage that is too high or too low for an electronic device, you could end up damaging the gadget or making it work poorly. The first letter of the IEC number may indicate that a new battery includes improper components even if it physically fits.
For example, the BR1225 and the CR1225 employ the same electrochemical system so that they can be used interchangeably. It is wise to know br1225 and cr1225 batteries equivalents to work in must-needed situations. Battery cross-reference charts are helpful in this instance since they ensure that the correct battery replaces the old one.
The lithium 3.0V button/coin cell batteries BR1225 and CR1225 are widely used in thermometers, keyless remotes, PDAs, hospital scales, monitoring devices, remote controls, computers, and other electronic equipment. Those who are unsure “are CR and BR batteries interchangeable or not”, should read this post because we briefly addressed the BR1225 and CR1225 batteries equivalents and replacements.
What are BR1225 and CR1225 Batteries?
The BR1225 and CR1225 batteries are nearly the same sizes as a coin. However, don’t underestimate the battery’s power, despite its coin-like appearance. So you might be thinking, ‘Is BR1225 the same as CR1225 or not?”
These two batteries have about the same physical dimensions of D 12.5 x H 2.5 mm, but they are made of different chemistry, and as a result, they function differently in terms of capacity, voltage, working temperature, self-discharge, lifespan, and other metrics. BR1225 batteries are constructed of nickel-cadmium, whilst CR1225 batteries are built of lead.
In CR1225, the first letter “C” denotes that the negative electrode is lithium, the positive electrode is manganese, and the electrolyte is organic. This non-rechargeable lithium battery has a nominal capacity of 50 mAh and a voltage of 3.0 volts with a cutoff voltage of 2.0 volts. Its maximum continuous drain current is 1mA, while its pulse current is up to 5-6mA.
According to the BR1225, the initial letter “B” denotes that the positive electrode is made of carbon monofluoride (CMF). This 3.0V non-rechargeable lithium battery has a nominal capacity of 48 mAh and a cutoff voltage of 2.0-2.25 volts, making it a good choice for low-voltage applications.
Although BR1225 batteries have a nominal voltage of 3.0 volts, the voltage in real-world applications is slightly lower but very stable. BR1225 batteries have an average drain current of 0.1 mA, with higher currents being avoided.
In both cases, “R” represents a cylindrical shape corresponding to physical dimensions. If you are interested in reading about other non-rechargeable button or coin cell batteries, such as the CR2450 batteries, which are rather popular and come in various chemistries, you may also look into it.

BR1225 VS CR1225 Batteries
BR1225 VS CR1225 batteries have identical physical dimensions; you will have no issue connecting them to their respective devices. However, each of them is still distinct, and there are certain distinctions between them that you should be aware of.
A) For starters, CR1225 batteries have a reputation for being able to withstand between -20°C (-4°F) and 70°C (158°F) temperatures. In contrast, BR1255 can withstand between -30°C (-22°F) and 85°C (185°F).
B) The BR1225 battery has a nominal voltage of 2.8 V, with a cutoff voltage of 2.25 V, whereas the CR1225 has a nominal voltage of 3.0 V and a cutoff voltage of 2.0 V.
C) CR1225 batteries are best suited for devices with high drain systems, whereas BR1225 batteries are best suited for devices with low drain systems.
D) They both have an average capacity of about 50 milliamperes (mA). However, the normal discharge current of BR1225 is between 0.03 and 0.09 mA. Its regular discharge current ranges from 0.1 to 1 milliamperes, and its maximum pulse discharge current is between 1 and 5 milliamperes.
E) Because “BR” batteries are made of different chemistry than “CR” ones, they have unique properties. BRs are designed to withstand higher temperatures than CRs.
F) The CR1225 battery is an essential part of many people’s lives. It is used in everyday products like remote controls, watches, and other items. On the other hand, BR1225 is employed in audio equipment, data collecting systems, and electronic games and clocks.
