Model: R6P (international standard model for AA carbon zinc batteries; also known as LR6P in some regions, but R6P is the most common designation for carbon zinc type).
Battery Type: Primary carbon zinc battery (non-rechargeable), zinc-manganese dry battery.
Nominal Voltage: 1.5V DC (stable voltage output under normal discharge conditions, consistent with standard AA batteries).
Open-Circuit Voltage: 1.60-1.70V DC (no-load voltage, measured without connecting external devices).
Size: Standard AA (5th) size, diameter 14.0 ± 0.5mm, height 50.0 ± 0.5mm, compatible with all devices designed for AA batteries.
Weight: 18-22g (varies with brand and material, usually around 20g).
Shelf Life: 2-3 years (under standard storage conditions: 25℃, relative humidity 50%, away from direct sunlight and high temperature).
Nominal Capacity: 800-1200mAh (at 25℃, discharge current 0.1A, cut-off voltage 0.9V; capacity decreases with the increase of discharge current).
Internal Resistance: 50-100mΩ (at 25℃, new battery; internal resistance increases with discharge and storage time).
Operating Temperature Range: -10℃ to 40℃ (optimal operating temperature: 15℃-25℃; performance degrades significantly beyond this range).
Self-Discharge Rate: ≤10% per year (at 25℃; self-discharge accelerates in high temperature and high humidity environments).
Leakage Rate: ≤0.1% (qualified products under normal use and storage conditions; leakage may occur if used or stored improperly).
Low-Current Discharge (0.05-0.2A): This is the optimal discharge current range for R6P batteries, which is consistent with the power consumption of most low-power devices (such as remote controls, wall clocks). Under this condition, the battery can release nearly 100% of its nominal capacity, the voltage drops stably, and the service life is long. For example, when discharged at 0.1A, the discharge time can reach 8-12 hours (depending on the nominal capacity).
Medium-Current Discharge (0.2-0.5A): Under medium-current discharge, the discharge capacity of the R6P battery decreases by 20%-30% compared with low-current discharge. The voltage drops faster, and the service life is shortened. It is suitable for devices with moderate power consumption (such as small flashlights, portable radios), but it is not recommended for long-term use.
High-Current Discharge (＞0.5A): The R6P battery has poor performance under high-current discharge. The discharge capacity is only 50%-70% of the nominal capacity, the voltage drops sharply, and the battery may overheat. It is not suitable for high-power devices (such as digital cameras, high-speed remote-controlled toys), as it will not only fail to meet the power demand but also reduce the battery life.
Optimal Temperature (15℃-25℃): The electrochemical reaction of the battery is the most stable, the discharge capacity and voltage stability reach the best state, and the service life is the longest.
Low Temperature (＜-10℃): The viscosity of the electrolyte increases, the ion transmission speed slows down, the activity of the electrode active substances decreases, the discharge capacity decreases by 40%-60%, and the voltage may be too low to power the device normally.
High Temperature (＞40℃): The side reaction between the electrode and the electrolyte accelerates, the self-discharge rate increases, the active substances are consumed faster, the discharge capacity decreases by 30%-50%, and the risk of battery leakage and bulging increases.
Stable Discharge Stage: In the early stage of discharge (0-50% capacity release), the voltage remains stable at around 1.4-1.5V, which can ensure the normal operation of the device.
Voltage Decline Stage: In the middle stage of discharge (50%-80% capacity release), the voltage gradually drops to 1.2-1.4V, and some sensitive devices may have slight performance degradation (such as dimmed flashlight lights).
Rapid Decline Stage: In the late stage of discharge (＞80% capacity release), the voltage drops rapidly to 0.9-1.2V (cut-off voltage), the battery is basically exhausted, and the device can no longer work normally.
Household Electronic Devices: TV remotes, air conditioner remotes, set-top box remotes, wall clocks, desk clocks, low-power LED desk lamps, electric mosquito coils, etc. These devices have low power consumption and intermittent use, which perfectly match the discharge characteristics of the R6P battery.
Office and Study Devices: Calculators, electronic dictionaries (low-power models), desk lamps (small LED models), portable scanners (low-power), etc. These devices are used for a short time each time, and the power demand is low.
Portable and Emergency Devices: Small flashlights (short-term use), portable radios, electronic thermometers, pedometers, emergency lights (backup power), smoke detectors, etc. The R6P battery is small in size, light in weight, and suitable for outdoor or emergency use.
Children’s Toys: Low-power children’s toys, such as plastic toy phones, puzzle toys with small lights, non-motorized toy cars, simulated toy cameras, etc. The low cost and high safety of the R6P battery make it suitable for children’s toys.
High-Power Electronic Devices: Digital cameras, camcorders, high-speed remote-controlled toys, portable speakers, electric tools, game controllers, etc. These devices require high current and long-term stable power supply, and the R6P battery cannot meet the demand.
Continuous High-Power Use Devices: Portable chargers, electric shavers, electric toothbrushes (high-power models), etc. These devices need continuous high-power supply, and the R6P battery will be exhausted quickly.
Sensitive Electronic Devices: Precision instruments, medical devices, electronic sensors, etc. These devices have high requirements for voltage stability, and the voltage drop of the R6P battery in the later stage of discharge may affect the normal operation of the device.
Do not recharge the battery: The R6P is a primary battery, and recharging will cause electrolyte leakage, bulging, or even explosion.
Do not mix old and new batteries or different types of batteries: Mixing will cause uneven discharge, overheating, and leakage; replace all batteries at the same time.
Install according to the positive and negative polarity: Follow the “+/-” marks in the battery compartment to avoid short circuits or device damage caused by reversed installation.
Avoid short circuits: Do not place the battery with metal objects (such as keys, coins) to prevent direct contact between the positive and negative electrodes.
Proper storage: Store in a cool, dry, and ventilated environment, away from high temperature, humidity, and direct sunlight; do not store for more than 2 years.
Proper disposal: Do not discard waste batteries randomly; dispose of them according to local waste battery recycling regulations.
