The Open Circuit Voltage (no load voltage) of the 1.5V AA Duracell Alkaline batteries is 1.6V, though it quickly drops to 1.5V under load. Once I was in Radio Shack and a customer came in to buy replacements for four "dead" batteries. Size: AA (LR6) Alkaline-Manganese Dioxide Battery Berkshire Corporate Park Bethel, CT. 06801 U.S.A. Telephone: Toll-free 1-800-544-5454 www.duracell.com Delivered capacity is dependent on the applied load, operating temperature and cut-off voltage. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type. 2. This is intended as a guide only as the voltage reading will be effected by the battery age, technology and temperature. The above chart gives an indication of what the voltage should be at different states of charge and operating conditions. Voltage vs. temperature of Energizer Lithium Ultimate AA batteries. Sometimes a battery will be useless for certain high-power devices (e.g. AA batteries have about three times the capacity of AAA batteries. The advantage of rechargeable batteries is that they can be recharged and reused up to a thousand times and generally they greatly outperform standard everyday throwaway leading brand batteries. If the discharged battery voltage is less than 1.0 Volts/cell start with a C/10 charge. New Batteries are purchased from a retailer to make sure they are fresh. This page describes various battery types for classic and contemporary cameras, including full specifications for various battery types (dimensions, voltage, common uses, etc.). The average alkaline battery has a voltage of 1.5V. 2. The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application. Variables . These batteries were the best because of their ample capacity, size, and voltage. Designation: ANSI 15-LF, IEC-FR14505 (FR6) Nominal Voltage: 1.5 Volts Sizing Compatibility Storage Temp:-40°C to 60°C (-40°F to 140°F) Operating Temp:-40°C to 60°C (-40°F to 140°F)* Typical Weight: 15 grams (0.5 oz.) AAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. A lead-acid car battery will output 12V. Imagine the batteries shown in the diagram are rated at 1.5 volts and 500 milliamp-hours. Phil, I have a Battery Monitor who's Red LED will light up IF the battery gets to 12.00 Volt, I've simply tapped into that circuit sending it to a Change Over Relay which will then cut off the power to preserve the batteries. A nickel metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery.The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). A low voltage cut-off circuit prevents over discharge. Alkaline batteries are available in different sizes, classified as AA, AA-, AAA and so on. 3. By default the test results are sorted with the highest capacity in mAh first, going down to the lowest capacity in the end. However when it’s placed under load, the voltage comes in at ~ 1.5 volts. Table 1 . Eneloop AA BK-3MCCE 1900mAh (White) 2019 Official specifications: Nominal voltage: 1.2V Minimum capacity: 1900mAh Low self discharge: 70% capacity left after 10 years Cycle life: 2100 cycles. We are testing all Alkaline batteries with a constant current load of 0.1A, 0.2A, 0.5A and 1A and measuring what capacity they can provide at these levels, and these Alkaline cells from Duracell are no exception. The table below shows the battery volume for cell sizes AAA, AA, C, and D. The volume does not change with the type of battery, but the weight does, as shown here. Energizer Lithium Battery L91 (AA form factor) Voltage Discharge Profile. An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. An Alkaline Fujitsu battery has a capacity of 2258mAh, while an eneloop can provide 1859mAh according to HKJ`s tests. Variables. Camera Batteries - a complete chart. I just purchased a Sony 10W Halogen video light that runs from four AA size Ni-Mh cells. For regular camera batteries, I also have pricing information below from several local and retail vendors. A battery's chemistry will also affect the nominal voltage that it will produce. AA: 2400 : 50: AAA: 1000: 10: N: 650 : 10 : 9 Volt: 500: 15: 6 Volt Lantern: 11000: 300: The battery capacity will be better with lower drain currents. The nominal voltage of a battery depends on the chemical reaction behind it. We can explain the wide fluctuations in voltage over time by considering figure 3 that compares the above with temperature data… also transmitted by the MT-2001. Their specifications enabled them to be one of the most used batteries.
