![]() ![]() In reality, internal losses turn some of the energy into heat and lower the resulting capacity to about 95 percent or less. The sum should be the same since the identical amount of energy is dispensed over a shorter time. By discharging the 1Ah battery at the faster 2C-rate, or 2A, the battery should ideally deliver the full capacity in 30 minutes. When discharging a battery with a battery analyzer capable of applying different C rates, a higher C rate will produce a lower capacity reading and vice versa. A new battery is sometimes overrated and can produce more than 100 percent capacity others are underrated and never reach 100 percent, even after priming. If the discharge lasts 30 minutes before reaching the end-of-discharge cut-off voltage, then the battery has a capacity of 50 percent. ![]() If a 1Ah battery provides 1A for one hour, an analyzer displaying the results in percentage of the nominal rating will show 100 percent. ![]() For lead acid, the end-of-discharge is typically 1.75V/cell, for NiCd/NiMH 1.0V/cell and for Li-ion 3.0V/cell. (See BU-909: Battery Test Equipment) The analyzer discharges the battery at a calibrated current while measuring the time until the end-of-discharge voltage is reached. The battery capacity, or the amount of energy a battery can hold, can be measured with a battery analyzer. Table 1: C-rate and service times when charging and discharging batteries of 1Ah (1,000mAh) Table 1 illustrates typical times at various C-rates. Some high-performance batteries can be charged and discharged above 1C with moderate stress. Losses at fast discharges reduce the discharge time and these losses also affect charge times.Ī C-rate of 1C is also known as a one-hour discharge 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. A green light means that the battery is more than 50 percent charged, a blue light means less than 50 percent, and a red light indicates less than 10 percent battery.Charge and discharge rates of a battery are governed by C-rates. Since you won’t be using a charging block, the Nitecore battery has a button you can press to gauge how much charge is left in it. Nitecore said they were able to shoot roughly 500 photos on a single charge cycle, testing it by shooting manual on a Sony a9. According to Nitecore, the UFZ100 is compatible with Sony’s a7 III, a7R III, a&R IV, a7S III, a9, a9 II, a6600, a7C, a1, FX3, and the latest a7 IV.Ĭompared to Sony’s camera batteries, the Nitecore UFZ100 has a slightly lower capacity at 2,250mAh and takes four hours to fully charge. ![]() Similar capacity - Nitecore’s UFZ100 is designed to replace Sony’s NP-FZ100 batteries, so those shooting on Nikon, Canon, Fujifilm, or any other system are still stuck with their chargers. And this way, you’ll never have to sweat losing the expensive proprietary charger ever again. With the UFZ100’s USB-C port, you’ll no longer need the blocky charger that comes with your Sony camera. ![]()
