Duracell rechargeable batteries mah8/6/2023 For ease, I’ve listed the link for four batteries. Latest dealsĭuracell sells these batteries in packs of four, eight, 12 or 16, although the price per battery is similar across pack sizes. That makes them suitable for high-drain use, in items such as powerful torches and remote control kids toys. The tested capacity was higher than the rated capacity every time, showing the quality of the Duracell Rechargeable AA 2500mAh. As you can see from the graph, the batteries held up well, with little variance between the starting and ending charges. I then charged and discharged the batteries 50 times, taking measurements every 10 cycles. Duracell AA 2500 mAh 1.2 V Pack of 4 Rechargeable Batteries - Black/Copper. Initially, the charge was 2795mAh, which is a good deal higher than the rated capacity of the batteries. Buy Duracell Rechargeable Batteries and get the best deals at the lowest. Next, I measured the capacity of the batteries using a high-drain test (600mA +/-20%, with a cut-off voltage of 0.94V). Voltage drops as the batteries are emptied of charge, although the voltage drop is lower for rechargeable batteries than alkaline non-rechargeable units. The Duracell Rechargeable AA 2500mAh measured in at 1.29V, which is a good starting point. First, I measured the starting voltage, which should be at least 1.2V for NiMH batteries. To test the batteries, I used an Ansmann Energy XC3000 battery tester. To compare, the GP ReCyko Charge 10 batteries only last 250 cycles when fast-charged, although they’ll last for 700 cycles if slow-charged. Given the price and that these are standard rechargeable batteries, that’s a decent number. This makes these units suitable for charging and leaving in a drawer, and even for lower-drain use in devices such as remote controls and clocks.ĭuracell says that these batteries can last for 400 recharges. These are low self-discharge batteries, which means that they’ll keep up to 80% of their charge over 12 months. Duracell Duralock AAA batteries are high quality nickel-metal hydride batteries. The Duracell Rechargeable AA 2500mAh performs well on all fronts, starting with a high overall capacity of 2500mAh. Duracell Duralock AAA 800mAh Pre-Charged Rechargeable Batteries (4 Pack). When it comes to standard NiMH rechargeable batteries, there are three things that you need to consider: the total number of charge cycles, their capacity, and how long they stay charged for. Well priced and offering a decent number of recharge cycles for entry-level batteries, these are a great choice if you need power and convenience. Perhaps better known for its disposable batteries, the Duracell Rechargeable AA 2500mAh batteries show that the company can also turn its hand to rechargeables. Cycles You can recharge these batteries up to 400 times.Type These are NiMH rechargeable AA batteries.As you can see from the graph below, the results were consistently around 700mAh – bar the final cycle, which topped out at 800mAh. To measure longevity, I charged and discharged the batteries 50 times, taking a capacity reading every 10 cycles. Most batteries that I test score higher than the rating printed on the side of the battery itself. Here, I found that the initial capacity was 732mAh, which is just below the rated capacity. Next, I measured capacity using a high-drain test (600mA +/-20% with a cut-off voltage of 0.94V). First, I started by measuring voltage, which should be a minimum of 1.2V the result of 1.24V is just within. To see how well these batteries performed, I ran them through a set of standard tests using an Ansmann Energy XC3000 battery tester. Plus, if you use them in low-drain devices such as remote controls, you won’t lose a lot of power each day. That’s useful, as you can charge and store them, on standby for when you want to use them. Even so, that isn’t great – even the Amazon Basics Rechargeable AAA 800mAh last for 1000 recharges.Īs is the case with most other modern rechargeable batteries, the Duracell Rechargeable AAA 750mAh will retain up to 80% of their charge after 12 months. Head to the official site, and it says that the batteries will last for three years or 400 recharges. All of the official imagery shows that these batteries can last for 100 charges, which sounds poor. Longevity is important for rechargeable batteries, but the Duracell Rechargeable AAA 750mAh offer a relatively low number of charge cycles. Image Credit (Trusted Reviews) Design and Charges The Duracell Rechargeable AAA 750mAh aren’t quite as good: mid-level capacity and a relatively low number of charge cycles mean that the competition performs better. Just about the biggest name in batteries, Duracell has impressed with its Rechargeable AA batteries.
