Allmax AA NiMH Rechargeable Batteries maintain a nominal voltage of 1.2 volts. They are also a suitable replacement for any device that uses a 1.5 volt battery, as the 1.2 volt NiMH rechargeable battery is fully compatible.
- What is the measured capacity of Allmax AA NiMH Rechargeable Batteries?
Allmax engineers have rigorously tested our rechargeable batteries, and the results demonstrate an impressive capacity exceeding 2000mAh. In contrast, numerous other brands often fall short of their labeled or claimed capacities, with some even registering substantially lower test capacities. When testing Allmax, the actual test capacity consistently matches or surpasses the marked capacity on the battery. For those seeking to compare the capacities of various rechargeable battery brands, we recommend not to rely solely on the labeled capacity. Instead, we recommend using a charger with the capability to measure the actual capacity, which will give you a more accurate representation of each battery’s true capacity for a better comparison.
- Where can I find the manufacture date?
You can find the manufacture date on the battery. The label format is MFD(date). So, for example, if the manufacture date is “MFD1122,” the battery was produced in November 2022. Allmax batteries are always considered “fresh” because they are made to order and they are packed and delivered with care to maximize the freshness and quality of the batteries.
- Are Allmax rechargeable batteries considered “low self-discharge”?
