Product Models
The rechargeable sealed Nickel Metal Hydride (NiMH) battery absorbs hydrogen in the metal alloy makeup of its negative electrode during charge. As the cell is discharged, the metal alloy releases hydrogen to form water.
The use of the metal alloy is the underlying reason for the high energy density of the NiMH cell compared to other chemistries. NiMH batteries have a long cycle life and good storage characteristics.
Frequently Asked Questions
Q1
What does NiMH stand for and how does this AA battery work?
NiMH stands for Nickel Metal Hydride. During charging, the negative electrode's metal alloy absorbs hydrogen. During discharge, the metal alloy releases that stored hydrogen to form water, generating electrical energy in the process. This chemistry enables a higher energy density compared to many other rechargeable battery types.
Q2
What is the nominal voltage and capacity of this AA NiMH battery?
This AA NiMH battery has a nominal voltage of 1.2V and a nominal capacity of 1500mAh, making it suitable for a wide range of everyday devices that require reliable and consistent power delivery.
Q3
How many times can this NiMH battery be recharged?
This battery is rated for a cycle life of ≥500 charge-discharge cycles. With proper care — such as avoiding deep over-discharge and using the recommended charge rates — you can expect consistent performance throughout its lifespan.
Q4
What are the recommended charging methods for this battery?
The standard charge rate is 150mA for 16 hours. For faster charging, a current between 750mA and 1500mA can be used. A trickle charge of 30mA to 75mA is also supported, and continuous overcharge is acceptable at 0.1C for less than 100 hours.
Q5
What are the safe operating and storage temperatures for this battery?
For standard charging, the recommended operating temperature is 0℃ to +45℃. During discharge, the battery can operate in a wider range of -20℃ to +60℃. For long-term storage, keep the battery in an environment between -20℃ and 35℃ to preserve its capacity and longevity.
Q6
What is the maximum discharge current, and what are the physical dimensions of this battery?
The maximum discharge current for this AA NiMH battery is 4500mA, with a standard discharge current of 300mA. The battery measures 14.5mm in diameter and 50.4mm in height, with a rough weight of approximately 26g — fully compatible with standard AA battery compartments.
