Three-pack 9 V NiMH batteries
This pack contains three 9-volt NiMH cells rated at 220 mAh each. They arrive pre-charged and hold about 85 percent of their capacity after a year in storage. The low-discharge chemistry makes them suitable for devices that sit idle for long periods. They replace standard 9-volt alkaline cells in any compatible product.
Drop-in replacement with no memory effect
Installation is a simple battery swap because the cells share the standard 9-volt form factor and 8.4-volt nominal output. No memory effect means they can be topped up at any state of charge without reducing usable capacity. The only common issue is attempting to charge them with a charger not designed for NiMH chemistry, which can shorten their service life.
Best for low-drain devices needing long shelf life
These suit smoke detectors, wireless microphones, test instruments and similar gear that draw little current but must work reliably after months on the shelf. They are not intended for high-drain applications that demand sustained heavy current. Users needing higher capacity per cell or a different voltage should look at other chemistries or form factors.

Questions about this item
How can I confirm the 9V AccuLoop batteries are holding charge after the first few recharge cycles?
The NiMH chemistry has no memory effect and is rated for up to 1000 cycles, so capacity should stay consistent through repeated use.
What comes in the package and is a charger included?
The pack contains three 9 Volt AccuLoop NiMH cells at 220 mAh each; they arrive pre-charged and ready to use.
When should I choose the 220 mAh 9 Volt version over other capacities?
Select this 8.4 Volt, 220 mAh option for devices that require a standard 9 Volt form factor and benefit from low self-discharge, retaining 85% charge after a year in storage.
