Accupower 9V NiMH 300 mAh 3-pack standard battery

Three-Pack 9V NiMH for Everyday Devices

This set contains three AccuPower 9 volt nickel-metal hydride cells rated at 300 mAh. They suit household items such as smoke detectors, wireless microphones and portable meters that require a standard 9 V format. The chemistry delivers 8.4 volts nominal and can be recharged up to 1000 cycles. Buyers who need higher capacity cells or lithium primary voltage should look elsewhere.

Snap-In Format With No Memory Effect

Each battery matches the familiar rectangular 9 V footprint, so it seats directly in existing battery compartments without adapters. Nickel-metal hydride chemistry eliminates memory effect, allowing partial recharges without capacity loss. The cells hold charge reliably over repeated use. Devices that demand a full 9 V primary voltage or proprietary form factors will not be compatible.

Ready-to-Use Triple Pack

The three-cell pack lets you keep one set in service while another charges, reducing downtime for critical equipment. Recharging up to 1000 times replaces hundreds of disposable alkaline units over the service life. No charger or software is included in the package. Users without a compatible NiMH charger must purchase one separately.
