Accupower 9 V NiMH 300 mAh 12-pack standard battery

SKU CH-6VN3-SE7TJ

A 12-pack of 9 V NiMH rechargeable cells delivering 300 mAh at 8.4 V and rated for up to 1000 charge cycles

  • Battery type9 V
  • 12-pack keeps devices powered longer with 300 mAh capacity
  • NiMH chemistry delivers 8.4 V output for compatible 9 V electronics
  • Rechargeable up to 1000 cycles reduces replacement frequency
  • No memory effect maintains full capacity through repeated charges
  • Direct alkaline replacement saves money across all 9 V devices

12-pack 9 V NiMH cells for everyday devices

This pack contains twelve 9-volt nickel-metal hydride batteries rated at 300 mAh each. They suit smoke detectors, wireless microphones, multimeters and other equipment that accepts a standard 9 V cell. The chemistry avoids memory effect so partial recharges do not reduce usable capacity.

Practical limits of 8.4 V NiMH chemistry

Each cell delivers a nominal 8.4 volts, lower than the 9 volts of primary alkaline types. Some devices with strict voltage thresholds may show a low-battery warning sooner or shut down earlier. The 300 mAh capacity suits low-drain or intermittent use; high-drain applications will deplete the charge quickly.

Simple drop-in replacement with cycle awareness

Installation is a direct swap for any 9 V battery compartment — no adapters or soldering required. The cells are rated for up to 1000 recharge cycles when charged with a compatible NiMH charger. Users must ensure their charger supports 9 V NiMH chemistry; alkaline-only chargers will not work and can damage the cells.

Questions about this item

Should I choose the 12-pack or a smaller quantity?

The listing supplies exactly 12 batteries; no smaller pack is offered in this product.

What does the 300 mAh rating mean in a real device?

It delivers 8.4 volts and 300 milliampere-hours per cell, so runtime depends entirely on the current your device draws.

Does the NiMH chemistry limit the charging standard I can use?

These are standard NiMH 9 V cells that accept any compatible NiMH charger and support up to 1000 recharge cycles.
