Three rectangular 9 V lithium-ion batteries, blue wrap, 17.8 by 26.8 by 49.2 mm

DUSLAN

DUSLAN 9 V Lithium-Ion Battery 500 mAh 3-Pack

SKU CH-KQBW-YEW3P

Three 9 V lithium-ion cells deliver 500 mAh each, recharge up to 700 times and include built-in PCB protection

  • Battery Type9 Volt
  • Up to 700 recharge cycles per battery
  • 500 mAh capacity for long-lasting power
  • Less than 10 % monthly self-discharge
  • Built-in PCB prevents overcharge and over-discharge
  • Dimensions 17.8 mm × 26.8 mm × 49.2 mm fit most compartments

What you get

This pack contains three 9 Volt lithium-ion rechargeable batteries, each rated at 500 mAh. They are intended for any device that accepts a standard 9 Volt cell and where the compartment can accommodate the slightly larger dimensions. The cells ship new and ready to charge with the required lithium-ion charger.

Critical fit check

Each cell measures 17.8 mm thick, 26.8 mm wide and 49.2 mm high, making it larger than a typical NiMH 9 Volt battery. Verify the battery compartment dimensions before purchase; the pack will not fit in tighter slots designed only for the smaller form factor.

Sustained use profile

The chemistry shows minimal self-discharge, below 10 percent per month, so stored cells retain usable charge for long periods. Rated for up to 700 recharge cycles with the dedicated charger, the pack delivers consistent voltage through repeated deep-use sessions without the memory effect that degrades older chemistries.

Highlights

  • Less than 10 % monthly self-discharge
  • Built-in PCB prevents overcharge and over-discharge
  • Dimensions 17.8 mm × 26.8 mm × 49.2 mm fit most compartments

Questions about this item

How long will the 500 mAh capacity run a typical device before needing a recharge?

At 500 mAh the pack delivers roughly half an ampere for one hour; actual run-time depends on the current draw of the device you power.

What charging standard does the built-in PCB require?

The PCB only works with the matching lithium-ion charger; a standard 9 V NiMH charger must not be used because it can cause the battery to explode.

Will the 17.8 mm thickness fit my existing 9 V battery compartment?

The cell measures 17.8 mm thick, 26.8 mm wide and 49.2 mm high — slightly larger than many NiMH 9 V cells, so verify the compartment dimensions before purchase.
