DUSLAN 9 Volt Lithium Ion Battery 500 mAh 6-Pack

SKU CH-7CD4-A1FXC

Six 9 V lithium-ion cells deliver 500 mAh each, recharge up to 700 times and hold charge with under 10 % monthly self-discharge

  • Battery Type9 Volt
  • Six-pack delivers 500 mAh each for extended runtime
  • Lithium-ion chemistry with built-in PCB prevents overcharge and over-discharge
  • Recharges up to 700 cycles for long-term value
  • Self-discharge below 10 % per month keeps power ready
  • Dimensions 17.8 mm × 26.8 mm × 49.2 mm fit most 9 V compartments

Six-pack lithium-ion 9V cells

These six 9 volt lithium-ion cells each deliver 500 mAh capacity and arrive new in a single pack. They suit devices that require a 9V form factor such as wireless microphones, medical instruments or test equipment. The chemistry eliminates memory effect and keeps self-discharge below 10 per cent per month. A built-in PCB guards against over-charge and over-discharge during every cycle.

Sustained output with protection circuit

Under continuous load the internal PCB maintains stable voltage by cutting power before the cells reach critical limits. Each battery accepts up to 700 recharge cycles when paired with the specified lithium-ion charger, which restores a full charge in roughly one hour. The protection logic prevents the voltage sag that can appear in unprotected chemistries during extended sessions. Minimal monthly self-discharge means a stored pack remains ready for weeks without top-up.

Direct alkaline replacement with size check

The pack replaces disposable alkaline 9V batteries in any device that fits the 17.8 mm thickness, 26.8 mm width and 49.2 mm height dimensions. Because the cells are slightly larger than common nickel-metal-hydride 9V packs, the battery compartment must be verified before purchase. Users who need a slimmer profile or a different chemistry should look elsewhere. The economics favour high-drain gear that would otherwise consume many alkaline cells per year.

Questions about this item

How much self-discharge should I expect from the 500 mAh lithium-ion cells if they sit unused for a month?

Self-discharge is minimal, at less than 10% per month, so the batteries retain most of their charge during storage.

What charger is required to recharge these 9 volt lithium-ion batteries safely?

You must use the dedicated Li-ion charger; a 9 V NiMH charger must never be used as it can cause the battery to explode.

Will the 17.8 mm thick cells fit in the same compartment as my older 9 V NiMH batteries?

This battery is a bit larger than regular 9 V NiMH rechargeable cells, so check your compartment dimensions before buying.
