DUSLAN

DUSLAN 9 Volt Lithium Ion Battery 500 mAh

SKU CH-396D-WABQY

Rechargeable 9 V lithium-ion cell delivering 500 mAh for up to 700 cycles with built-in protection PCB

  • Battery type9 V
  • Delivers 500 mAh capacity for extended device runtime
  • Recharges up to 700 cycles reducing replacement costs
  • Built-in PCB protects against overcharging and over-discharging
  • Minimal self-discharge below 10 percent per month retains charge
  • Compact 17.8 mm thickness fits standard 9 Volt compartments

Power and capacity

The DUSLAN 9 Volt Lithium Ion Battery delivers 500 mAh of rechargeable capacity for devices that require a standard 9 Volt cell. It suits users who want a long-lasting alternative to disposable alkaline batteries in compatible electronics.

Dimensions and charging requirements

The cell measures 17.8 mm thick, 26.8 mm wide and 49.2 mm high, making it slightly larger than typical NiMH 9 Volt rechargeables. Buyers must verify that their battery compartment can accommodate this size before purchase. A dedicated Li-ion charger is required; using a NiMH charger may cause the battery to explode. Charging takes about 1 hour.

Cycle life and self-discharge

The built-in PCB protects against overcharging and over-discharging, supporting up to 700 recharge cycles with minimal memory effect. Self-discharge stays below 10 per cent per month, so the cell holds its charge during storage. It is not suited for devices that cannot accept the larger form factor or for users without the correct Li-ion charger.

Questions about this item

How do I install the DUSLAN 9 Volt Lithium Ion Battery and what size check prevents a fit issue?

Insert the battery into the device's 9 V compartment, observing the marked polarity. The cell measures 17.8 mm thick, 26.8 mm wide and 49.2 mm high — slightly larger than a standard 9 V NiMH — so verify the compartment dimensions before closing the cover.

What replacement schedule should I expect for the DUSLAN 9 Volt Lithium Ion Battery?

The pack is rated for up to 700 charge cycles. With minimal self-discharge under 10 % per month and no memory effect, capacity will gradually fade after hundreds of cycles; plan to replace the cell once run-time no longer meets the device's needs.

What is the first limitation I will hit when using the DUSLAN 9 Volt Lithium Ion Battery continuously?

The 500 mAh capacity sets the runtime ceiling. Under sustained load the cell will deplete in roughly one hour and requires the dedicated Li-ion charger — about one hour to recharge — because a NiMH charger can cause the battery to explode.
