DUSLAN

DUSLAN 26650 Li-Ion 5000 mAh 3.7 V Flat Top standard battery

SKU CH-85H3-6WK4C

A 3.7 V 26650 lithium-ion cell delivers 5000 mAh capacity with a flat top terminal for high-drain devices

  • Reliable power for high-drain devices with 5000 mAh capacity
  • Consistent 3.7 V output suits many electronics
  • Up to 1000 charge cycles extends usable life
  • Flat-top 26650 form factor fits compatible holders
  • Light 80.5 g cell with 18.5 Wh energy density

26650 lithium-ion cell for high-drain devices

The DUSLAN 26650 flat-top battery delivers a nominal 3.7 V and 5000 mAh capacity in a single lithium-ion cell. It suits torches, portable instruments and custom packs that require the 26650 form factor. The flat terminal ensures reliable contact in spring-loaded or soldered holders.

Stable output with minimal self-discharge

Lithium-ion chemistry eliminates memory effect and supports up to 1000 charge cycles under normal use. Energy density reaches 18.5 Wh while the cell weighs only 80.5 g. Low internal resistance keeps voltage steady during sustained loads and the chemistry holds charge during long storage periods.

Flat-top terminal limits direct drop-in use

The 26 mm diameter by 65 mm length cell uses a flat positive terminal rather than a button top. Devices or carriers designed for button-top 26650 cells will not make contact without an adapter or soldered tab. Verify terminal style before purchase.

Questions about this item

How do I install the DUSLAN 26650 flat-top cell in a device that expects a button-top contact?

The flat-top terminal sits flush at 65 mm length; you must add a conductive spacer or solder a tab to bridge the gap to the device contact — the cell itself has no protruding button.

What replacement schedule should I expect for this 5000 mAh lithium-ion cell?

Rated for up to 1000 charge cycles; after that capacity drops noticeably, so plan to swap the 80.5 g cell once runtime falls below your needs.

What is the first limit I will hit when running this 3.7 V battery at high continuous drain?

The 18.5 Wh energy capacity depletes quickly under heavy load; voltage sag and heat appear before the 1000-cycle rating becomes relevant.
