Quick answer

For a Honeywell Dolphin CT40 Gen 1, choose a 4000mAh replacement battery from a specialist like CELLONIC. This capacity matches the original spec and provides a full shift of scanning. Look for a 3-year guarantee and fast delivery to minimize downtime.

Capacity matters for shift-long use

The Honeywell Dolphin CT40 Gen 1 originally ships with a 4000mAh battery. Replacing it with the same capacity ensures you get through a full workday without recharging. Lower-capacity options may save money upfront but can require a midday swap, which slows down warehouse or field operations.

Fit and compatibility

The CT40 Gen 1 battery is a specific shape and connector type. Not all 4000mAh batteries fit this model. When shopping, confirm the replacement is listed for the Dolphin CT40 Gen 1 (not the CT40 or CT40 XP). A direct-fit battery avoids the risk of loose connections or device damage.

Warranty and support

A longer warranty signals confidence in the battery's quality. A 3-year guarantee, like the one offered by CELLONIC, protects your investment. Also check delivery speed—if your scanner is down, fast shipping from a specialist with UK stock can get you back to work quickly.

Decision rules for buying a CT40 Gen 1 battery

  • Match capacity to original: The CT40 Gen 1 uses a 4000mAh battery. Choosing a different capacity may cause shorter runtime or fit issues. Stick with 4000mAh for reliable shift-long use.
  • Check model compatibility: Batteries for other Honeywell scanners or non-Honeywell devices (like Dyson vacuums) won't fit. Look for explicit 'CT40 Gen 1' listing. Only buy a battery labeled for the Dolphin CT40 Gen 1.
  • Prioritize warranty and delivery: A 3-year guarantee and fast shipping reduce downtime and financial risk. Specialist suppliers like subtel (since 2004) offer both. Choose a seller with a strong warranty and quick delivery.
