Key Specifications

The essentials, at a glance:

• Capacity – 750 mAh (≈2.8 Wh)
• Nominal Voltage – 3.7 V (Li-ion)
• Form Factor – 14500 (≈Ø14 mm × 50 mm)
• Chemistry – Lithium-ion (rechargeable)

Compatibility

Where it works best:

• Designed for devices that specifically support 14500 Li-ion (3.6/3.7 V) cells
• Not interchangeable with standard 1.5 V AA unless your device explicitly allows 14500 use
• Typical uses – compact flashlights, tools, and electronics rated for Li-ion AA-size cells

Safety & Handling

Good practice for long life and safe operation:

• Use an appropriate Li-ion charger (CC/CV to 4.2 V). Do not use NiMH/alkaline chargers.
• Observe polarity and never short-circuit, crush, or incinerate.
• Store cool and dry, ideally ~30–60% state of charge if unused for long periods.

Storage & Operating

Keep performance steady with sensible conditions:

• Avoid extreme temperatures during use/charge/storage
• Charge supervision – do not charge unattended

Energy Management

How to get the best from your cell:

• No memory effect – partial charges are fine
• Low self-discharge – maintains charge well when stored correctly
• Top up regularly rather than deep-discharging

Rechargeable

By using rechargeable batteries, you're not just protecting your wallet, but also the environment. Regular batteries, after all, require up to 500 times more electricity to produce than they can release themselves. Combined with the energy consumption for transport and storage, the CO₂ emissions are huge.
