CR2330 Battery Equivalent

Key Takeaways

· CR2330 batteries are non-rechargeable, 3V lithium coin cells.

· Direct replacements must match voltage, size, and chemistry.

· Some equivalents use alternate chemistry (e.g., BR series) and may perform differently under specific conditions.

Most Common Direct Replacements

· DL2330 – Duracell equivalent

· ECR2330 – Energizer equivalent

· BR2330 – Panasonic (with lithium-carbon monofluoride chemistry)

· LIR2330 – Rechargeable version (Li-ion, 3.6V – not a direct drop-in)

Comparison Table

Model	Chemistry	Voltage	Capacity	Notes
CR2330	LiMnO?	3.0V	220–280 mAh	Standard; ideal for most electronics
DL2330	LiMnO?	3.0V	~250 mAh	Duracell-branded direct replacement
ECR2330	LiMnO?	3.0V	~250 mAh	Energizer-branded alternative
BR2330	Li(CF)x	3.0V	~200 mAh	Longer shelf life, better at high temps
LIR2330	Lithium-ion	3.6V	~50–60 mAh	Rechargeable; NOT a direct substitute

FAQ

Q1: Is CR2330 rechargeable?
No. CR2330 is a primary lithium battery and not rechargeable. Using it in a charger is dangerous.

Q2: Can I use CR2325 or CR2032 instead?
Only if your device supports the slight size and capacity differences. CR2330 is thicker than CR2325 and wider than CR2032.

Q3: What is the difference between CR2330 and BR2330?
BR2330 uses a different lithium chemistry (LiCFx) and performs better at extreme temperatures but has slightly lower capacity.

Q4: How long does a CR2330 last in typical devices?
Between 1 to 5 years, depending on the device’s power consumption and usage frequency.

Q5: Where can I buy CR2330 batteries?
Available at electronics stores, online marketplaces (Amazon, Digi-Key, Mouser), and battery specialists.
