CR2016 questions
What batteries are equivalent to the CR2016?
The CR2016 is sold as DL2016, BR2016. All of these describe the same 20 × 1.6 mm lithium cell at 3 V.
Can I use a CR2025 instead of a CR2016?
In many low-drain devices, yes — the sizes match. Check the voltage and chemistry against your device's requirement first, because a small voltage difference can matter in calibrated equipment.
How long does a CR2016 last?
A CR2016 holds a typical 85–100 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.
Is the CR2016 rechargeable?
No. The CR2016 is a single-use cell and should not be recharged.
