LR41 Battery Equivalent – find right battery

The LR41 battery is a small battery used in many small electronics, think watches, electronic books and digital thermometers.

Lr41 Battery

The Lr41 Battery measures approximately 7.9mm in diameter with a 3.6mm thickness, with a power capability from from 25 to 32mAh.

The ‘LR’ part of this battery code stands for lithium.  Generally, these lithium batteries can be replaced with silver-oxide batteries with a IEC code of ‘SR’.

Do silver oxide batteries last longer than lithium batteries?

Silver oxide batteries are generally more expensive than lithium equivalents because they last longer. Silver oxide batteries last 3-5 years, even if being used 24/7. They are typically used in low energy devices like watches.

Lithium batteries can be rechargeable and used in electronic devices that require more energy like mobile phones. With an estimated 14 billion phones in circulation, that’s an aweful lot of lithium batteries being sold to mobile phone companies.

Where does all this lithium come from for these billions of batteries?  Here’s an interesting video from Bloomberg:
