A CR2032 (disposable) has 2x-4x (200 mah under ideal conditions, compared to 40 mah) the capacity of the same sized LR2032 (rechargeable), and is more stable over a long period of time. In addition there is the necessity of additional charging circuitry, and I'm not sure how small they can physically make the charging antenna.
Lithium rechargeable would mean higher price, larger size for equivalent specs, with an added risk of fire!
- sydd 6y agoInstead now we get millions of CR2032 batteries thrown into the garbage each day :/ Anything with non-chargeable batteries is a no go from sustainability perspective
- chid 6y agoyou could get them as a re-chargeable (though it would likely be more waste to buy a recharger) - but I mean even rechargeable batteries are also consumables
- dghlsakjg 6y agoRechargeable batteries in the 2032 (20mm wide, 3.2mm deep) package are generally lithium ion chemistry. This means that, depending on the circuitry they are not always drop in compatible since the voltages and discharge curves differ
- mensetmanusman 6y agoThat’s not true, it depends on the types of materials, how it is disposed, and what the alternatives are. Recall that everything is made out of rearranged earth atoms. So long as you put them back properly, it can be sustainable.
- ostenning 6y agoYeah but is that practically the case? Most people just chuck things in the trash. Most are too busy to even think about disposing of their waste properly.. This is the reality of our society
