The first thing I always like to do with any list involving batteries is to see whether the current options still offer fresh cells, as many sellers like to buy in bulk, and as a result, can often end up supplying you with older packets of cells that might contain duds. After all, no one wants cells that are DOA (Dead On Arrival). With regard to this, the GloFX Lithium Buttons and Energizer 10-Pack seemed to be struggling with quality issues, so they’ve been removed or replaced.
Unfortunately, I also had to remove the Chao Chuang 20-Pack and AmVolt 8-Pack because they were struggling with availability issues. The Chao Chuang is some generic Chinese option that isn’t going to be a huge miss from this list, but it’s a real shame that I couldn’t find any replacement AmVolt CR2025 packets, because the company makes some great button cells, but I’ve recently found many of them struggling with availability issues, not just CR2025 cells - I don’t know if they’re rolling back on manufacturing of button cells to focus on producing larger batteries, or perhaps I’m just overreacting.
For replacements, I’ve looked at a couple of things, namely, my understanding of the cells’ reliability and their cost per unit. Fortunately, I found packages like the LiCB 10-Pack and Celewell 5-Pack, which are both great options from brands that I’m quite familiar with. The Celewell quotes a capacity of 170 mAh, which is higher than the average 150-160 mAh for CR2025 cells, though I couldn’t tell you how accurate their claim is, since I don’t have a discharge curve from the lab – but I’m trusting them on this.
Among many of the generic options that were disappointing to say the least, I did manage to pick up the Skoanbe 5-Pack. The cells have Japanese writing on them, so the manufacturer is probably Japanese, and they are definitely fresh as the advertised batch was supposedly manufactured in October 2019, so they’ll be good till 2023, according to them, which seems about right, as lithium cells have a self-discharge rate of around 10% in 5 years. Just a note with regards to primary cells, a lithium-based battery is denoted by CR to differentiate it from alkaline (LR) and silver-oxide (SR) cells. Also, the first 2 digits of a button cell denote its diameter, and the second 2 denote the thickness multiplied by 10; so, a CR2025 cell has a diameter of 20 mm and a thickness of 2.5 mm.
Also, there’s been some speculation regarding whether the Philips Lithium Minicell pack is a counterfeit from some Chinese company, and I can’t tell you whether this is true, but it’s still a good option with fresh cells that seem quite reliable, and so I’ve left it in.
