🧪 Alkaline vs Silver Oxide Replacements
| Feature | Alkaline (LR44, AG13) | Silver Oxide (SR44, 357) |
|---|---|---|
| Voltage | 1.5V | 1.55V |
| Capacity | Lower (~120mAh) | Higher (~150–200mAh) |
| Price | Cheaper | Slightly more expensive |
| Voltage Stability | Declines over time | Stable until depletion |
| Ideal for | Toys, remotes, clocks | Medical, measurement devices |
Silver Oxide batteries (like SR44 or 357) last longer and deliver more consistent voltage — perfect for digital instruments or high-drain electronics.
