1.5V lithium battery: Constant voltage output, stable around 1.5V from full to empty, device performance does not degrade. Alkaline battery: New battery 1.6V, voltage continuously drops after use, device performance gradually weakens. NiMH battery: Nominal 1.2V, new battery about 1.4V, voltage drops after use.
1.5V lithium battery: Rechargeable 1000+ times, calculated at once weekly charging, can be used nearly 20 years. Alkaline battery: Single-use, not rechargeable. NiMH battery: Rechargeable 500-800 times, service life about 50%-80% of lithium battery.
1.5V lithium battery: Monthly self-discharge rate <3%, still maintains sufficient charge after long-term storage. Alkaline battery: Annual self-discharge about 2-3%, good storage performance. NiMH battery: Monthly self-discharge 15-20%, charge significantly degrades after long-term storage.
1.5V lithium battery: Sealed structure, no leakage risk. Alkaline battery: May leak in later use or long-term storage, corroding devices. NiMH battery: Leakage risk lower than alkaline, but still possible.
