Let's assume two mobile phone batteries that have the same physical size, (edit: same price too), but different properties:

Battery 1

• 4000 mAh
• 25 Watts maximum charging speed under constant conditions.
• Usable up to 500 charging cycles.

Battery 2

• 3000 mAh
• 16 Watts maximum charging speed under same conditions.
• Useable up to 50000 charging cycles.
• Weighs 150% as much as Battery 1.

Edit: Useable means: Before the battery performance starts to plunge and to cause unexpected poweroffs of the device.
