## How that compares

*Car battery against things of a similar time.*

- Laptop: 3–8 yr
- Coffee machine: 3–8 yr
- Printer: 3–10 yr
- Tablet: 3–8 yr
- Car battery: 3–7 yr
- Red fox: 2–15 yr
- Giant Pacific octopus: 3–5 yr
- Wild turkey: 3–13 yr

## What that means over time

*Assuming the typical lifespan above and immediate replacement.*

| Period | How many you would buy |
| --- | --- |
| Per year | 0.25 replacements |
| Over 10 years | 2.5 of them |
| Over a 30-year mortgage | 7.5 of them |

> Lifespans are medians under ordinary use, not guarantees. Maintenance, how hard it is used, and build quality move individual examples a long way in both directions — which is why the range above is as wide as it is.
