Batteries have been with us for over two centuries, although they only became consumer devices in the 1950’s. In those innocent days back then, folk believed labels that promised ‘long life’. Nowadays of course, batteries play a more critical role. The good ones we can trust are also becoming more expensive. Hence the need to understand the five key battery parameters behind their performance.
5 Key Parameters Determining Battery Performance
Consumer preferences are shifting from single-use, to rechargeable batteries for convenience. Although wise ones may still keep a supply of single-use batteries for emergency use. We wish we could say that the raw materials from both battery types are recycled, but society has a way to go with that.
There are five key battery parameters we should understand as consumers, although battery labels may be to small to list them all. Those factors are set to play an increasing role in purchasing decisions, although we do need to offset them against the price we pay.
- The total amount of energy a battery can theoretically store when it holds a full charge. This value gradually reduces as the battery ages.
- The rate at which a battery is able to deliver this potential over time. This value also gradually reduces as the chemicals in the battery get older.
- The useful lifespan of a battery, during which the above two factors are still acceptable. However after that, the battery is still not ‘dead’.
- Cost, as we have already mentioned, is also very important, because the purchasing price affects our pocket and our cash flow.
- Some batteries are safer that others, with the more powerful ones tending to be more risky. We need to know the signs of a failing battery.
Even ‘dead’ batteries still hold a charge, because the chemicals inside them are still active. We should take care to dispose of spent batteries responsibly, so someone, somewhere may recover their valuable materials safely.
