For example, active guitar pickups, preamps, and effects pedals in an acoustic guitar or a Sustainiac can last only 4-8 hours of continuous use.

A baby swing is another high-drain device that requires a lot of energy. This means you'll likely burn through disposable batteries very quickly, sometimes in a matter of days.

Microcontrollers like those in an Arduino project can also be high-drain devices. An alkaline 9V battery might power a simple Arduino project for less than 24 hours.

These devices require a lot of power, so it's best to use a battery specifically designed for high-drain devices.

Alkaline batteries can last for years if stored properly. Storing them at stable, moderate temperatures (15°C–25°C) with low humidity ensures maximum retention of charge.

Elevated temperatures can significantly reduce a battery's shelf life, with a rule of thumb suggesting that for every 10°C increase in temperature, the battery's shelf life roughly halves. This means that storing batteries in a hot garage or attic can greatly reduce their lifespan.

Moisture can also cause corrosion at the terminals and compromise the battery's sealing, leading to leakage and self-discharge. This is why it's essential to store batteries in a dry place, away from direct sunlight and moisture.

Alkaline batteries undergo a natural, slow chemical reaction even when not in use, causing gradual loss of stored energy. The self-discharge rate for modern alkaline batteries is approximately 2-3% per year at room temperature.

Here's a rough estimate of the self-discharge rate for different storage conditions:

Keep in mind that storage conditions can exacerbate capacity loss significantly, so it's crucial to store batteries properly to maintain their charge.

Alkaline batteries are a popular choice for many devices, but how long do they actually last? Top-quality alkaline AA batteries can provide power for 200 to 1,000 hours. They self-discharge at around 3% to 5% per month under proper storage conditions.

To give you a better idea, here's a breakdown of their shelf life: alkaline AA batteries can last up to 5 to 7 years when stored properly, unused. This makes them a great option for devices that don't require high-drain power.
