Modern batteries have capacities reaching over 3,000 mAh, though it depends on their size. Find options with plenty of energy storage to ensure you get the most from your money.
4. Shelf Life
Another eco-friendly consideration is the battery’s shelf life. How long will it last in storage before you need it?
Batteries gradually lose their power even when not used in an electronic device. Examine this calendar degradation because all batteries lose some charge when kept in drawers.
The shelf life depends on the product you pick, considering the quality difference between brands. That said, you can count on rechargeable batteries to have a five-year shelf life.
While a product’s shelf life is critical, you can control some aspects. For example, storing the batteries at room temperature prevents weather from accelerating the degradation.
5. Recyclability
A battery could exceed 3,000 mAh and have a 10-year shelf life. However, it will eventually run out of power and require disposal.
Therefore, you need recyclable batteries to reduce waste and help the environment. These tiny products contain valuable metals like nickel and copper that can be extracted and repurposed.
Recyclable batteries also matter for the sake of the soil outdoors. Batteries can leak acid and damage valuable water sources and the air when in landfills.
Battery recycling is also essential because it includes greenhouse gas (GHG) emissions. If more people recycle these power units, fewer will be necessary for future production.
6. Environmental Credibility
How can you find features that stand out in your eco-friendly battery comparison? One critical strategy is looking at their environmental credibility.
Evaluate brands and their battery products for environmental certification from reputable third parties. For instance, consider the International Organization for Standardization (ISO) and its criteria.
If a company has ISO 14001 certification, its batteries are more environmentally reliable. This accomplishment signals that the business has minimized its ecological footprint and complied with environmental regulations.
Another noteworthy standard is PAS 2060, a metric determining carbon neutrality. PAS 2060 battery producers work toward net-zero emissions through carbon reduction and offsets.
