Battery Buying Guide - The Complete Guide for Choosing the Best Batteries

• Avoid Overcharging: For rechargeable batteries such as Li-ion and Li-Po, avoid charging to 100% too often, as it can accelerate the battery capacity down. Use the built-in charger or one that matches the battery specifications so as not to damage the cells.
• Avoid Battery Deep Discharge: For Li-ion & Li-Po batteries do not let the power drop below 20%, as it can damage the battery cells. It is best to recharge when the remaining power is 30-40%. As for NiMH batteries, it’s best to drain the battery first before recharging to avoid the memory effect that could potentially reduce its capacity.
• Store Batteries in a Cool & Dry Place: Avoid storing batteries in hot places or direct sunlight, as heat can accelerate battery degradation. Also, do not store batteries in too cold conditions (such as in the refrigerator), as extreme temperatures can damage the performance of the battery.
• Use an Appropriate Charger: Use an original charger or one that has the appropriate voltage and current specifications. Avoid using cheap or fake chargers, as they may cause overheating or short circuits.
• Remove Battery When Not in Use for Long Periods: For devices that are rarely used, remove the battery to minimize battery self-discharge. If using rechargeable batteries, store them when they are 40-50% charged, never store them when they are empty as this can accelerate battery damage.
• Avoid Overuse: Avoid overuse such as connected loads that exceed the battery capacity because it can cause the battery to heat up quickly. If the battery feels hot during use, stop using it temporarily and wait for the battery temperature to return to normal. Also, reduce the load connected to the battery to minimize the decrease in battery performance.
• Clean the Battery Terminals Periodically: For primary and rechargeable batteries that are often removed, clean the terminals/ contacts at least twice a month with a dry cloth or alcohol cotton to prevent rusting and reduce power efficiency.
• Avoid Impact or Physical Damage: Don’t drop or squeeze the battery too hard, especially for Li-ion and Li-Po batteries, as it may cause battery leaking and even the risk of battery explosion. If the battery is bulging, stop using it immediately and replace the old battery with a new one.
• Don’t Mix Old and New Batteries: If using primary batteries (such as alkaline), do not mix new batteries with old ones in one device, as it may cause leakage or damage the device. If using rechargeable batteries, make sure they are the same capacity and type if used in devices that require more than one battery.
• Recycle Batteries Properly: Don’t dispose of used batteries carelessly as they contain harmful chemicals that can pollute the environment. Understand where to recycle batteries properly and look for a battery recycling center in your neighborhood. Usually, electronics stores provide a place to dispose of used batteries or you can go to an official recycling center directly to dispose of used batteries safely.

Taking proper care of your battery will extend its life and keep it performing optimally. Avoid overcharging, overheating, and improper use and storage. With good care, batteries can last longer and save costs in the long run.
