Higher temperatures can accelerate chemical reactions within the battery, potentially leading to thermal runaway. A study by B. N. Popov (2019) found that 25% of lithium-ion battery failures were linked to overheating caused by overcharging.
Inadequate charging current: Charging a battery with insufficient current can result in incomplete charging. This condition can cause sulfation in lead-acid batteries, which occurs when lead sulfate crystals form on the battery plates, reducing overall capacity. Research by K. V. Rausch (2020) indicates that insufficient charging can decrease battery life by up to 40%.
Incorrect charger type: Using a charger that is not compatible with a particular battery type can damage the battery. For instance, lithium and nickel-based batteries have different charging requirements. If a lithium battery is charged with a nickel-based charger, it may not reach full capacity and could become unstable. The National Renewable Energy Laboratory has noted that using the wrong charger is a common cause of battery failure.
Overcharging: Continuously leaving a battery on charge after it reaches full capacity can cause swelling and leaks due to the buildup of gases. This condition can rupture the battery casing, leading to potential hazards. The USA Department of Energy (2021) warns that overcharging is a critical safety risk that can result in device and battery damage.
Poor charging environment: Charging batteries in extreme temperatures can impair their performance. For example, charging in temperatures above 40°C can accelerate degradation and reduce cycle life. A study published by the Institute of Electrical and Electronics Engineers (IEEE) in 2018 confirmed that operating batteries outside their optimal temperature range shortens lifespan.
In summary, adhering to proper charging practices is essential for maximizing battery performance and safety. Improper charging can lead to reduced lifespan, equipment damage, and potential hazards.
