Battery Basics

A 36V battery usually has 10 lithium cells connected in series. Each cell is rated at 3.6V, reaching around 42V when fully charged. These deep cycle batteries are ideal for marine use, like powering trolling motors. They offer high energy density, capacity measured in amp hours, and excellent performance and longevity. The benefits of a … Read more

A 3.8 volt reading in a Lithium-ion battery indicates its nominal voltage during use. When fully charged, the battery reaches 4.2 volts and discharges to around 3.2 volts. This average voltage is crucial for energy calculations, where watt hours equal ampere hours multiplied by voltage. Applications for a 3.8 volt cell battery are numerous. They … Read more

A 3-cell 36 Watt-hour (Whr) lithium-ion battery is used in laptops. It measures the battery’s energy capacity. You can calculate battery life by dividing Whr by the laptop’s power consumption in watts. For instance, a 36Whr battery lasts 1 hour at 36 watts. This battery is ideal for certain HP gaming laptops, balancing performance and … Read more

To choose the right battery cells, consider key factors: capacity, voltage, chemistry, discharge rate, cycle life, safety features, and size. Also assess the battery type for your specific application, supplier reputation for quality, and the environmental impact and cost to ensure they fit your budget. Evaluate the size and weight of the battery cells as … Read more

If your phone’s battery is not charging, check the cable and power adapter. Make sure the charging port is clean and free of dust or lint. Try a different outlet or alternative charger. If these steps don’t work, seek professional help or consider replacing the battery for a better solution. If these steps don’t resolve … Read more

Puncturing an alkaline button cell battery can lead to serious consequences. It may cause leakage of harmful chemicals, generate heat, or even result in an explosion. To ensure safety, never puncture, crush, or damage batteries. Proper handling is essential to reduce risk factors and avoid dangerous chemical release. In addition, these batteries contain heavy metals … Read more

A bad battery cell can lead to rapid discharge and quick battery drain, even when the device is off. It may cause overheating during charging or use, increasing safety risks. Furthermore, device performance may decline, resulting in electrical malfunctions and a shorter battery lifespan. The causes of a bad cell often include manufacturing defects, physical … Read more

Connecting positive terminals of battery cells causes a short circuit. This creates an unrestricted electrical connection, allowing current to flow freely. The consequences include overheating, cell damage, or even fire. Such actions are dangerous and must be avoided to ensure safety when handling batteries. Risks associated with this scenario include electrical fires and personal injuries. … Read more

When a battery drops a cell, its voltage and capacity decrease. A lead-acid battery, like a 12V model, produces less power. For a lithium-ion cell, such as the 18650, capacity declines over time while voltage stays stable until major degradation occurs. This loss affects overall battery performance and lifespan. The causes of a dropped cell … Read more

When a battery discharges, its cell potential (Ecell) decreases. This decrease happens because chemical reactions convert stored energy into current. As the battery releases energy, Ecell gets closer to zero. When Ecell reaches zero, the battery is dead and cannot provide power anymore. The voltage of an E cell typically starts high and gradually decreases … Read more
