Batteries in Industries

Learn about unique applications and what features to look for when choosing a battery. Consumers are the first to hear about an apparent battery breakthrough. To get top media attention, the new super battery promises to also satisfy the need for electric vehicle (EV). Personal mobility is an emotional issue that cannot be suppressed, even […]

Hybrid Electric Vehicles and the Battery

Hybrid Electric Vehicle (HEV) Governments are asking the public to reduce fuel consumption and lower pollution. They do this without imposing a change in driving habits and the HEV fits the bill. Japan is leading in adapting the HEV because of high fuel costs and environmental concerns. The purpose of the HEV is to conserve […]

How Low can a Battery be Discharged?

Discover what causes short runtimes Not all battery energy can or should be used on discharge; some reserve is almost always left behind on purpose after the equipment cuts off. There are several reasons for this. Most mobile phones, laptops and other portable devices turn off when the lithium-ion battery reaches 3.00V/cell on discharge. At […]

How does Rising Internal Resistance affect Performance?

Understanding the importance of low conductivity Capacity alone is of limited use if the pack cannot deliver the stored energy effectively; a battery also needs low internal resistance. Measured in milliohms (mΩ), resistance is the gatekeeper of the battery; the lower the resistance, the less restriction the pack encounters. This is especially important in heavy […]

How to Define Battery Life

Become familiar with battery fade and how the ready light can deceive the user. Folks have been using rechargeable batteries for over 100 years but this marvelous power source is still poorly understood. The battery is a silent worker that delivers energy until it quits of exhaustion and old age. It is more prone to […]

How to Prime Batteries

Discover what a battery needs to get going and maintain a long life. In many ways, a battery behaves like a human being. It senses the kindness given and delivers on the care given. It is as if the battery has feelings and returns on the benevolence bestowed. But there are exceptions, as any parent […]

How to Verify Sufficient Battery Capacity

Know how to maintain a battery fleet and eliminate the risk of unexpected downtime. A battery performs well when new but the capacity soon begins to fade with use and time. To assure reliable service during the life span of the battery, design engineers oversize the pack to include some spare capacity. This is similar […]

Discharging at High and Low Temperatures

Explore the limitations when operating a battery at adverse temperatures and learn how to minimize the effects. Like humans, batteries function best at room temperature. Warming a dying battery in a mobile phone or flashlight in our jeans might provide additional runtime due to improved electrochemical reaction. This is likely also the reason why manufacturers […]

Discharge Characteristics of Li-ion

Learn about the difference of energy and power requirements in a battery. The early Li-ion battery was considered fragile and unsuitable for high loads. This has changed, and today lithium-based systems stand shoulder to shoulder with the robust nickel and lead chemistries. Two basic types of Li-ion have emerged: The Energy Cell and the Power […]

Basics about Discharging

Learn how certain discharge loads will shorten battery life. The purpose of a battery is to store energy and release it at a desired time. This section examines discharging under different C-rates and evaluates the depth of discharge to which a battery can safely go. The document also observes different discharge signatures and explores battery life under […]
