AGM technology was developed in 1985 for military aircraft to reduce weight, increase power handling and improve reliability. The acid is absorbed by a very fine fiberglass mat, making the battery spill-proof. This enables shipment without hazardous material restrictions. The plates can be made flat to resemble a standard flooded lead acid pack in a rectangular case; they can also be wound into a cylindrical cell.
If the battery were a perfect power source and behaved linearly, the discharge time could be calculated according to the in-and-out current. “What has been put in can be taken out in the same form over time” is the argument, and in our example a one-hour charge at 5A should enable a one-hour discharge at 5A, or a 5-hour discharge at 1A. However,
Like humans, batteries function best at room temperature, and any deviation towards hot and cold changes the performance and/or longevity. Operating a battery at elevated temperatures momentarily improves performance by lowering the internal resistance and speeding up the chemical metabolism, but such a condition shortens service life if allowed to continue for a long period of time.
The purpose of a battery is to store and release energy at the desired time and in a controlled manner. This section examines discharges under different C-rates and evaluates the depth to which a battery can safely be depleted. Chapter 5 also observes different discharge signatures and explores how certain patterns can affect battery life. But first, let’s look at charge and discharge rates, also known as C-rate.
Crash Course on Batteries
Here are excellent articles collected from net that explain basic terms used with batteries. Very useful text to read even if you have certain knowledge about batteries.
There are many different battery ties and each is specific on how to test if it is empty, how to use, charge. There are many advices that will ensure that you do not destroy battery and device it is powering. It will help you decide what battery is best for your project. Very useful text to read.
Packaging and Safety
Batteries come in many different packaging. Sometimes they consist of more batteries combined together. Batteries are useful but can be dangerous in not used properly. Articles from this section of www.electronics-base.com will help you answer all questions you have from this area.
Charging various types of batteries can be tricky. Here are explained ways and conditions of charging different types of batteries. All criteria of knowing how much is battery full and everything you need to know when designing battery power supply with charging option for your device
