Electromagnetic interference, or radio-frequency disruption if you prefer, is due to nearby sources. These may be a welder, a large electric motor, or any device using electromagnetic induction or electrostatic coupling.
Before we delve into the details of how to charge a lead-acid battery safely, we start with two precautions. In the first instance, we assume your charger and battery are in tip-top condition.
Float voltage is the voltage that is required to maintain a battery fully charged. Maintaining battery charge level at 100% is also called Trickle Charging. The idea is to keep the battery charging till it is needed. Recommended Float Voltage Value The appropriate float voltage depends on battery type as well as room temperature at […]
Trickle charging is used by battery chargers to maintain the battery in fully charged state. The keyword here is maintain. Let’s understand how. Battery Self-discharge A battery is said to be fully charged when it reaches 70-80% charge. However, even if there is no load attached to the battery, chemical reactions continue, though at a […]
Photo Courtesy: superlib.eu Temperature is a very important factor in battery as well as battery charger performance. First you need to understand how temperature affects battery operation. Only then will you be able to appreciate the need to control it. Effects of Temperature on Battery The ideal battery operation temperature is between 18 to 25 ◦C. […]
A battery gives you power to operate gadgets and a battery charger gives the battery power to continue working. So it’s important to know how a battery charger works. Photo Courtesy: solarstik.com Workings of a Battery Charger As you know from a previous post, a battery converts chemical energy stored in it to electrical power. […]
A standard battery charger, whether it is slow or fast, keeps supplying current to the battery while it is plugged in. This can be harmful for your batteries because overcharging can damage them. This can at times affect your gadgets too, because many batteries charge while they are inside the gadget (a laptop, for example). […]
