Wondering how to charge a deep cycle battery the right way? You’ve come to the right place! So you took the plunge and invested in a deep cycle battery. You’re excited about spending endless hours on the water and powering your trusted trolling motor and favorite fishing gadgets. But in order for your battery to […]
Are you wanting to use solar power off grid? If so, you’re going to need off grid solar batteries–and they’d better be reliable. If you use a grid-tied or hybrid system, it’s possible to run your solar without batteries. But as soon as you go off the grid, batteries become an essential part of your […]
Know how to apply an equalize charge and not damage the battery. Stationary batteries are almost exclusively lead acid and some maintenance is required, one of which is equalizing charge. Applying a periodic equalizing charge brings all cells to similar levels by increasing the voltage to 2.50V/cell, or 10 percent higher than the recommended charge […]
Learn what you can do to prevent a Li-ion battery to fall asleep. Li-ion batteries contain a protection circuit that shields the battery against abuse. This important safeguard also turns the battery off and makes it unusable if over-discharged. Slipping into sleep mode can happen when storing a Li-ion pack in a discharged state for any […]
Compare battery energy with fossil fuel and other resources Lifting off in a large airplane is exhilarating. At a full weight of almost 400 tons, the Boeing 747 requires 90 megawatts of power to get airborne. Take-off is the most demanding part of a flight and when reaching cruising altitude the power consumption decreases to […]
Learn about the revival of the fuel cell for transportation The fuel cell as a propulsion system is in many ways superior to a battery because it needs to carry less energy storage by weight and volume compared to a vehicle propelled by batteries only. Figure 1 illustrates the practical driving range of a […]
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 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 […]
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 […]
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 […]
