There are telltale signs that your car's lead acid battery might need water replenishment. Maintenance-free or valve-regulated lead-acid batteries (VRLA) are the types that don't need watering ...

Texas A&M University scientists have been working with metal-free, water-based battery electrodes, and they’re finding that the difference in energy storage capacity is as much as 1,000%.

The team uses water to replace organic electrolytes – which enable the flow of electric current between the positive and negative terminals – meaning their batteries can’t start a fire or blow up – ...

Water batteries have a lot of competitors, when it comes to storing energy. Some companies, including the car company GM, ... and they don't need to disturb free-flowing streams and rivers.

Researchers at Texas A&M University have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes. These batteries are different from lithium-ion batteries ...

If you're using EGO batteries and EGO tools for your home and lawn, here's a quick look at how safe they are to be used with water and whether the EGO warranty covers water damage, just in case ...

Three years ago, Ted Treadwell turned his water heater into a battery. His home in Santa Rosa, California, had relied on a gas-powered furnace and water heater for a quarter-century to stay warm. But ...

Car batteries typically last three to five years, according to AAA, spanning from 58 months or longer in the farthest northern regions of the U.S. to less than 41 months in the most southern regions.

The battery uses a two-chamber design separated by an anion-selective membrane. In one chamber, contaminated water flows past an electrode containing copper hexacyanoferrate (CuHCF), a porous material ...
