A generator does not normally damage a battery when it powers the correct charger. Damage happens when voltage, charging profile, polarity or battery chemistry is wrong, or when an unregulated DC outlet is … Read more
Most EV batteries are designed to remain useful for the life of the vehicle, not to fail when the warranty ends. U.S. Department of Energy guidance cites modeled lifetimes of about 12 to … Read more
The best inverter battery is not the one with the biggest amp-hour label. It is the battery bank that can supply the inverter’s continuous and surge current, deliver the required runtime and stay … Read more
No, a standard 12V charger cannot correctly charge an 18V battery. Its output is too low to bring the higher-voltage pack to full charge, and improvised connections can bypass the protections built into … Read more
Battery terminal covers are a small part with a serious job: preventing an exposed terminal from contacting metal and creating a high-current short circuit. If a terminal can be reached by a tool, … Read more
A battery cable that is warm under a heavy load may be normal, but one that is painfully hot, smoking, discolored or melting is a fault. Stop using the equipment and disconnect it … Read more
Do not put NiCd batteries in a NiMH charger unless the charger explicitly supports both chemistries. NiMH and NiCd cells may share the same 1.2-volt rating and physical size, but safe charging depends … Read more
A generator may keep its starting battery charged, but many portable models will not do it automatically just because the engine is running. The answer depends on the generator’s charging circuit, not its … Read more
