How to Tell If a Battery Is Good

The easiest way to tell if a battery is good is to test its voltage using a multimeter or battery tester. If the reading is at or near the rated voltage (e.g., 1.5V for AA, 12.6V for a car battery), then the battery is still good. If it falls significantly below that range, it’s time … Read more

How to Increase Amperage Without Increasing Voltage

You can increase amperage without increasing voltage by reducing resistance or connecting power sources in parallel. This technique is fundamental in electronics, especially when you need more current flow for devices without risking voltage-sensitive components. For example, high-powered LED arrays or motors often require more current, but too much voltage can cause damage. That’s why … Read more

How to Fix Low Voltage Car Battery

To fix a low voltage car battery, you need to recharge it using a proper battery charger, check for parasitic drains, clean any corrosion, and test the battery’s health. A car battery showing low voltage doesn’t always mean it’s dead—but it does signal that immediate attention is needed to avoid being stranded. Did you know … Read more

AGM Battery Voltage Chart

An AGM battery is fully charged at 12.8 to 13.0 volts, 50% charged at around 12.2 volts, and considered discharged below 12.0 volts. This voltage-based measurement is one of the simplest and most accurate ways to check the health and state of charge (SOC) of your AGM (Absorbent Glass Mat) battery—without guesswork. Whether you’re maintaining … Read more

Car Battery Voltage

The normal voltage of a fully charged car battery is between 12.6 and 12.8 volts when the engine is off. Anything below 12.4 volts typically indicates a partial charge, while readings under 12.0 volts suggest a deeply discharged or potentially failing battery. Imagine getting into your car, turning the key, and hearing only a click—or … Read more
