Yesterday I purchased a brand new, maintenance-free, 12 volt lead acid car battery. Specs: 47Ah and 450CCA. Lead-acid batteries that are "new" can actually be as much as six months old. They are no longer sold dry without electrolyte, requiring the user to fill the electrolyte. Instead, they are sold with electrolyte, which means they self ...
The liquid-filled lead acid batteries used in automobiles and a range of other products have many great qualities, but are also known to “go bad” with little warning. Fortunately, you can easily do a basic health checkup on any type of lead acid battery by hooking it up to a simple-to-use digital voltmeter.
Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
If the voltage reading is lower than the manufacturer’s specifications, the battery may be weak and need to be replaced. If the voltage reading is within the manufacturer’s specifications, the battery is likely in good condition. To get a more accurate reading of a lead-acid battery’s health, you can use a hydrometer.
A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the battery needs to be recharged. Internal resistance is also an important factor to consider. A battery with high internal resistance will have difficulty delivering power, which can result in poor performance.
Lead-acid batteries are one of the oldest and most widely used types of rechargeable batteries. They are commonly used in vehicles, backup power supplies, and other applications requiring high values of load current. These batteries are made up of lead plates and an electrolyte solution of sulfuric acid and water.
If you’re new to lead acid batteries or just looking for better ways to maintain their performance, keep these four easy things in mind. 1. Undercharging Undercharging occurs when the battery is not allowed to return to a full charge after it has been used. Easy enough, right?

Get PriceA fully charged 12V lead-acid battery should read around 12.6V or higher. A reading below 12.4V indicates partial discharge, while below 12.0V suggests significant discharge or potential failure. For 6V batteries, the corresponding values would be half of those for 12V batteries (6.3V for full charge, 6.0V or lower for discharge).
