A lead-acid battery is a type of battery that uses lead as the negative electrode material and lead dioxide as the positive electrode material. It is a very common type of battery. Due to its high safety, non-toxicity, and long cycle life, lead-acid batteries play an important role in automotive start-stop systems, motorcycles, lawn mowers, and toys. Additionally, lead-acid batteries do not contain nickel or cobalt, making them more environmentally and human-friendly. Also, it's a maintenance-free battery without adding water or acid.

When it is used correctly under the manual instructions, our products can serve most normal devices. Please check your product and purchase the correct specs.

If you need to change to an existing order, you can directly contact our customerservice email and leave your contact information. We will reply to you as soonas we see your message within working days.

Batteries are typically rated using CCA (Cold Cranking Amps), which measures how much current a fully charged battery can deliver for 30 seconds at a temperature of -18°C. Generally, the electrical system in your vehicle is designed to draw a fixed amount of current for each task it performs, so batteries with a higher CCA won't start your vehicle faster or improve its performance.The CCA rating of a battery will gradually decrease over time, so batteries with higher CCA ratings may last longer.However, other factors such as the quality of construction, the strength andthickness of the internal lead plates, and the amount of electrolyte also playa significant role in determining the battery's lifespan.

Uplus batteries are available through authorized distributors, auto parts stores, and online retailers. Visit uplusbatteries.com.

Most car batteries last 3–5 years, depending on driving habits, climate, and battery type. AGM batteries often last longer with proper care. Uplus AGM car batteries can be last to more than 5 years.

Premium Uplus AGM start-stop batteries range from $139–$199.

Connect red to the positive (+) terminals on both batteries, then connect black to the negative (–) terminal on the donor and a metal ground on the dead car. Start the donor car, then the dead one. Remove cables in reverse order.

A healthy car battery reads about 12.6 V when fully charged and 13.7–14.7 V when the engine is running.

Turn off the engine, then remove the negative (–) cable first, followed by the positive (+) cable.

After disconnecting both two terminals, loosen the hold-down bracket and carefully lift the battery out.

Replace it every 3–5 years or sooner if you notice slow starts, dim lights, or frequent jump-starts. If your car battery is Uplus car battery, you can replace car battery over 5 years.

Use a compatible charger, connecting positive to positive and negative to negative. Charging time ranges from 4–12 hours depending on battery size and charger output.

Typically 4–12 hours for a moderate charge; longer if the battery is deeply discharged.

Place the new battery securely in the tray, connect positive (+) first and negative (–) last, and tighten connections firmly.

Use a multimeter: a fully charged battery should read 12.6 V or higher with the engine off.

You can check a car battery in a few simple ways: 1. Use a multimeter: 1) Set it to DC voltage. 2) Place the red probe on the positive (+) terminal and the black probe on the negative (–) terminal. 3) A healthy, fully charged battery should read around 12.6 volts with the engine off. 4) Readings below 12.2 V indicate a weak or discharged battery. 2. Check with the engine running: 1) Voltage should rise to 13.7–14.7 V, showing the alternator is charging properly. 3. Visual inspection: 1) Look for corrosion on terminals, loose cables, bulging sides, or leaks. 2) Clean corrosion with baking soda and water if needed.

Common signs include slow cranking, dim headlights, clicking noises, or a voltage reading below 12V.

Possible causes include parasitic drain, corroded terminals, a weak alternator, or an old battery nearing the end of its life.

A standard 12-volt car battery can deliver 300–800 amps momentarily to start the engine and typically has a capacity of 45–75 amp-hours (Ah). The exact rating depends on the vehicle type and battery design.

Disconnect cables, then scrub terminals with a mix of baking soda and water. Rinse and dry before reconnecting.

Connect the positive (+) terminal first, then the negative (–) terminal.
