Frequently Asked Questions
What is the warranty on my battery?
What is the warranty on my battery?
To obtain a replacement battery, you must present your original battery to an IB Authorized Warranty Dealer or All Battery Center Store that has an appropriate replacement battery in stock. That dealer will have a reasonable time to test your original battery and, if defective, replace it according to the terms of the limited warranty. Please note, the battery must be fully-charged at the time of testing.
Where can I take my battery if it's bad?
Where can I take my battery if it's bad?
We have nationwide warranty on our vehicle batteries. You do not need to take the battery back to the original location where you purchased it. Visit our online to find the nearest dealer near you.
Can I overcharge a battery?
Can I overcharge a battery?
Yes. A battery that swells and becomes hot to the touch is also a direct result of overcharging and can be very dangerous and even explode. Always use the correct charger when charging a car battery, and have it checked periodically by a specialist if charging must be done frequently. Pay attention to labels that indicate exactly how the battery should be charged; this helps eliminate overcharging and possible harm and injury.
How should I store my battery, when not in use?
How should I store my battery, when not in use?
Clean the battery case with baking soda and water and scrub the terminals with a wire brush. Check the water level and add water if needed. Test your battery with a hydrometer and/or a voltmeter to ensure the battery is fully charged. If needed, charge your battery. Check the water level and state of charge every 45-60 days. If needed, add distilled water and charge.
NOTES: Batteries stored in a discharged state are susceptible to freezing in cold weather and sulfation. A fully charged battery will not freeze unless the temperature reaches approximately 75° F (24° C) below zero. But if discharged, it can freeze at 15° F (-9° C).
What does Li-ion and Ni-MH mean?
What does Li-ion and Ni-MH mean?
They represent different types of rechargeable batteries. Li-ion stands for Lithium Ion, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging. Ni-MH stands for nickel-metal hydride where the negative electrode is made from a hydrogen-absorbing alloy.
