Can you charge an Optima battery with a regular charger?

Yes, and you can use any charger on an Optima battery as long as the voltage is regulated properly. If your charger will remain on indefinitely, the voltage should be at 13.8 volts maximum with a one-amp maximum current.

Can a Optima battery be brought back to life?

If you’re using a lead-acid battery, use that setting. Again, make sure you get the polarity right. Black is negative, red is positive. If all goes well, the charger should recognize the voltage of the living battery and start bringing the dead one back to life.

How do you charge a dead OPTIMA Red Top battery?

Do I need a special charger for an AGM battery?

AGM batteries do NOT require a special charger. However, LIKE ANY OTHER BATTERY, it will benefit from the ministrations of a quality “smart” charger. A regular ol’ constant voltage charger, such as you’d buy at the local auto parts store, feeds out power at around 12.7v (some are 12.6v, and some are 12.8v). That’s it.

Will alternator charge OPTIMA battery?

OPTIMA batteries, like any other automotive or marine battery, can definitely be recharged after use. In fact, it happens all the time. Most vehicles have integrated charging systems, most often in the form of an alternator, that recharges OPTIMA batteries while the engine is running.

How do I know if my Optima battery is bad?

Once started, the alternator will start push the voltage up – we aren’t interested in alternator voltage since that tells you about charging, not the condition of your Optima. If the voltage doesn’t hold at 9.5-10.5 volts for 30 seconds, it means your battery is toast.

Do AGM batteries get hot when charging?

It’s normal for AGM batteries to warm up while charging, and you can still use it to charge your other electrical devices. If your AGM battery is hot to the touch, however, then you have a potential problem. It’s overheating while charging (and possibly being overused), so it needs a break.

Can a dead battery be saved?

Usually, dead car batteries may be revived – at least temporarily – to get you back on the road. However, the accumulation of damage may lead to an untimely demise of your car battery, and this typically needs to be replaced. But as the saying goes, prevention is always better than cure.

How many years do OPTIMA batteries last?

In an application like that, they could expect to see an OPTIMA battery last up to four years. However, in a more moderate climate, like San Diego, if someone might see four years out of a flooded battery, they could see up to eight out of an OPTIMA.

Can a battery be fully charged and still be bad?

Batteries with open cells may read fully charged in idle, but they fail under a load test every time. Once a battery reaches this point, there is no going back. The best thing to do is recycle the thing.

How many volts should a Optima battery have?

While measuring battery voltage isn’t the definitive assessment of a battery’s health, it can help alert you to potential issues before they become a real problem. Fully-charged, most 12-volt lead-acid batteries (including AGM products like OPTIMA batteries), should measure at least 12.6 volts.

Are OPTIMA batteries really worth it?

OPTIMA batteries are better than other lead-acid batteries. These batteries are AGM lead-acid batteries where “AGM” stands for “absorbed glass mat.” This means that the mat absorbs the electrolyte inside of the battery, unlike the black box battery, and hence it performs better since it doesn’t allow any leak.

What is special about OPTIMA batteries?

They are dual-purpose, with premium engine cranking power in any temperature and the ability to be deep-cycled, which means they can repeatedly bounce back from deep power drains to full capacity. The lower internal resistance in OPTIMA batteries also provides more consistent power output and faster recharges.

Do AGM batteries hold a charge longer?

CHARGING AN AGM BATTERY

One of the advantages of an AGM battery is they can be charged up to five times faster than a standard flooded battery.

Which Optima battery is better red or yellow?

Deep Cycle Ability. For users with a high demand for power when continuous charging capability (like a trickle charger or alternator) isn’t practical, the Yellowtop Optima is the better choice over the Redtop.

Is OPTIMA Red Top worth it?

The RedTop provides the strongest 5-second burst of power every time you need to start your vehicle, making it perfect for those who value reliability. These batteries are ideal for providing clean ignition power to cars, trucks, and other vehicles that have properly sized alternators.

Is Optima battery AGM or gel?

The acronym “AGM” stands for “Absorbed Glass Mat,” which in the case of a lead-acid battery, means the electrolyte in the battery is absorbed into fiberglass matting in between the cells. All OPTIMA batteries are AGM batteries, but no OPTIMA batteries are gel batteries.

What do the colors mean on OPTIMA batteries?

If you ever get confused about the colored tops, just remember: If it has a dark gray case, then it’s a starting battery; if it has a light gray case, then it’s a deep-cycle (dual-purpose) battery.

How many amp hours does an Optima battery have?

Optima Batteries D27M BlueTop and D27F YellowTop are BCI Group 27 batteries. Their nominal capacity is 66 Ah (20h capacity), with reserve capacity (RC) of 140 minutes.

What type of battery is Optima Blue Top?

AGM battery
The BLUETOP is a high-performance AGM battery with exceptional running time and more recharges than you’d get out of a traditional battery. On top of providing outstanding vibration resistance, the BLUETOP’s efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery.

What is the difference between OPTIMA blue and yellow?

What color OPTIMA is best?

You should choose an Optima YellowTop for any situation that will result in a deep discharge of the battery. This includes things like: Vehicles that don’t even have a charging system: This is common for drag racers and others that don’t want or need the complexity and weight of a charging system.
