OPTIMA Battery Facts

  • OPTIMA batteries are high performance AGM, not gel
  • You can use a high performance alternator with an OPTIMA battery
  • You can charge an OPTIMA battery
  • You can jump start a car with an OPTIMA battery

What is the difference between REDTOI’®, YELLOWTOI’® and BLUETOI’®

batteries?

REDTOP: Use this for normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed. This would describe most stock vehicles.

  • Automotive & RV under-hood starting
  • Heavy equipment where starting is primary function
  • Diesel powered vehicles with no aftermarket electronics

YELLOWTOP: Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles with multiple electronic accessories and vehicles without alternators.
This can also include vehicles with a lot of factory electronics, such as a minivan with power sliding doors and DVD player.

  • Racing vehicles without a charging system (alternator or generator)
  • Dedicated drag racing vehicles
  • Diesel powered vehicles with aftermarket electronics
  • Car audio/video applications exceeding 250 watts over the OE system
  • Vehicles or heavy equipment with inverters, hydraulics, winches or other accessories
  • Electric vehicles

BLUETOP: The BLUETOP Starting battery (dark gray case) is to be used when a dedicated starting battery is required and it should never be used for cycling duty. The BLUETOP Marine Dual Purpose battery (light gray case) can be used for both starting and deep cycling; it is a true deep cycle battery with extremely high cranking power.

  • Use a BLUE TOP Starting battery for marine applications and RVs when the battery’s only function is engine starting
  • Trolling motors, marine applications with heavy electrical accessories, and RVs should use a BLUE TOP Marine Dual Purpose Battery (light gray case)

Note: The difference between BLUETOP and YELLOWTOP deep cycle batteries is that BLUETOP batteries have both automotive (SAE) posts and threaded posts, while YELLOWTOPS (other than D31T) only have SAE posts.

Charging Recommendations

OPTIMA batteries are AGM batteries not gel or regular flooded acid batteries.

Most modern battery chargers, including OPTIMA chargers, have a built-in AGM charge setting, which should be used for your OPTIMA battery. If purchasing a new battery charger, make sure it has AGM compatibility or a separate AGM setting. Do not use gel or gel/ AGM settings, as this will not fully charge an OPTIMA battery and can damage it over time.

Repeatedly charging at high current levels can damage your OPTIMA battery. For best results, use the following recommendations:

Charger Type Amps Target Volts
Regular/Automatic 10 13.8to15.0
Flot 1 13.2 to 13.8

Haw Lang ta Charge

If you have an automatic charger, let it run until the charger indicates the process is complete. If you have a manual charger, estimate charging time for a completely discharged battery (11.2v) by multiplying the capacity (amp hours or Ah) by 1.2 for a rough estimate of charging hours. If your battery is not completely discharged the time will be less.

Charger Setting

Capacity {Ah)| 2 amps| 5 amps| 10 amps
38| 23 hours| 9 hours| 4.5 hours
44-55| 33 hours| 13 hours| 6.5 hours
66-75| 45 hours| 18 hours| 9 hours

Deeply Discharged Battery

If an OPTIMA battery is deeply discharged (below 10.5 volts) most basic chargers will not supply a charge. OPTIMA chargers are designed specifically to recover batteries discharged as low as 1.25v. to charge the battery, you can wire a 2nd fully charged automotive battery (12V +) to the discharged AGM in parallel ( + to + and – to -). Then hook up the charger to the discharged battery, setting the charger at 10 amps. Leave for 2 hours, monitoring periodically. When the discharged battery reaches 10.5 volts or above, remove the 2nd battery and continue charging the AGM until fully charged. In most cases the AGM battery will be recovered.

It’s okay for the AGM battery to get slightly warm during the charging process. Hot to the touch means there’s a short and the process should be discontinued. Have your alternator checked immediately.

What are storage recommendation far OPTIMA Batteries?

The most important consideration when storing any battery is to make sure the voltage never drops below 12.4 volts. We recommend using a type of “battery maintainer” – a device that will monitor you battery and keep it at full potential during storage.

There are 2 types at maintenance chargers:

  1. Traditional “Float” chargers, which provide constant voltage with tapering amperage to the battery even when it is fully charged. For float charging we recommend 1 amp max, 13.2-13.8v.
  2. Fully automatic “multi stage or multi step” chargers, which monitor the battery and charge it as necessary. Some of these multi step chargers, such as OPTIMA chargers, are also capable of working well as a battery charger.

If it is not possible to use a maintenance charger, disconnect the battery from the vehicle during storage to prevent the vehicle from discharging the battery. Always provide a full charge with a battery charger prior to storage and then check the battery voltage every 3-6 months and charge if it falls below 12.4v.
Also, when possible, store your batter in a cool, dry location.

Fitments

Direct fit battery recommendations can be found at www.optimabatteries.com/battery_selector/. If an exact fit size is not listed, measure the dimensions of your existing stock battery to see if there’s an OPTIMA battery that will fit the battery compartment. Detailed dimensions and specifications can be found at www.optimabatteries.com/optima_products/.

If using a OPTIMA battery in a custom application, consider the fallowing:

  • Hood Clearance – at least 3/4″ clearance between terminals tops and underside of hood
  • Trunk/Interior Mounting – If battery is mounted inside passenger compartment or trunk, it must be vented to outside of vehicle.
  • Side Terminals – If using a dual terminal battery in a vehicle that uses the top terminals, ensure that side terminals cannot come into contact with metal. Keep post protectors on terminals not in use.
  • Battery Modifications – Cutting, drilling, trimming or otherwise modifying the battery may present a safety hazard and voids the warranty
  • Mounting – Battery must be securely mounted. Terminals are not intended to be used to secure battery.
  • Heat – Protect the battery from any high heat source such as a turocharger.

Troubleshooting battery/electrical issues – Why is my battery dead?

Fully charged starting batteries should measure- 12.8v. Deep cycle batteries should measure – 13.1 v. When the engine is running this measurement should be 13. 7 -14. 7v. If you don’t have a multimeter you can test this by starting the car and turning on the headlights. If they are dim, it indicates the lights are running off the battery and that little or no juice is being produced by the alternator. If the lights get brighter as you rev the engine, it means the alternator is producing some current, but may not be producing enough at idle to keep the battery properly charged. If the lights have normal brightness and don’t change intensity as the engine is revved, your charging system is probably functioning normally.

If this checks out okay, you should check whether or not the battery is holding a charge, or if something on the vehicle is discharging the battery.

There are 3 likely scenarios to explain the problems you’re having:

  1. A high parasitic draw (“key off” load). This can quickly discharge a battery and decrease its service life. This may be caused by a trunk light, cigarette lighter, dock/radio, alarm system or any other electrical device. Current drain on the battery can be checked with an ammeter. With the ignition off, disconnect one of the battery cables. The normal  current drain on most vehicles should be about 25 milliamps or less. If the key-off drain exceeds 100 milliamps, there’s an electrical problem that requires further diagnosis. If you don’t want to take your car to a mechanic, the easiest way to isolate the problem is to pull one fuse at a time from the fuse panel until the ammeter reading drops.
  2. A problem with your battery is causing it to not hold a charge. To check this, wait 12-24 hours after charging to the full voltage, keep battery out of the vehicle and measure its voltage (another faster but less preferable way to do this is to turn on the high beam headlights for 15 seconds, turn them off, wait 5-10 minutes, then check the voltage). If you measure the voltage of the battery the next day, week, or even a month later, the voltage be close to the max voltages listed above. If the voltage holds when not installed in your vehicle, but drops when it is in your vehicle, see #1 above.
  3. The battery was somehow discharged, and your maintenance charger is not able to properly charge your deeply discharged battery. Please see the directions for charging a deeply discharged battery.

Connection Multiple Batteries in parallel

If your battery application requires more starting power or reserve capacity than one OPTIMA battery can provide, you can install multiple batteries in parallel ( + to + and – to -). Each time you add a battery in parallel you increase the CCA and reserve capacity while voltage remains the same.

Suggestions far connecting batteries in parallel:

  • Use batteries of identical make, model, and age
  • Make sure cable gauge is sufficient enough to handle the higher current flow
  • Prevent cables from shorting
  • Use only high quality connectors and clean all contacts prior to installation
  • Periodically check all connections to ensure a firm connection
  • Contact your automotive service center if you are unsure of how to handle these procedures.
  • Connect + cable to first battery and – cable to last battery to more evenly distribute current flow.
