Odyssey ODX-AGM65 vs. Odyssey 65-PC1750T

Odyssey ODX-AGM65 and Odyssey 65-PC1750T batteries are the same batteries - the Odyssey 65-PC1750T battery is simply rebranded into the Odyssey ODX-AGM65 battery.

The label 'Odyssey 65-PC1750T' means:

• manufacturer: Odyssey
• battery group size: 65
• PHCA: 1750 Amps

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) nominal capacity is 74 Amp-hours (20h, down to 10.5 volts), and it features 950 CCA Amps and 145 minutes Reserve Capacity.

Also, Odyssey ODX-AGM65 (Odyssey 65-PC1750T) features a 5000 Amps short circuit current - its plates are made using 99.99% pure lead, ensuring thin plates, low internal resistance, and low self-discharge rate.

Its intended service life is 3-10 years, depending on the application and operating temperature.

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) tolerates up to 400 cycles down to 80% of DoD (Depth of Discharge) and can be fully recharged in 4-6 hours using smart AGM chargers.

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) Performance Data

The following chart shows performance data of the Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM battery when being discharged down to 10.05 volts at 77°F (25°C).

Note: we emphasize this 10.05 volts (1.675 volts per cell) since most of the batteries are tested down to 10.50 volts (1.75 volts per cell). This just shows the recoverability of the Odyssey AGM batteries when being discharged almost fully.

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) features an operating temperature range from -40°F (-40°C) to 113°F (45°C). So, it can be freely left in the vehicle during the winter.

Storage time generally depends on the battery temperature, and it is recommended that the battery be charged when its voltage drops down to 12.0 volts (35% SoC - State of Charge). Depending on the temperature, storage time is:

• 41°F (5°C): 48 months,
• 59°F (15°C): 36 months,
• 77°C (25°C): 24 months,
• 95°F (35°C): 12 months,
• 113°F (45°C): 6 months.

To achieve a long operating life, the Odyssey ODX-AGM65 (Odyssey 65-PC1750T) battery should be kept nearly fully charged, at approximately 12.8 volts.

Its state of charge can be determined using a common voltmeter. Depending on the measured voltage (at 77°F, 25°C), the State of Charge (SoC) is:

• 12.84+ V: 100% SoC,
• 12.65 V: 85% SoC,
• 12.50 V: 75% SoC,
• 12.18 V: 50% SoC,
• 12.00 V: 35% SoC,
• 11.88 V: 25% SoC.

Depending on the use, Odyssey ODX-AGM65 (Odyssey 65-PC1750T) end charging voltage should be kept between:

• cyclic charge: 14.4 - 14.8 volts,
• float charge: 13.5 - 13.8 volts.

Note: Charging voltage should never exceed 15.0 volts because such charging voltage may cause pressure valves to open and release excess hydrogen, oxygen, and even electrolytes outside, shortening the operating life of the battery.

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM Battery as Starting Battery

With 950 CCA Amps and 1750 PHCA Amps, Odyssey ODX-AGM65 (Odyssey 65-PC1750T) is an excellent starting battery, being able to crank very large engines at very low temperatures.

If you are looking for a robust and strong automotive battery for your vehicle that can fit the battery compartment, consider this battery.

For vehicles that feature a large number of electronic and electrical devices (audio systems, alarms, GPS, USB, and other small devices' chargers, etc.) that should operate while the main engine is off, Odyssey ODX-AGM65 (Odyssey 65-PC1750T) battery can supply low currents for longer periods of time and still be able to crank the engine.

Note: if you plan on wintering your battery by leaving it fully charged in the vehicle, be sure that there are no parasite currents at all. If unsure, when wintering the battery, disconnect the negative cable (or both cables!).

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM Battery as Trolling Motor Battery

Generally, the Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM battery is not intended for marine applications.

But if you have a small boat and an electric trolling motor that draws, for example, 25 Amps max, and the cables can fit automotive SAE posts, then you can expect at least 145 minutes (2 hours, 25 minutes) of operation at full throttle from the new, fully charged battery.

Since trolling motors seldom run at full throttle all the time, one can expect even longer trolling time in such conditions.

After that, the battery must be properly charged in 4-6 hours, or preferably a little bit longer.

How to Charge Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM Battery

Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM battery is designed to accept charge quickly, allowing the battery to be recharged rather fast - in 4 to 6 hours, which is really fast for AGM batteries; that would mean that the recommended charging current is in the ~12 to 18 Amps range.

Personally, the Odyssey ODX-AGM65 (Odyssey 65-PC1750T) AGM battery should be recharged using 10 Amps (or less) charging currents from advanced/smart AGM battery chargers that support several charging modes, including desulfation, cell equalization, maintenance mode, etc. Also, temperature compensation is a must-have feature.

One of the excellent and very popular such battery chargers is the NOCO GENIUS10 10A Smart Car Battery Charger, which can be used to charge 6V and 12V lead acid batteries, 12V lithium batteries, can be used to repair 12V lead-acid batteries, can act as 12V power supply, features temperature sensor, can recover (or at least can try to recover) deeply discharged batteries, etc.

Thanks to all these features, the NOCO GENIUS10 10A Smart Car Battery Charger is one of the most popular battery chargers in its class.

Of course, such a battery charger doesn't come cheap, but neither are the batteries it is intended to recharge, maintain, and recover.
