Odyssey PC925 Battery Series
Odyssey PC925 are sealed lead acid (SLA) absorbent glass mat (AGM) dual-purpose batteries, designed for marine, automotive, LTV, ATV and other applications.
Odyssey PC925 are durable, vibration and mechanical impact resistant batteries, providing good charging/discharging features in wide temperature range, being able to produce large starting current, tolerate large number of deep discharge cycles etc.
Being SLA AGM batteries, Odyssey PC925 batteries are low maintenance batteries that can be mounted in virtually any position.
Odyssey PC925 Battery - Features and Specifications
Odyssey PC925 battery nominal capacity is 28 Ah (when being discharged for 20 hours). Like all lead acid batteries, when being discharged faster, its capacity drops and when being discharged for 10 hours, its capacity is 27 Ah - it can deliver 2.7 Amps for 10 hours.
These values are very important when powering smaller loads like LED lights, fish finders, stereo units etc.
Reserve Capacity (value) is 48 minutes - Odyssey PC925 can deliver 25 Amps for 48 minutes, which is very important when powering medium loads, like smaller trolling motors and similar.
Despite being dual-purpose battery, Odyssey PC925 battery can supply 330 CCA (Cold Cranking Amps), 480 MCA (Marine Cranking Amps), 610 HCA (Hot Cranking Amps) and 900 PHCA (5 sec Pulse Hot Cranking Amps).
Due to its low internal resistance (5 mΩ), short circuit current is ~2400 Amps - such current can make plenty of damage, so avoid short-circuiting this and any other battery.
When being used in deep-cycle applications, Odyssey PC925 can lasts up to 400 cycles at 80% of DoD (Depth of Discharge).
Thanks to its design, Odyssey PC925 can be stored for longer periods of time without the maintenance. When being fully charged first, it can be stored 48 months at 41°F (5°C), 36 months at 59°F (15°C), 24 months at 77°F (25°C), 12 months at 95°F (35°C), and 6 months at 113°F (45°C). When being stored, as soon as the battery voltage drops down to 12 volts (35% of full charge), the battery must be fully charged, preferably with intelligent AGM battery charger.
Odyssey PC925 battery general dimensions are (L x W x H) 6.64 x 7.05 x 5.04 inches (168.6 x 179 x 128 mm) and it weighs ~26 pounds (~11.8 kg) - weight and dimensions depends slightly on exact battery model.
Odyssey PC925 Discharge Performance Data
Odyssey PC925 discharge performance data is given in the following table.
Note: Values are given for the battery being discharged at 77°F (25°C) down to 10.05 volts.
|Time||Watts (W)||Amps (A)||Capacity (Ah)||Energy (Wh)|
For example, people having fishing kayaks with small trolling motors (~20 Amps at full throttle) can expect ~1 hour of constant operation using Odyssey PC925 battery.
Also, people having fish finders, GPS and similar devices drawing 1.5 Amps can expect ~20 hours of constant operation.
