I am using this Odyssey battery on my XLRG, 300hp IO-540, works great, small size, mounts any direction except upside down.

Tech Tip: Special Installations
Mounting flexibility is one of the Odyssey battery's strongest features. It may be installed in just about any orientation (the only exception being inverted) without sacrificing any of it's world-class performance attributes. Have no fear about acid spillage-- the battery recycles internal gas during operation/charging and the valve regulated design eliminates the need for an acid vent tube. All in all, this offers two awesome benefits:

The battery can be installed in applications where it wouldn't normally fit. Just flip it on its side and fit it into your battery box ("L" terminal adapters, which are sold separately, may be useful for ease of installation in these cases... be sure to double check your application!)
The lack of acid eliminates the fear of acid burns or damage to your expensive chrome and paint. You're installing an Odyssey battery because you love your vehicle. You shouldn't have to be concerned things like leakage.
2 Batteries in 1

The Odyssey PC925 battery combines in one box the characteristics of two separate batteries. It can deep cycle (be recharged) as well as provide enormous cranking power.

Military Grade

Only Hawker Odyssey batteries are based on the same battery technology offered by Hawker to the military for aircraft and tank batteries. Odyssey batteries are of military grade and have endured rigorous tests that demonstrate their overall ruggedness and exceptional tolerance of mechanical abuse.

Superior cranking and fast charge capability

The 5 second cranking power of Odyssey batteries is double to triple that of equally sized conventional batteries, even when the temperature is as low as - 40° C. Also, with simple constant voltage charging (alternator or independent charger), there is no limitation on the inrush current, so the user is assured of a fast charge.

The chemistry and physics of lead acid batteries is well known and the variations between similarly constructed batteries are more a matter of small degree, but can easily appear to be large differences based on statistical advertising, difference in how the capabilities of specific batteries are presented, or comparing one kind (or sub-kind) with a different kind or sub-kind.  That said, to avoid arguments, I am talking about similarly constructed batteries within a specific class and type, as having only small differences from each other.

If you really want the "ideal" battery for an aircraft (from a physical characteristics perspective - light weight, GREAT amp draw capability and good reserve power), go Lithium - but also be willing to pay the much higher $$ price (sticker shock) and you will also require special changes to your charging system to handle the special charging requirements, cell balancing and to deal with the fire hazard.  A lot of AGMs (other batteries as well) are good for both starting power and reserve power (supplying power at a constant discharge rate and being able to supply that power for a sustained time period), based on a compromise plate thickness. Thickness of the plates determines whether a battery is a deep cycle battery (lots of reserve and staying power but not meant for starting large engines) or a starting battery (short bursts of heavy draw), and compromises can be made here like in every other desired feature/aspect, by the manufacture choosing a compromise plate size.   Keep in mind, however, that you can easily ruin an AGM battery by how the battery is charged - you really need a newer smart charger that has an AGM setting on the charger or you can kill one in short order.  Also keep in mind that "momentary amps" is NOT the same thing as Cold Cranking Amps.   And that Amp Hours differs from Reserve Capacity.  You really have to compare apples to apples.  As noted by prior discussions here, the correct battery for specific applications  also depends to a large degree not only on the application (starting vs reserve power, or a compromise construction), but delivery of the needed amperage at the proper location as well.  Ie, wire size, distance from the place high amperage is needed, etc, and that the decision is also impacted by weight, weight and balance, cost, wire runs and their costs, physical size limitations, etc.

I chose this battery by comparing my needs, including physical size (it just fit my battery tray), with what I could find.  I wanted a good starting battery, but also one that could provide the AH rating that would allow prolonged power in the event of an alternator failure.  Cost was also a factor, but not the overriding one.  I am also very light weight (135 pounds) and enjoy flying solo, so needed nose weight.  This battery replaces a relatively new Odyssey costing over 2x the price with less capacity that died prematurely.
