Ford manual does not reference group size that I can find.


Is the oem Motocraft bxt-48h6-610 battery, which is in above referenced vehicle, a group 48?

 

The 48 number in the service part number is the group size. Group 48 or what we call an H6 (being replaced by L3 terminology). Your truck is capable of accepting a group 94R or H7, but will require a larger battery blanket.

 

Thank you for the knowledgeable reply, stormsearch. I'd be interested in a physically bigger battery for the additional potential amp hours capacity (when properly charged, that is...).

Any suggestions, here? Perhaps a material source that we might MacGyver our own?

 

The OEM part number for the larger battery blanket is FL3T-10A687-AB. it is a service item. Otherwise, just cut the smaller one and protect the engine side of the battery. The material used is proprietary so is not available to the consumer.

 

i believe the 2.7 battery is larger than the 5.0s due to stop/start. The biggest motorcraft battery I see being spec'd is the BAGM-94RH7-800

 

Not only that, but its a AGM battery too I think?

For me, I trailer dirt bikes into BLM land on bad washboard road (battery vibration?) for 7 days at a time. Truck Accessories are run a lot, and theres the small chance the battery will just up and die by internal short - has happened twice to me before on other vehicles. And once a battery suffered a small crack and leaked acid - that was fun to deal with.

So, I plan to lug an extra AGM battery around that will "drop in" existing tray.

Those antigravity lith-ion xp10's dont crank a totally dead battery, only last 2-3 yrs, and there is some concern about storing one inside a vehicle during summer months.

 

They are AGM, not cheap either! MSRP $200.00

 

I have two AGM's on other vehicles. I think they're worth it.

Google around to see the advantages of AGM.....yea they can hurt your wallet a little.

 

Most expensive AGM batteries are a solid investment IF you can recharge them fully at every opportunity. They don't like to be left in a discharged state much more than 24 hrs... The particular battery maker (Odessey, for example) can also require a higher voltage setpoint (14.7 vs. the common 14.4V) for the absorption phase of charging (from roughly 80% SoC to 100% SoC) and the absorption phase takes TIME, typically 4 - 6 hours! and sometimes this slightly higher voltage requirement is more than what an automotive alternator can output.

One remedy for charging an expensive AGM when spending multiple days stationary in the remote outdoors is to use a 100W solar panel, a solar charge controller with some adjustability, a good fuse and some good-sized copper stranded connection (minimum 10 to 8 AWG).

The other is the purchase of a good quality, microprocessor-controlled *smart* charger to top off your new megabatt at least once a week at home.

I use a 100 amp hour Odessey, a Group 31, as a power source for an Engel fridge in an unfinished camp trailer project of mine. I have learned how to keep this battery healthy as per Odessey's recommendations and have built a portable solar charging setup similar to what I've just described.

 

I did my final project in college working with one of EnerSys manufacturing facilities in Missouri. The same process that makes their Odyssey series of batteries is used to make the batteries used on Nuclear subs and in tanks.
