I put in a Duracell group 49 battery ~ made a 3/4" plywood base/spacer with rubber on top to get the top up to stock height.
100 Ah
1105 cranking amps / 900 CCA
185 min reserve capacity
About $160
Group 49 FTW!
Been running strong since June 2020.
Spacer on top is 3/4 plywood cut to fit.

some things get better

some things are good and great just the way they are ,


my OEM TOYOTA TRU-STARTS , made by interstate here in the lower 48 , ALL group 27's F and NON-F , 2002 TACO Pre-runner has group 24 , im coasting on 10+ years average , by topping off with yes , Distilled water at each seasonal FALL maintenance time

- i also remove , polishes bright the top lead posts , w/ 220 emery cloth , then wrap it around my pointer finger , polish the inner rims , and use a ACID bryush and apply a MED. generous amount of this to both terminals and inside the OEM YAZAKA Japan terminals bands too , i swear , like 100 fols on the OEM YAZAKI red flex accordion boots at B+ terminal , and down at main starter lug , ALL locations get this :


- these 2 OEM japan Spec. YAZAKI service terminals are unique , there M8 Studs are a a TAD longer then other ones and BOTH have color keyed plastic bottom plates cover features to then , MOST i see on toyota's today DO NOT ?

- i DO NOT use serrated M8 flange nuts on the male studs , i opt for marine grade stainless steel smooth ones , my choice there , less mangle lees issues ...

- Fully Synthetic marine Grade Food Service di-Electric Grease

- this has been my approach and recipe for issue free , proper fit , form and function for since T-TEN in the mid 1990's ....

- that round cavity is where the M8 service nut goes , a little happy nest / keeper ...i like happy little keepers :) :wrench: :wrench:

- i use ALL these parts incorporated into my unique take on , my hand-assembled 40 , 60 battery cables too , factory FIT FORM and FUCTION , all japan spec parts too ! \

I don’t know the whole FOOD SERVICE end of this but it has a pile of uses …

Pick up a 6 pack of WEST SYSTEM EpoXy Syringes and a fist full of 7-11 coffee wood stirres , this is how I re-load them to precision inject all my male and female electrical connectors inside my Toyotas and out , bulb sockets too !

FWIW to follow up on this thread I started years ago, my Group 49 battery from Napa was great for the past 6 years and I never had any issues with it. I replaced it recently chasing down some electrical nuances and realized it was not the problem. I replaced it with another Group 49 Napa Legend Premium AGM.

I have the same battery. 3yrs old and after a week or two of no use it reads 12.3v or 12.4v, should I be concerned?
I eventually recharge it, but was wondering if this seems normal.

No, resting voltage is usually around there. It's normal.
 
For those running a Group 49 battery, how much space do you have from center of battery terminal to edge of top cap?

I have SDHQ billet battery terminals and they protrude out towards front of vehicle.

Thank you!

I dont have this setup so I cannot really comment on that. But one thing I see here which may or may not be good is that following - I can see this setup having a see-saw effect. Where the Terminal is being rocked UP like a see-saw "IF" the rear copper end is a lot heavier. Its like a torque effect. So basically make sure this screw on the "P" section is torqued down correctly. Hopefully not crazy tight where it can break the billet.

My group 49 battery is a Duracell from Batteries+

The measurement from the center of the positive post to the edge of the *raised* vent section of the battery top is exactly one inch.

The corners with the posts are essentially inset into the top of the battery - biggest issue would likely be being able to connect them only very straight as in your photo above.

I can see that with the shorter battery, fusible link weight, and bulkier billet terminals. Thanks!

Thanks for measuring. I'm at 7/8" from center to edge of billet terminal. Might be too tight of a squeeze especially if billet terminal is off centered on the post.
27F it is then.
 
Thanks for the picture. It probably would’ve worked but didn’t want to risk it. I ended up going with a Duracell 27F from Sams club to replace the Lexus (interstate) 27F.
