Lightweight Battery Options...
Lightweight Battery Options... So I need a new battery and want to move it to the trunk while I have the drive train out. I want a lightweight battery as well.
I have been looking at this battery
http://products.batterytender.com/Ba...t-Battery.html
Voltage: 12V
Lithium Cranking Amps: 360
Lead-Acid Replacement Range: 21-24(Ah)
Case Dimensions: 6.49” (165mm) length x 3.38” (86mm) width x 5.11” (130mm) height
Operating Temp: 40 - 140°(F)
Weight: 2.6 lbs
Also looking at this one

Voltage: 12V
Lithium Cranking Amps: 480
Lead-Acid Replacement Range: 26-35(Ah)
Case Dimensions: 6.49” (165mm) length x 3.38” (86mm) width x 5.11” (130mm) height
Operating Temp: 40 - 140°(F)

The car will never see cold weather driving and will be stored in heated storage in the winter.

The “LCA” is a bit of a BS term as there is no standard for test temperature I’m aware of. It’s used to describe the max draw on the battery without damage in ideal situations. Usually a trunk mounted battery with 8ft of cable between the battery and the starter is not an ideal situation. Esp if it’s even remotely cool temperature wise. (night racing)
The CCA standard assumes 0*F for cold cranking power listed. The "Battery Tender" units you mention won’t put out diddly at 0*F. Which as you mention might be ok for your application, though I was disappointed with the “tiny" batteries on my race car.
Personally The PC925 odyssey is my pick. Little heavier at 26lbs, but packs a lot of punch and is VERY reasonably priced. You can find them for $150ish shipped. My last battery was still going after 6 years. I replaced it for peace of mind recently. Used them many times on many vehicles without issue.
I also ran the smaller PC680 odyssey similar in size to the ones you linked but more powerful. 70* ambient temps and under it didn’t like cranking my 9:1 LS 5.3. Battery mounted in trunk. The PC925 had no issues. I’d suggest at minimum to go with the PC680. If you find the PC680 isn’t quite enough, you could buy another and run them in parallel.
Good luck!

Deka ETX 30L works great in my C5. 438ci 13.7:1 compression. Sat most of the winter with no tender and fired right up on E85. Ran it all summer no tender ever on it, routinely sits for a week or two at a time with no troubles.
This battery is 21 lbs and is relabeled by Braile as a 550ca unit I believe. Best part is that you can find them for about $125.

OP there is another lightweight battery thread in the drag race section.

I have bee using a 13.5 lb dyna-batt for 4 years and 40+K miles for my 5.3. I even let the car sit outside during the winter and it has always started right up, even after sitting for a month or two.
I have it mounted under the headlight area in front of the passenger front wheel and the cables have to run to the rear of the car where the engine is.

I really want this for a while now. $600 but it's under 10lbs and has 1000 CA. Also has a emergency shut down and allows for a jump start within the battery by pressing a button, it's just too much $$ for me.

Too many things to consider when choosing battery cranking amps. Some starters are more efficient, temps, engine size and friction etc. I think a stock 5.3 uses a 650-700cca battery. I run a 725ca battery out back with 12ft of 1/0 gauge wire that feeds the stock 5.3 2 gauge power wire and haven't had any issues. 500 might be enough for 1-2 good cranks. Lithium batteries get better the warmer they are. I ran one in my Suzuki 600 and the Shorai lithium battery was awsome, I use it for remote battery testing or jumping and it weighs like 1lb but has 210ca

I had an SX (I forget the #) in my 72 chevelle, had a 6.0 with a Procharger.
I wanted a tiny bat. I could leave upfront, moved under the fender near where the orig one was. The 72 was my first non blowthru, so FI was a new deal-On my first test drive it was a disaster, prob had to restart it at least 10 times in a row just to get it up the driveway and back in the garage.
I was amazed it didn't die, just kept on working. Made a believer out of me
