Default Battery replacement - preferably lightweight

So i tried to search for a while and couldn't find a thread under like 8 years old. My optima red top, while starting the car fine, is over 3 years old and tested bad. I live in michigan so it would see potentially below 0F. What options are there for a good battery that would survive under the hood in hot and cold enviroments? No aftermarket stereo system or anything like that. I was looking at the odyssey pc680mjt, but it says 170 CCA? That seems extremely low to start a car reliably. Id prefer the battery be below 20lbs, even lighter if possible, and have no issues starting in the cold. What do you guys run in your cars that see cold winters like mine? I searched for hours and cant find any recent information, maybe i suck with google and the search button

I have a 680. It starts the car fine, but I kind of doubt it would be enough in cold weather.

PC680 is fine for where you live. Just make sure you get a good one - you'll know within 2 days. Odysseys are great when they work... but many fail right out of the gate in my experience.

There is some sort of higher burst crank amps for 5 seconds on the PC680. Mrsaturn, were you commenting that it is fine for me down south where I don't have a true winter or it would be ok for SpartanCP in detroit?

I don't think that battery is going to cut it for you. Not enough CCA. I'm just using a FVP battery with 585 CCA. Bought it last year and haven't had any problems with it yet. I live in Nebraska and we do get cold winters.
If you want to get a good battery you should look into a good AGM battery. I've always had good luck with Interstate batteries.

You might not think it will cut it for him, but I know it will as I've been running PC680's for years without issue (including freezing Winters).

I was talking about Detroit - even in Winter, the only issues I've had with Odyssey batteries is having a few duds on day 1 or 2.

The PC680 will be fine IF you have it on a charger on really cold nights. Ive had my 680 in my cars for 5 years going and its only failed to start twice, both times the car sat for 2+ days in single digit weather. Its never given me a problem in 20-30* weather, but if i have to let my car sit for more than a day or two i run a battery tender out to it.

To be fair, 0-10 deg weather for 2-3 days will probably give issues with anything beyond deep cycle marine batteries.

Random thing to note but relevant - I just returned from HK/China after about a week. PC680 fired up the Subaru just fine and a 1 year old, full-size battery in my beater Civic was deader than a wedge.

GrimmSpeed battery holder and Odessey PC680 is what I have and I’ve had no problems. If you’re going to be away any vehicle should be on a trickle charger but your DD you’ll have no issues.

Thanks guys, right now my battery is still showing 100% charge while testing as a bad battery so im currently running it until i figure out if i need a new shortblock next week. If my engines good, ill likely go with the odyssey. I have a charger/portable jump starter on hand incase

Get it from Batteries Plus if you've got one local with the 680 in stock (preferably 2-3 in-stock).

They have a no questions asked swap-out policy if you get a bad one and again, in my experience, there's a lot of bad Odyssey batteries just sitting on shelves. When you get a good one, it'll last - the bad ones will let you know in a day or two.

Default Lightweight battery - Tomioka TR-B1500

Does anyone have experience running a Tomioka Racing TR-B1500 battery? The specs look very promising, but I'd like to hear from someone who has used it before.
465 CCA, 15 lbs. Seems to be much better than stock (390 CCA, 34 lbs) on paper at least.

Shorai LFX36L3-BS12

You can hold it in the palm of your hand at 5-6 pounds and the lithium batteries have a lot of cranking power compared to the other small batteries.

Cold starts are solved by turning your headlights on for a bit or cranking a couple times if necessary as the battery gets stronger when it warms up.

I'm not running my car throughout the winter though.

As an aside I ran a PC680 for years, year round in cold temps. If you drive it every day you'll be fine as long as your car starts reliably.

ayy can we get a uhhhh bump

What other batteries will work with the GS kit aside from a 680? I'm not going to replace the ****ing thing every time it decides to **** out in no time at all. I'd rather stick with a quality product.

I was looking for something like the PC680, or a battery relocation, but I decided to use an Antigravity battery. That link is to the battery I use in my 2009 STI. I've only had it for one year, but it's been good.

The car sits for weeks without any use, and I've never had an issue. I live in Milwaukee, and ice race, so the battery has experienced some cold conditions.

The weight is startling, it's so light. I have a tiny Shorai in my BRZ, and that weighs a little bit more than the Antigravity battery.

I use a U1 sized battery box in the stock location, and the box is a little large for the battery. All of my intercooler piping and Cobb sensors fit around it without any space issues, though.

Do you know the differences between the Odsyssey Lightweight battery they sell on Rallysportdirect and the anti-gravity?

I'm trying to understand if there's much of a difference. For my application, my 16 STI is a track car that see's DD, but is not the main DD.

The price difference is quite substantial.

Why exactly did you chose the anti-gravity one?

Regardless of which battery, i was going to put it in this - https://www.grimmspeed.com/lightweig...08-19-wrx-sti/

The Odyssey PC680 is an AGM battery, which is more traditional. I had an Optima redtop, which was heavy, but was also AGM and worked fine for 6 years as a DD, occasional track day car, and ice racing car. I like the AGM due to deep cycling capabilities, and they are shock resistant. The Optima was 35 lbs, though. The Odyssey was only 15 lbs and the bracket I was going to use was the Grimmspeed one, too. That would have saved me about 20 lbs in front-end weight, and would have been small enough to work in the standard location for a battery along with the piping and the sensor mount. I was almost final in my decision to use the PC680, but a friend recommended I look at the Antigravity lithium batteries.

I already had a Shorai lithium battery in my BRZ, and that battery was small, light and had worked very well for 5 years. My BRZ is my autocross car and occasional DD, so I know the lithium battery can take intermittent use, and extreme conditions, without any issues. My Shorai lithium battery, model LFX36L3-BS12, is about 5 years old now, 4.5 lbs, and has 540 CCA (supposedly). I had good experiences with it, so I decided to look at other updated lithium batteries like the Antigravity.

The Antigravity ATX-12 HD is lithium, literally is 3 lbs, and was rated for 480 CCA. The Shorai needs the Shorai specific charger if you drain the battery, but the Antigravity can use other modern chargers if you need to. Plus, the Antigravity was less expensive than the Shorai. I have been getting serious about turning the 2009 STI into a track car, and thought losing the weight would be helpful, so I was convinced to try it out.

I can say that the Antigravity battery has been very good, and has dealt with heat issues I couldn't imagine when I first started being serious about tracking the STI. I know the whole engine compartment doesn't get to the same temperature as the area by the headers, the uppipe/downpipe or the turbo, but I'm certain it's been very hot.

So, knowing that lithium batteries are small, powerful, light, and can work well in challenging conditions led me to select a lithium battery, and the Antigravity batteries were a good example of that type of battery.

Sounds like we're in the same boat. I'm starting to turn the 16 STI into a more dedicated track vehicle so i'm also considering the antigravity. The only issue i can see is that i still have my car audio/amp hooked up to the battery from when i used to use it as a main DD.

Ideally, i'd like to keep the amp (Which runs my speakers only) installed as it still isn't a dedicated track car and i drive it 2+ hours to the track (Gatta have the beats going at 4am). I also run a self-powered little rockford fosgate sub which i like to add when it's the off season.

Do you think the antigravity would be fine with the audio hooked up? If so, i think it's getting added to the list once the cars back from the shop.

The alternator should power reasonable stereo equipment while the car is running. There is a possibility that there could be a bad interaction with the lithium battery, though.

In recent year WRXes, and just the WRXes, the charging system voltage regulation doesn't keep the Antigravity batteries in the correct range while the car is running under heavy load, and the Antigravity batteries may experience failures. I've seen a few WRXes at autocross have this occur. This has not been an issue with the STIs, but if you have an upgraded amp, I don't know what could happen, though.

I wouldn't depend on the Antigravity battery to have sustained power output with an upgraded stereo if the car is not running, though. Not directly comparable, but the Shorai in my BRZ drops power quickly when I listen to the stock head unit with the car not running.

The good thing about the Antigravity battery is the automatic shutoff if it drops voltage, and the ability to use the "restart" feature to use reserve capacity to get the car started.

Okay that's good to know. I don't think I've ever listened to the radio with the car not running, nor do i plan to, so that issue shouldn't come up.

The audio itself isn't anything crazy, just your typical speakers powered by mid-tier amp running like 75w-100w per speaker.

and a descriptions that repeats itself 3 times. on 3 features.
Napa has some ok stuff. but I'd choose a Subaru battery or legimate AGM battery over a napa.
I have been using Odyssey on my rock crawler (10yrs) and now my 08 wrx 2yrs) , sadly I wreck the batteries before it provides a decent life past 5 yrs. though on the upside, even though I wreck the battery by discharging the battery past its point of being able to recover it , meaning down to 5volts. I have recharged the Odyssey and though it wont last sitting past 5 days it does keep started each day.

I had one in my R100RS for about 6-7 years...two actually. They worked well, especially above 35F. I did replace it with the bigger battery because I ride this bike in the winter and if the bike was outside and it was less than 35, the PC680 would crank pretty slowly. Several times I had to push start the bike. This only happens after the battery was at least 3 years old. So I now have the larger battery which is about a year old: no trouble starting in the cold this winter. I have one in my oiled and the 680 last 3-4 years before I start getting ABS defaults.
