Hello,

I am looking to move away from my pc680 battery

I see people say miata batteries = prefer post's on other ends
or
grp 51 batteries = costco/interstate grp 51 is too tall, they measure ~8.75"

nobody claims to have a miata battery in-store locally when i call to measure up.

what make/model miata batteries are you using?

any chance that someone can i.d. the battery in this pic?



i dont mind making a battery tray & not interested in moving the battery to the trunk either.

 

Hi Aby

We have a couple of good battery threads in the motorsports section. Heres a recent one regarding Lithium's

BTW, Been on the PC680 for years & works for me

This little battery is tough as nails. I had one for 5 years. Let it die over and over and it kicked butt until it didnt. I replaced it with an Odessy, treated it the same and it took a crap in 8 months. Went back to the Shuriken, still let it die all the time and it's still working great.

thanks for the links

 

I reccomend a ETS Battery. Same size as odyssey pc680 but has about 300 more cca

 

thanks 4b11

how long have you been using the ets battery for?

my pc680 began struggling after 2 or 3 years, on really cold mornings on e85

 

Ive only had it for about a month or two. My odyssey lasted over 3 years but towards the end of its life it was garbage. It left me stranded 1 too many times so i contacted ets and they recommended there battery.

So far so good. i live in SOCAL and i am on e85 also but as you know we dont really have a winter here.

ETS: 480 cca
Odyssey: 170 cca

So the ets pushes out 310 more cca.

The only downfall is its a little heavier but........

Oh and ets is only 99 bucks.

 

I also had a group 51 battery and my car wasn't too happy about starting on the Infinity. I have a EFI battery tray that I trimmed to work with ETS short route piping. You may not have to trim it if you are using an open filter. I moved to a Odyssey 1100 and things got much better on the Infinity .Now with the MoTec it starts like a stock car.

i'm using the shorai lithium iron, as is heel2toe. 5lbs. huge cca. no issues here, but my car is always on a trickle

 

link please?

 

Using a full river Hc20, extremely good battery will do 680CCA for 5 seconds. And flat rated to 310cca after that time. Only issue is they tend to go flat rather quick, but a decent 10AMP charger kicks her to life easy as.

 

This is the one: https://shoraipower.com/lfx36l3-bs12-p130

I've had great success with that battery for almost 4 years now. Also, Shorai as a company is awesome to deal with so another reason to support them and buy their stuff.

5# and 540CCA. Think it cost me about $260 and then you just need some terminals which you can probably reuse from your current mini battery if you have one. As for the battery tray I just hacked up the OEM one but even that isnt needed.

 

they'll come with terminals, cushion material. i just had to buy one tie down, which i purchased stm's as it was the only one thin enough. then reused oem mounting tray and tie downs because lazy because cheap

Best thing I ever did for cold weather starts was step away from the mini-battery.

This is the Miata battery I used:

Duralast Gold 8AMU1R

I fabbed up my own battery tray, fits with the ETS short route upper IC.
