I installed the Braille Auto Devepolment B2015 all-season lightweight battery and the power protector that came in for free when I bought it. the power protector monitors battery voltage and usage with the vehicle running and when it is turned off. If it senses that the usage of the battery when the vehicle is turned off will exceed the amount of power needed to start the vehicle, it will disconnect the battery and protect it from being drained. it came 2 remote actuators to reconnect the battery in the event that it decided to disconnect the battery due to possible battery drain. also a set of wires and a fuse were included to bypass the power protector so you're alarm stays on even after it disconnected the battery.

Volts: 12 AH: 21
Pulse Cranking Amps: Over 1060!
Exterior Size L:6.8" W:3.8"H:6.1"
Weight: 15 lb


before...


after...



...so far it's holding up pretty good, I parked it outside las night and tried to start it this morning and it cranked right up.
I'm driving to Seattle, WA sometime next month. I'll find out how it really is an all-season battery.

 

Nice to see the battery in there. I'm wondering, will it move around in the housing under strong g forces?

Also, how much was it?

 

anyone know the weight of the stock battery?

 

I used the same hold down on my genesis light weight battery that's on my AE86 and I use for driftdays and SCCA solo 1.
...I paid $169.65 for the battery, the free power protector and shipping

deedub, the stock battery on my car was 36 lbs

 

you definitely need the power drain protector in the RX-8, mine goes dead in a week or so if I don't pull the ground cable off, it often sits several weeks and has racing accessory drive pulleys that don't put out much alternator juice below 5000 rpm

 

do you have the same battery?

 

very nice!
is the power drain protector only free at this time?
or is it always thrown in the package for free?

 

the power protector was free for the month of september, I don't think they offer it anymore. I would check back evey once in a while 'tho...

btw, how far are you from Hurlburt Field?

 

Mine was sitting for three weeks this June and started immediately after that - in fact, there was no difference between before and after my vacation. So I'd say, this problem is definitely not a generic RX-8 one.
I had the car sitting for two-three weeks a few times before - never a single starting issue, and I didn't even have the new starter back then.

 

thanks for the info!
never heard of the place... i'm in miami.
why do u ask?

 

nm, I was gonna ask you how far is it from Sarasota. 'cause that's where Braille Auto Development is located. I might try and get another battery and a charger when I fly over to Eglin Air Force Base next month but I found out that is almost 350 miles away

 

Damn, that's tiny! AGM batteries are amazing. With only 21AH capacity though, auto cutoff is definitely a good idea.

 

CCA 360 ....

With NYC's cold weather .... I cannot live with this battery.

 

lol why do you wanna live with a battery?
that's for the 11.5 lb battery, this one has 425 CCA's. still not a lot but works for me being in CA
...I had the smaller battery on my FC when I was in WA and seemed to work fine during the winter.

 

I believe he does, yes.

Hey... your mounting kit looks way better than the one braille sent me. I was wondering why mine was looking all wrong.

I'll call them on monday to see whats up. They had excellent service when i ordered it, so i'm sure they'll take care of this.

...I didn't order the braille mount, I just bought an adjustable battery hold down from Schuck's/Kragen.

 

link me!!!

is that a local shop or did you get it online? It looks like exactly what i need. Do you have the same braille battery as me, the 11 pound one?
