Umm... Voltphreaks = $$$$$$$$$$$$$$$$$

This option saves weight over stock and is 1/4 the price of the VoltPhreak's battery.

Unfortunately, in lead acid, LBS = AH capacity to first order. I really doubt they are really getting 52% more capacity in the same weight as a PC680. If you look at most LA batteries, they get 1AH per lb. This one is claiming 1.5AH per LB.

Not saying it won't work, I just don't think it's really 26AH, at least not when tested the same way the Odyssey or Braille batteries are.

yeah - i picked mine up for a dollar a pound, expensive true! - but i have to also say that i have had no issues what so ever - it can go 2 weeks with no charge and starts better than the stock battery ever did - starts the HID when car is not running etc...

I think you meant a hundred dollars a pound, right?

I just wanted to post an update.

I have had ZERO problems with this battery. If my Exige sits without use, it lasts about twice as long as the PC680 it replaced before I have to add a trickle charger.

Starts like a champ.

Extremely good bang for the buck!

I may put one of these in my Elan. Does anyone have a source for the adapters that go from regular battery "post" ends to the screw ends that are on this battery?

Google turned this up:
SLA Battery Adapter Connectors

Search for "Odyssey battery adapter" but be warned - the socket head cap screw in the adapter is captive under a threadsert so it might take a bit of fettling if the threads on the captive screw and the battery don't match up.

I dont drive my car that much. Can this battery qball mentioned last longer than the OEM battery? My concern is more on the longetivity, not weight. What's a few pound for me if I can't drive it after a week? I am skinny dude anyway, so it's already compensating, hahaha. :)

The odyssey 925 is what i use in my Elise and most of the LOONYS that own an Elise.

i just started up my car after being parled for almost 2 months. Started rigjt up.

I only wanted to use this cheaper one as I did not want to spend that much on my elan. i still think the odyssey is the way to go on the elise.

In your circumstances you need the largest capacity (AH) you can find.
See schedule in post #8.

Qball,

Sounds like a winner my PC680 lasts almost a week now.... I would worry about weight, but with the amp in the trunk.....

I just wanted to post an update.

Hmm.. What's up with Voltphreaks?

Their LiFePo4 based batteries carries an insane price. VPH700 (14Ah) @ $1,220 ?

Say they are using LiFePo4 1200mA cells, that's 40 cells combined. Each of these cells cost about $0.99 from my source, and that's proper quality with high discharge. Cheaper ones can be gotten for half that and less.

What exactly is driving up the cost of these batteries? I mean.. c'mon.. under/overcharge prot. and discharge circuits cost? ;p

Edit: http://www.valence.com/sites/all/themes/valence/pdfs/U-Charge XP Data Sheet.pdf 40Ah @ $890 incl. CANbus datamanager.

Qball, How long is the longest you've left it and had it start up?
