Why a lightweight battery?
As many of us know, the OEM battery weighs about the same as a bungalow. (25Kilos springs to mind)
With the number of track days been discussed recently and our unholy obsession with knocking those fractions off the 1/4mile
many of us are willing to take reasonable measures to squeeze a few more ponies out or lose a few Kilos here or there.
Alot of us have resorted to TT lower (alloy) arms and hubs to save a few kilograms. I'm looking forward to fitting the NQS BBK from DaveB
to shed alot of weight form my brake setup, along with air con removal and the plan of carbon bonnet should be a sucesful diet!
Where from?
I have been in contact with Paul at Linden batteries;
http://lindenbatteries.co.uk/braille-batteries/
Linden Special Vehicles
Booth Drive
Wellingborough
Northamptonshire
NN8 6GR
Tel: +44 (0)1933 670982
He has been quick to reply to my E - mails and very helpful.
Fitting
They come with terminals and are ready to go (there are quick release terminals and side post terminals if you want those).
The extras you might need is a mounting kit or a bracket and hooks as the battery is obviously smaller than a normal one. Depends how you are planning to keep it in place and whether you can use what you have already.
I plan on mounting mine in the OEM position for the time being. If positive results come from the new ITG inlet (that requires more space) I'll shift the battery to the boot. This will require some cabling and access to the bulkhead ( behind glovebox)
Heavy duty velcro that people use to hold Subwoofers & I have used for my front number plate is more than upto the job. Linden Batteries also sell various mounting accessories.
Geeky bit

The battery that started the revolution – The B14115 is the most popular lightweight automotive specific battery on the market today! With a weight of only 11.5 pounds and plenty of power to start V-8 engines, see why racers and car designers demand this battery.
Braille Lightweight Battery, model B14115. Designed for daily and race use in most vehicle applications. With over 900 Pulse Cranking Amps and weighing under 11.5 pounds this battery will provide the power needed for most production vehicles and save between 20 - 50 pounds over a stock battery.
Technological features:
- Factory Sealed Valve Regulated Design Eliminates damage from Acid Spills
- Environmentally SafeHigh Density Oxide. This enables Braille to produce a "High-Cycling" lightweight battery
- Heat Sealed Top Battery Cover Eliminates Electrolyte leakage
- Absorbed Demineralized Electrolyte Improves service life and off-season storage
- Heavy Duty Automotive PostsResist Damage from Vibration of Heavy Use
- Easy installation
- Calcium Full Frame Power Path Grids Provide Highest Cranking Amp to Weight Ratio
- Lowest Self-Discharge Rate
How much?
I have chosen the; B14115 - Braille No-Weight Daily Use Battery (5Kg) (details above) So has RobH from SCN and here. Aaron66 opted for the similar spec TR battery.
The Braille offers significant weight loss at the cost of £134.99, Paul has offered 10% discount to Members of Mk5GolfGti.co.uk and SCN
making the cost - £122.71 inc VAT & next day delivery
There are Carbon versions for those of us with Hurdy syndrome :party:
Paul said if there is enough interest he can get the 'techies' to add a discount box to enter the Mk5gti discount code, for the time being a quick a call and mention of this thread will suffice.
My order is placed and I cant wait to get it fitted! Shame I have to wait until I get home to Uk next weekend to pick it up form the in - laws :sad1:
I will point RobH & Aaron to this thread incase they have any points as Im sure Ive missed something.
Review to follow!

:popcornsoda: interesting, looking forward to hearing about day to day use of the car with this fitted :happy2:

interested in one of these, is there an e mail for paul at linden - have a few queries

Danish - I have a 5kg version fitted, car has been left for 2wks came home and started no problem at all. Great bit of kit. Everybody should fit one. Stevie.

Stevie, out of interest. How have you secured your battery down?
-
+ 1? there must be securing issues.
-
The 'Heavy duty' adhesive velcro I used for my front no plates is hardcore. Said on the packagin it could hold like 10 - 15kgs to a wall :surprised:
Has survived 2 years of autobahn and pressure washer. Failing that there are mounts on the Linden site.
RobH is currently using a mini ratchet strap until he has time to sorrt a more permanent soloution
-
I am running the TR Performance battery? Recommend it. Will post up my battery tray if my photobucket works for me.
-
Fitted one of these yeasterday and the only difference between this and the oe battery is its 12kg lighter. Win win situation.
No issues with starting it this morning either :happy2:
Need to improve how ive mounted it which is this weekends job.
Rathect strap will be the permenant solution mike, will hold the battery in place easy.

Ill be shedding a few kilos next week; Braille battery, air Con pump out, NQS BBK :party: :party: Carbon Bonnet at a later date and I'll call the weight saving a day. Seats out for track days etc and mayyyybe a pole position for my side of the car (although I'm hardly 'the larger racer')

Not sure lol. It does weigh nothing. Look up the braille battery tray and have a look. :wink:

If every one showing interest in the batteries takes the plunge you could make a few quid knocking a few more out? :innocent:
Have you any pics fitted?

Dunno Mike i am super busy at work got a hell of a lot on plus training. One of the boys might take it up. I do have a pic fitted somewhere but the mrs is giving me f*cking sh*t for the amount of time spent on here. Will try post up in morn. :happy2: Stevie.

Argh, :drool:
You guys getting the coolest stuff, lol.
As far as I'm aware Braille batteries are not available in NZ, but I don't think car batteries can be shipped internationally.
Hmmm, will send the guy an email and ask. As my battery is about dead anyway. Great excuse to replCe the battery with a small one.

I've had a Red Top 25 for about 4 months with no problems. I just cut battery tray down and used a traditional over battery clamp, nice to have colourful battery on show lol. Defo a brill mod lad anything that can reduce any natural understeer.

Heavy duty adhesive Velcro?
Cant wait to fit. Booked in 1st Aug for cambelt so will be fitting then. Bought a plastic battery box as found in the Golfs and A3s (the Cupra comes with a poverty spec material cover)
-
Transfered funds this morning, fitting 1st Aug. :party:

I've seen the battery cages stuck on with epoxy resin, just don't press down too hard, so there's a bit of a gap to get a round/flexible coping saw blade in should you want to remove it.

Hi guys,
Paul at Linden here - glad you are enjoying the batteries. We also do Tomioka Racing batteries too which are just as good http://www.lindenbatteries.co.uk/tr-batteries/ (http://www.lindenbatteries.co.uk/tr-batteries/) Interested to hear about the velcro, wouldn't have thought of that!
GLIDN - yes we can ship internationally (we've got a customer in Italy) but it costs a lot to ship them outside Europe, about £75 inc VAT to NZ, which is getting pricy
Cheers,
Paul

i don't know if you've resolved the fitting problem but i was thinking possibly cable ties?
at work we used heavy duty cable ties that weigh nothing and could easily hold a battery in place as ive used this method before on a Machine when the clamp was broken by thief's.
Just a thought :happy2:

:happy2:
My fat battery is a 70 Ah type as well while I know A3 2.0 TFSIs just having 60 Ah.
Keep in mind ''Amp hours'' isn't the one and only. ''Cranking Amps'' is even more
important ro start an engine.
So if you don't listen to music while the engine isn't running I don't see any issue
reducing the Amp Hours radically.

Wrong link, David?
60 Ah is way more above minimum.
If you are careful 25 - 30 Ah should start every day.
-
15AH here :ashamed: Am careful and starts every day
-
No doubt, Mike. :wink:
But I wanted to be careful as well. Careful to recommend.
A Braille offers much higher crank amps than conventional batteries
and I kept in mind technically non skilled people reading this. So
better have some reserve.

Thought id find you here :p
After 4.5 - 5 days it didnt have enought juice to crank over.
Ive got an out door extension run outside the house with CTEK conditioner charger keeping it topped up. If you dont use the car much could use it just for 1/4 miles and track days?

4-5 days isn't ideal tbh, plus my car is parked about 30m from the house sometimes for 4 days+ without use
Interesting idea for the spare battery though

Found this:
As far as I know - All the CCA for the manufacturers is done at 0F, and the CA is at 32F, all this info is off the manufacturer website.
Acording to Autozone website the 240sx needs 360 CA.
So if you want 100% factory reliability even at 0F you want to be shoping around for something that will have at least 360CCA.
For those of you where the weather gets in the negative digits (F) you will want somethign that has a CCA > 360 at 0F
The battery I had in (Advance Auto Parts stock replacement stuff) weights 37lb..
READ THIS:
In BLUE are the brands whose CCA Ratings seems either off or make it hard to find their testing methods.
Deka Batteries are more than likely to be Deka ETX rebadged -- Their advirtised CCA IS PROBABLY NOT PERFOMED AT 0F.

Probably Deka rebadged
**no info on website on what Temp the CCA and CA test are done at...
DEKA:
Come with M6 Thread on terminals - you will need adapter to SAE automotive Terminals.
Rebadged as BigCrank, Braille and other brands // BigCrank has cheap price .
(Proved and discussed on the vwvortex there is a whole thread about it.)
Odyssey:
*MJT: Metal Jacket + Terminals.
Also the Odysseys have battery mounting brakets avaible.
Miata Battery:
Duralast rates them at 330CCA, Marathon at 320CCA, Westco at 475CCA,
make what you want of this info but personally I'm not getting a Westco Battery
Made by EastPenn Mfg.
Sold under:
Marathon MAR-8AMU1R (1Year Warranty)
Westco 12V31M (4 Year Warranty)
Duralast 8AMU1R (8Year Warranty - apparently WAS avaible at autozone)

I use Lipos in my RC planes (My job is selling RC toys LOL), have a 5000mah 11.1v in 2 of them and they draw 100A peak current anyway, Lipos are based on C rating, so you get 5A battery with 20C means it can offer 100A peak current, likewise a 5A 30c battery can give 150A if needed, although my own models tend to only draw 85A max on full throttle (That electric plane does around 140mph top whack :surprised:).
Larger planes you just put them in parallel or series to bulk up amp and mah capability, still they weight not a lot anyway, not compared to PB batts.
IM sire in years to come tyhey will be in cars, my golf trolley is also LIPO powewred now.

I know several people have l/w batteries so to add to this I have had a custom fabricated battery tray for the Braille / Tomika (they are the same dimensions) made by Alex at AKS.
This adds safety IMO as the battery is propperly secured.
Here it is before powdercoating and final features applied....

It bolts down in the original mounting points of the plastic oem battery tray :smiley:

Has anyone looked at a lithium for our engines yet? I'm looking at the options seeing as my standard one has just about had it.
-
google liteblox :-) Carbon bodied Li-ion goodness
-
I think i also need to google balaclava and shotgun! :grin:
The price of those is mental. You can get lots of lithium batteries for much much less in the UK. As mine is a strict track car it's going to get left for long periods unused so seeing as they only discharge 10% in 12 months they seem like the ideal thing.
-
Isolating it helps massively. I fitted an isolating knob to my negative terminal and could leave it for months.
-
I'm looking at something like this. It can be had for about £250.

Oh yes, It will be on an FIA cut-off switch when not in use so no problem there.
Is it really worth it though? I could get a small lead-acid battery for cheaper and use one of my trickle chargers that i have laying around. I need to check if they will work with the lithium...
-
Are you still using your small Braille battery Mike? I'm trying to justify the cost of a lithium but it's just not adding up at the moment. I'm thinking of going for a smaller AGM Braille
-
Only just recently sold it. Was good value for money. I'd recommend something with a higher capacity than I had though.
Was fine if isolated or used every few days. But the reserve for leaving lights on or stereo etc was non existent.
It was super light but only 15a/h

Think i'm pretty much set on one slightly higher than you had which is 23ah. As it's a track/race car there is no stereo or anything., I have stripped it all back to the bare minimum.
It comes in at 7kg but the weight i am not too bothered about. Its a great saving compared to the standard battery anyway but as i had to replace the factory fit i thought i might as well go for a smaller one.
I have chargers that i can use already for it and keep it topped up :happy2:

Measured my new replacement (Varta I think) one at 20kg
