Lithium battery with 1 year standby? wtf?

[steve]

How is the PC680 battery going? How does it like starting when youve left the car parked up for a couple of weeks?

When mine was brand new, it'd wouldn't start the car after about 7 days. The only load on the battery while the car was parked was the alarm. After about 2 years, it was only 3-4 days before it would need a jump start. You'll want to make sure your cold start is spot on too, even when it was brand new and fully charged, it would only crank the motor (~9.2:1 static cr) for maybe 10-12 seconds before it needed a boost.

Once I went to E85, I bought an optima d34. Starting in winter on e85 with cold plugs was too much to ask of the little PC680, so I had to upgrade. The optima has subsequently shit itself (only holds charge for 2-3 days, even disconnected), so I'm on the lookout for something new - I think it'll be whatever sealed battery the local sparky has this time around.

Yeah me too Steve... the Optima D34 yellow top was a bit of a let down for me too. IMO it was a waste of money, plus also I bought a charger to keep it on trickle charge which also costs extra $$.
Im thinking these 'deep cycle' batteries arent really meant to be used as a main battery for a car, but rather for sitting there providing power for extended periods of time with the engine off (like stereo competition, camping etc).
The small batteries are lightweight and will start the car, but as you find out they dont last that long parked up without requiring a recharge.

Is it too much to ask for a sealed battery that we can pop it in the battery box in the boot and not have it go dead on us in 2-3 weeks? I know with just a normal calcium battery it can sit for weeks and still crank the car over but if you are going to leave it for longer then hook up an automatic trickle charger to it so it doesnt go dead. Those new european VARTA brand batteries look the go too. So many to choose from.

Whats wrong with the maintenance free batteries you buy for $150 at Kmart/supercheap etc? im sure they don't need to be vented

Those Optima D34 yellow tops are shit, mine also dies after a few months, just reading up on it, they are only good for cars that are being driven all the time, the D34 Red tops are much better

Optima Red Top - High performance starting batteries for high performance applications.

The RedTop delivers superior starting power and provides greater resistance to vibration and extreme under bonnet operating temperatures.
The range is commonly used in high performance vehicles, utes, luxury cars, 4WD’s and other applications where a long lasting, high power starting battery is ideal.

My PC680 has been working great for a couple of years now. The car spends more time sitting stationary than it does moving and I don't trickle charge or ever had to jump start it.

Car has cranked over each and every time (touch wood now that I've said this!!)

[bazeng]

Shayne, you probably don't have any draw when the car isn't running though. No stereo, clock, alarm?

My pc680 and now pc925 does not hold. I have to kill switch the thing everyone i park the car.. Current draw from my alarm (pager).

[Geo&Kez]

I use this Full River dry cell in the race car

http://www.allpurpos...&products_id=16

As with bazeng, I have to kill switch it because the Tein adjuster unit is drawing 250mA with the ignition off. But it will sit for over a month and crank no problems.

[EVL20T]

I had to post this up lol

Try 2 batteries

+2 on fullriver.
mate of mine has had the same hc75 fullriver batt for 3-4 years now an never had an issue. first it was in his daily/stereo comp car an now its in his turbo datto ute that only gets used once a week or so.

its the only brand battery i will use these days, getting good prices on them helps that choice

[Evo-00x]

Fuk me.. that FullRiver HC75 is $400 and weighs 25.4kg!!

[barcode]

thats full retail i do them cheaper than that but the weight is something i cant do much about lol.

they do smaller ones obviously i only pointed that one out as that is what i will be using in my rvr as i will have a large stereo in it

[Evo-00x]

Actually eyeing off the FullRiver HC35 and HC44 at the moment. Im sold on the screw on terminals as well.
HC35 (35ah 438CCA) vs HC44 (44ah 560CCA) only $30 difference.
Not getting Optima ever again!! lol

[DOUGMO]

I received my shorai, holy shit, 2.2 kegs is really bugger all.

Should test its ability in the next week or so and will advise

[jack be nimble]

Just got a lipo battery for the bike to test it out $170 weight is 700gm rated at 140cca. Its light like its a empty cardboard box unreal. Measures 150x87x105mm

But they list a 290cca (same physical size) at 1.3kg and a 360cca 175x87x130 (1 inch wider and taller) at 1.6kg.

Unbelievable light!!!

[jack be nimble]

Its standing on a std a4 glossy brochure the tape measure is actually heavier and shown for size

Hope it works good.

My pc680 has been fine so far btw
