odyssey pc 680 battery longevity
How many years use could one expect from an odyssey pc 680 battery?
Car is hardly used (lets say 10 drives a year) but battery is disconnected by battery cout off switch.... and no it doesnt get trickle charged.
Was showing 12.45 v. Stuck it on a charger that after a few mins dropped to measure charge current of 0.7a, ..... doesnt seem right somehow..... new
battery time i think.
Anybody used enduroline equivalent, is £17 cheaper.

Charge the battery for several hours, then let it rest overnight and do a cranking voltage test.
Anything over 10.1 volts when cold cranking the engine is good, but it won't give you any indication of the remaining amp hours capacity left in
the battery.

Typical lead acid battery will lose around 10 - 15% charge every month just standing on a shelf, if the car's not getting used regularly one of
our li-ion units would probably be only a touch dearer than the PC680 & they don't even drop 5% standing for a year, they should also last
around 2000 cycles rather than typical lead acid at 300 -500
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

The Odyssey doesn't like a constant load eg Immobilizer and when they go flat they don't tend to recover very well in my experience
Been hearing good things about Li-ion batteries

I replaced the PC680 in my car with a Li-ion unit from Russ...I haven't touched it in 3 -4 weeks and I can guarantee I could walk out to the
garage and it will start on the button. They are very good and 6Kg lighter !

One point that hasn't been mentioned is battery voltage is greatly affected by temperature
A fully charged battery at 22c will show just under 12.65 volts, a 75 percent charged battery 12.45 volts
At 5c these voltages drop to 12.6 volts and 12.4 volts.
A modern plastic case lead-acid battery in good conditioning with zero load will suffer from about 3 to 5 percent loss of charge per month from
self-discharge. You may see higher numbers quoted but things have moved on.
Modern tintops discharge have parked-up parasitic current drains of 30 to 80mA so leaving one unused for more than 14 days or so could lead to
problems.
Modern way to test a lead-acid battery is to use a battery analyser, I have a Ring brand one that gives estimated charge capacity cold cranking amps
and remaining percentage life of the battery.

Ditto this. Mine was in the car for a couple of years while I built it, then I used it for a year and the battery died

I've had mine 6 years and it starts first press of button. However it is trickle charged approx 50% of the time ( when I remember)
You'd be surprised how quickly the sales people at B&Q try and assist you after ignoring you for the past 15 minutes when you try and start a

According to Odyssey the battery will hold a full charge for two years without loosing any charge.
They definitely do not like being fully discharged

As others have said, Odyssey's do NOT like being fully discharged. A mate with a lightly used Locost here has so far killed 2 of them with the
drain from the immobiliser He's now taken to doing what a LOT of other Odyysey users here in Oz do - using a Ctek intelligent charger to
keep the battery topped off while the car is parked up. Ctek also make a nice little dash mount socket, complete with status lights, so you can plug
the charger in without even lifting the bonnet.
I'm not a salesman for Ctek  - just reporting on the success others have had with them.

No batteries like being fully discharged, even traction batteries & I would be the first to admit that one small downside of Li-ion units is that
their actual storage capacity for a given CCA current is lower than a similar CCA lead acid, hence always best to trickle charge if there are constant
drains like immobiliser/alarm etc.
With most kit cars, once you turn the ignition off there is nothing to drain the battery as very few of us have alarms/immobilisers, in that situation
the Li-ion will outlast the lead acid many times over

My previous PC680 lasted 9 years. Was totally discharged once. I used it 10/12 events a year, on an Optimate conditioner the rest of the time. No
problems until the end. Replacement working fine also, bpught in 2012 for £92.

Maybe its not as bad as i thought. Had it on charge yesterday until 9 pm then again this moirning and it was able to turn engine over with no sign of
ffading so cant be totally knackered.
On charge again, will see if it holds charge. Need to looiik at points as getting no spark. If lead to spark amp is earthed then there is a spark.
Probably need cleaning as there is a gap.. . anyway thats tkmorrows task.

Hmm battery seems to have kept enough charge a was able to turn engine over briskly after being left a few days.
Points needed a clean with wet n dry to get a spark, weird i thought they were carbon so would not oxidise, seemingly not.
