Not once did that thing fail to light up on the first turn of the key when I got back to use it.


I so agree with the above.I'm on my second Odyssey battery*, the car lives in a dry garage and I have a top of the range CTEC trickle charger connected at all times.

If I have not used the car for a while I get the dreaded 'clunk' and no spin of the starter.

I have had all the usual suspects checked - the earth, starter connections,etc.

Now ,here's the odd bit - if I attach my trusty Costco booster the car starts first time. confused2 This would lead me to think the battery has a low charge ,but how can it?

* I even purchased a proper battery tester that tells you the cranking output and all seems well.

To add insult to injury we have an ancient Toyota (which we call the 'shopping car') which is shamelessly abused.It stands out in all weathers and can be left for weeks on end with snow, rain ,the alarm on ,you name it - and it always starts first time swear

I have been looking at the new Lithium batteries lately and wondering whether these would be a sensible upgrade.....

James, Batteries, I had had a few, my most recent 6 weeks ago. I have tried a number of "fixes" such as new starter motor, Carcoon tent to prevent any moisture, new CTEK, various battery testers, all these efforts have not solved the issue. However I am on a new strategy and so far it is working well even in the depths of winter. I disconnect the battery after each run, I use a simple screw on off device and secondly I only run a CTEC for only 45 minutes a day. I am strongly suspicious of the CTEC charge rates on the Odyssey which I believe might be cooking the thin lead plates it comes with. I try to get the car out at least once a week during the winter and so far no clicking and a very strong start from the battery, here's hoping.


- interesting observations here Dave;I too am becoming a little suspicious of the CTEK charger. thinking

I don't think it is able to get the battery to the optimum voltage/amps - which is why my power pack will get the motor spinning when the car battery won't.It may well be 'cooking' the plates too;I asked various Odyssey suppliers and most said a trickle charger would be OK,but some said it wasn't needed....

I may try your strategy of getting the battery up to 'full' on the CTEK and then disconnecting and see how that goes
