igor Posted August 19, 2018 Share Posted August 19, 2018 My coon had a new battery in it when I bought it in 2013 and it's still sweet. The battery in my Civic must be at least that old too cos I bought it for my previous coon. Think I've had to charge that one once cos lots of short running / sitting unused for months. Mary's Laser on the other hand has had at least two replacement batteries since we got it in 2012 but it has a tiny battery cradle that a decent sized battery won't fit in so it's half fucked before it even begins.

Nominal Posted August 19, 2018 Share Posted August 19, 2018 It seems 5 years is about typical in my experience. Quote Link to comment Share on other sites More sharing options...

The old battery on Jane's car was only 5 years old but got to a point where it's CCA was only like 240 (repco test) and would turn the engine over quite slowly when engine was cold/ been sitting a few days and would only hold enough charge for one start so you couldn't just move the car a few metres to get another car out. After doing that the engine would still turn over but super slow. Battery must have had a bung cell or something causing high internal resistance. Threw a new battery in the other day so should be good now Check charge V with a true-RMS meter? Quote Link to comment Share on other sites More sharing options...
kyteler Posted August 20, 2018 Share Posted August 20, 2018 Warranty on batteries is typically 2-3years for regular use and 1-2 for commercial application. Life span is obviously use dependant but getting 5 is considered OK. I tried to charge a battery from works John Deere which was 6 years old but it wasn't having a bar of it. Sat at the same charge level for ages then exploded. Hah. Ah well. 2 Quote Link to comment Share on other sites More sharing options...
yetchh Posted August 20, 2018 Author Share Posted August 20, 2018 Battery in the 121 is at least 9 years.. as is the one in the zephyr 3 Quote Link to comment Share on other sites More sharing options...
Alfashark Posted August 20, 2018 Share Posted August 20, 2018 Load and cycle dependant - The battery in my Golf is good for 2 years between charges, then just whack it on the Ctek overnight and it's good to go for another 2 years. No clock, no stereo, no alarm. Only gets started to move it out of the garage if I need access to the shit stored behind it. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted August 20, 2018 Share Posted August 20, 2018 I have a caliber one (super shit auto) It does lead acid, calcium, and gel. It pulses to clean the plates, and has a maintain mode when a battery is charged. It won't charge a dead flat battery though. I had a scooter battery that had sat for years and was.dead. I hooked up those test leads from it to the charger when it was charging a known good battery. Once it was charged I unhooked the good battery and used it. But I didn't realism I'd left the charger on and left those test leads on. An unknown number of days later I saw it was still turned on. And the battery had come back from.the dead. 2 Quote Link to comment Share on other sites More sharing options...

I am still using a battery I bought 9 years ago, got it load tested late last year by the same place I bought it from, their verdict was it was still good. 1 Quote Link to comment Share on other sites More sharing options...
yetchh Posted January 25, 2019 Author Share Posted January 25, 2019 Just fried the one in the zephyr.. Left it charging on an old charger by mistake for a week.. New one says its charged but barely turns the zed over.. Doh Quote Link to comment Share on other sites More sharing options...
Hemi Posted January 25, 2019 Share Posted January 25, 2019 Been repeated heaps, but yeah dont let them go dead. most chargers now days are like 10 amp most which just wont wake a slumbring beast, they probably cut out/ cut the amps because they think it has a dead cell which if fed like that will cause boiling ( both charging and in the vehicle) The batts in the trucks here last like 2 months tops in summer if they go onto the gravel due to heat and vibration. Dont be mad if you have to replace them every 3 years tbh. couple hundy over thet term isnt that bad. 2 Quote Link to comment Share on other sites More sharing options...
oldrx Posted January 28, 2019 Share Posted January 28, 2019 Checked the batt in the project, some kind of big calcium generic thing, usually charge it about twice a year when it gets down to the low 12s V. Read 16.5!? Must check meter on daily to see if its telling lies otherwise what the heck? Quote Link to comment Share on other sites More sharing options...

I had this once and google told me its because the internal battery voltage is used as a reference, or something like that. I had that with an old 4age alternator, read 18v. Changed Alternator, same thing. Turned out to be the multimeter battery even though the low voltage wasn't indicated. 3 Quote Link to comment Share on other sites More sharing options...

I once convinced myself that the alternator was over charging and took it off the and into the auto-sparky to test for me. It was fine and as I was walking out the door he said, oh by the way check the battery in your multi-meter... Of course when I put my glasses on I could just see the low-battery indicator 2 Quote Link to comment Share on other sites More sharing options...
WLDRX2 Posted July 19, 2019 Share Posted July 19, 2019 Does anyone have the hook ups on Ctek chargers ? Looking at getting one that I can leave on to maintain the battery . Probably the Mxs-10. Quote Link to comment Share on other sites More sharing options...
