911virgin Posted 13March, 2018 Report Share Posted 13March, 2018 hi all I had the car's battery checked a few weeks ago @ Porsche and they told me its @ 51 % life left? they said I should get a new battery. is this just a sales ploy or does the battery still have quite a bit of use left? I drive the car approx. once/week for 30 minutes. any help/input much appreciated cheers Link to comment Share on other sites More sharing options...
911 Snake Posted 13March, 2018 Report Share Posted 13March, 2018 How old is your battery? It's probably something to keep on your radar for your next service I'd say. I'd also #getoutanddrive ! 30mins once a week doesn't allow much alternator charging for prolonged battery life. Final step, I'd recommend you be to get a ctek trickle charger if you have a power outlet in your garage. This should keep you battery topped up whilst not in use http://store.batteryworld.com.au/CTEK-MXS-5.0-12-Volt-5-Amp-Battery-Charger Link to comment Share on other sites More sharing options...
911virgin Posted 13March, 2018 Author Report Share Posted 13March, 2018 thanks very much for the tips I got a prosche trickle charger which died after a year, hence my visit to Porsche to get a new one Link to comment Share on other sites More sharing options...
911 Snake Posted 14March, 2018 Report Share Posted 14March, 2018 No problem, I THINK the Ctek unit may be what Porsche actually uses - they just re-brand it. If you do need a new battery in the end, I'd recommend the Bosch Mega Power SM 58014. It's the biggest one that will fit in a 997 I believe Link to comment Share on other sites More sharing options...

Francois Posted 14March, 2018 Report Share Posted 14March, 2018 Varta battery are the best way to go. Battery world has tehm, and I believe you can get 10% by just asking for it. Bosch are good too. Link to comment Share on other sites More sharing options...

Zelrik911 Posted 14March, 2018 Report Share Posted 14March, 2018 Isn't there a special Porsche battery on 997's (& later) that can talk to the ECU once the computer recognises it? Supposed ups the charge if the battery needs it, I wonder what the Porsche tax & Oz Jealousy tax is on that part? Link to comment Share on other sites More sharing options...
sleazius Posted 14March, 2018 Report Share Posted 14March, 2018 I was very happy when I changed over to Varta - massive difference in crank power. Link to comment Share on other sites More sharing options...
dan_189 Posted 14March, 2018 Report Share Posted 14March, 2018 +1 on the genuine charger being a Ctek. For less money than the branded one you can get the next model up in the ctek range. Dealership told me my battery was on the way out and quoted $500+ two years ago. I kept my current battery (no pun intended) it's been working well so far but a replacement is on the horizon. I'll probably go an optima red top but you do need an adapter plate for it to fit. Link to comment Share on other sites More sharing options...
OUTATIME Posted 16March, 2018 Report Share Posted 16March, 2018 My two cents. Andy Stack Porsche Specialist mechanic at Rennsport recommended the Varta or Bosch S3+ (80amp) to me today for my 997.1S. Due to availability went with the Bosch at around $170 from Goodwill in Cockburn Central. Also comparably the Noco 7.2 charger seemed better value than the well advertised Ctek 10 given similar functionality but was $80 dollars cheaper. Apparently a good charger has about 10% of the battery amps which makes the Ctek 5 (comparable price to Noco 7.2) a little under powered. I was using the Ctec 5 this morning to charge my old battery and it took quite a while from dead to 60% with extreme heat coming from the Ctek 5 after a couple of hours. Will try the Noco 7.2 on it before putting in my new Bosch tomorrow. Link to comment Share on other sites More sharing options...
aia Posted 21March, 2018 Report Share Posted 21March, 2018 Just picked up a new Bosch battery for 997.1 3.6 Bosch 730CCA 58014, part number BOS458014 Mega Power plus $300, recommended for 997's Link to comment Share on other sites More sharing options...
OUTATIME Posted 22March, 2018 Report Share Posted 22March, 2018 Update: Ctek 5 got stuck around 60 to 70 percent. Switched to Noco 7.2 and it was near 90 percent after a couple more hours. Extra ampage definitely helped. Pretty sure Ctek has 40 percent off at repco in WA anyway so can probably get a Ctek 10 for the price of a Noco 7.2 at the moment.

911virgin Posted 17April, 2018 Author Report Share Posted 17April, 2018 if my current battery has approx. 50 % life in it (was tested @ Porsche centre last month ) do I need to change the battery now?

Daz987 Posted 18April, 2018 Report Share Posted 18April, 2018 I've noticed that when your battery is on the way out, you start to get weird electronic things happening, like windows going up and down, weird engine/car failure lights that come and go, lock/unlock will then won't work... Even the trickle charge won't fix the battery when you get to that stage. Once a week, 30 minutes not enough for these cars... Do a good drive on a weekend - 2 hours plus non-stop if you can... 997.1s love it. In fact, all 911's love that!! Link to comment Share on other sites More sharing options...

Every so often I'd unlock the car, open the door and the driver seat electrics would kick in!! (lower back bolster would start inflating) - Ctek full charge on the battery a month ago and hasn't happened since. Link to comment Share on other sites More sharing options...
