3/7/2014 build date. DD. Use the CTEK occasionally and it does bring back the *** but otherwise everything is good at 35k miles.So... a lot of "I replaced"... what about the "I haven't replaced"? I'm even in NE! My '13 Boxster is still, I gather, on the original battery (I'd have to quadruple check records, it has gotten through a 40k mile service when I bought it)... I do CTEK charge it during winter months where I drive it only a bit (say once every ten days for a day or two).
edit: every single time it just starts right up!
Thanks for that. Very cool about the OEM fit. Also that remote sounds awesome.FYI - I did email AntiGravity and got the following prompt and informative reply, so I'm sharing here. Link to the new model below, supposedly coming out in March.
Hello Tim and thank you for reaching out to us. We actually have a new line coming out that will be a better option for you as we've expanded the automotive segment and will now offer drop in OEM sizing so you'll no longer need an additional bracket for the battery. Outside of that, the Re-Start feature had been updated and improved to allow for a deeper discharge and the batteries will also have different capacity options to cater to the application it will be used in. Lastly, these new models will also come with a wireless remote keyfob to trigger the Re-Start function without having to actually access the battery. We are in the process of currently releasing this line and should be looking to have it available within a month or so.
Oh wow I didn't realize there was stop start functionality in Euro spec 981s! I thought it only recently got added to the 718 GT4/Spyders!I have a Cayman 981 here in the UK, I hate stop/start so disconnected the sensor attached to the negative clamp on the starter battery, that gets rid of stop/start and smart charging, the alternator now reverts to a standard charging regime at around 14.2 volts continuous same as it did pre stop/start. With the sensor not in play there is no need to code the battery and without stop/start no need for an AGM battery.
Two of the links below relate to motor homes but also cover AGM battery technology and it`s short comings.
AGM In The Automotive World.
Audi, VW, Seat and Skoda are ditching AGM batteries from their cars and are moving back to Lead acid Wet/Flooded technology that are also lower cost than AGM.
Allegedly BMW are preparing to do the same. Some BMW Dealers have been replacing failed AGM batteries with a Wet Acid technology version, Enhanced Flooded Batteries (EFB), for some years to very good effect.
