Powering on Together! Sale for 911 GT3, GT3RS and 991R owners
Hey everyone,
In light of the many challenges being faced, Antigravity Batteries is offering some large discounts on our products in hopes that it may offer some form of relief and assist in reopening the economy.
Question for the OP. Curious how long these batteries are 'good' to just sit in a corner in the garage? I have a '15 M4 which came stock with a Li ion battery, so it is now 6 yrs old and a '16 991 GTS which has the original AGM Porsche battery, now 5 yrs old. I have been debating whether to get an antigravity battery as a 'spare' should one of them fail. Both test fine currently. They may go another 1 yr or 3 yrs. Who knows.... Would the same replacement Li battery work for either car and what model would this be? I would want the best available. Thanks for your help.
Ah! Missed it too. Great product I sent the link to my Dad anyway he needs one of your batteries.
Morning everyone, as Rennlist members you guys can ALWAYS email me directly and we'll be sure to get you take care of.
Best regards,
Chad chad@antigravitybatteries.com

As long as it's not connected to anything you should easily be able to let it go 6-8 months or so as lithium has an very slow self discharge rate in comparison to lead/acid compositions. Of course it would always be best to check it every few to confirm good voltage but you shouldn't have any issues there. I would think the H6 should be good for both but I'd want to double check the measurements on the M4 just to be sure as I'm not seeing specific group sizing on their lithium model.

Email sent! Similar question. How long will the stock battery last once it’s removed? Not that I would need it. Just curious as to what people do with their stock battery once they install a lithium one. I’d like to keep if for instance I sell the car I would put everything back to factory. Thx
