## Questions & Answers

**Q: It costs 3 times the original agm. does it last 3 times longer?**
A: 3 times longer is reasonable.  At the same time it also weighs about 1/3 of the AGM and provides better overall performance in terms of voltage sag during loads (in other words it doesn’t sag voltage the way AGM does).   It is much easier to install and work with being lighter weight and with the handle.

**Q: Has this been tested in extreme cold temperatures?**
A: Yep, to automotive grade cycled in thermotron chamber

**Q: Have you seen an improvement in phantom drain overnight when parked (ie, less range loss with this battery)?**
A: No I have not seen any effect on the phantom drain. However so far I’m very happy with the battery. It was easy to install, it’s significantly lighter than the old lead acid battery and with a 4 year warranty I have to assume it should last at least that long, most likely longer.

**Q: How is the battery connected to the car? 
Will it work with a Model Y?**
A: We have a battery for Model Y, this isn’t it, this one is for the Model S...  go to our website to find Model Y battery.  Thank you!

### ⭐⭐⭐⭐⭐ Second Model S, Second Lithium 12v replacement
*by J***T on April 26, 2023*

When my 2013 Model S killed its first 12v under my ownership, I just said heck with it- replace the dang thing. I did that myself. As others have pointed out, changing the 12v on a pre-facelift Tesla is a balancing act with a heavy object that would love to turn into a firecracker with contact on any of the metal it's being routed through to remove/replace. I replaced THAT PbSO4 with a Lithium that was substandard to Ohmmu. I'm stubborn, I thought "I just had a bad lead acid on that first replacement", so when I got my 2016 Model S and it killed a 12v, I replaced with another PbSO4. Poof. Gone in less than 2 years. Replaced with Ohmmu, and do NOT regret it. It can be challenging to retrofit a slightly different battery configuration, but Ohmmu made it dead simple. I'm confident that just like the last one, this will last me MANY years more than the lead acids, and either break even or possibly save some money.

### ⭐⭐⭐⭐⭐ As good as it gets.
*by A***. on July 19, 2022*

We all know that Lithium batteries of this size are "overpriced" for now, but this is as good a value that you'll find. I look forward to the day when this is priced between $200-$300. It did work perfectly in my 2017 Tesla Model S.

### ⭐⭐⭐⭐ Works - so far. Only time will tell if this is a good investment over the OEM Lead Acid battery
*by M***Y on June 7, 2021*

Hauling the lead acid battery out of the frunk of the 2013 (out of warranty) Model S was a bit of a challenge. But check out the Ohmmu videos on YouTube as they are very helpful. But remember to isolate the high voltage battery by pulling the 1st responder disconnect, Gruber Motors has a very useful video on how to do this on YouTube. Failure to do so and you will be working with power from the DC to DC converter and risk damaging it.The Ohmmu battery is a lot easier to maneuver as it is slightly smaller than the OEM battery and a heck of a lot lighter.
