Can a battery damage the car (antigravity 60ah)?

For 3 months was working great.

All of a sudden not charging. This past Monday. Had car towed to the dealer as it was not charging the battery at all.

Dealership wants to point the finger at the battery - making the alternator not able to charge it.....

I am just dumbfounded by this logic. Had been fine for 3m. Lithium specific CTEK charger charges the battery just fine x 2 (smart charger for LI batteries...no issue with the battery).

The Anti Gravity app (I have the bluetooth module) reports overcharging of the batter 1 in 5 starts and 4 in 5 no charging at all when the car is running. The same happened when I attached the original battery to the terminal via jumpers in the garage as a test....

I am thinking battery voltage module or alternator....


thanks all

 

Ive used lithium batteries with motorcycles, and never had a problem with an alternator, magneto or dynamo ( in excess of 30,000 miles ).
My 47 year old ducati for example has been very reliable with a lithium battery.


Just fit a new alternator , Jaaag mechanics always blame anything going wrong with the car as being " non OEM parts "

 

Beautiful bike F-Type dickie.

 

Confirmations very welcome, other ideas too.

Thanks all in advance!

As long as the Lithium battery has a BMS (internal or external), no. However, running a Lithium battery in a car "today" without a BMS can be dangerous. I'm sure that will change in the the near future.

Antigravity's typically do have BMS's, but typically you cannot have the battery go below a certain charge. If it the BMS fails, and the battery drops below a certain charge it will ruin it.

 

It was this one (antigravity H7).

BMS built in.

 

Overcharging or undercharging a LiFePO4 battery will kill it. Fortunately they don't catch fire like a LiPO.

Does the restart function of the battery still work or have you not had to use it? If it doesn't work its probably the BMS.

If the function does work I'm betting the alternator failed or the belt is slipping badly.

 

Guys.

I do care about the battery. And I do hope the Jaguar car stuff did not hurt my battery for sure. It may have damaged it. Sure.


The key issue for now is this: the battery is not being charged at all. The app says it is seeing no charge when the car is running.

The ctek charger can and did charge the batter just fine to 100%. Done a few times. Driving the car would leave me stranded as when running it was repeatedly losing 1-2% charger every few minutes.....it was at 80% after about 20 minutes or so....the dealer was 50ish miles away and the local beltway is crazy busy so possibly a 90 minute drive if unlucky even midday. The dealer mechanic "preliminary" idea/ thinks the batter somehow hurt the car preventing the charging from happening. That makes no sense to me.....and I could repeat this with the AGM. It also saw no charging via jumpers when I disconnected the Li batter and clamped things to the agm sitting next to the car so that the car thought the AGM was the only battery there. No charging.

 

Could be a dodgy earth connection somewhere? Back when I had a company car it used to run out of electricity 4 days after a service, which I eventually tracked down to an earth wire being connected to the alternator adjuster bracket. When the bolt was tightened, it snapped the earth cable which the mechanic didn't notice.- great piece of design.

 

Thanks. Hope that is it....again, not the battery's fault....

 

Probably not the earth issue (ground). I do love that story though. It is really cool.

-> Car holds charge if sitting still. It loses charge when running and the app reports that the car is not charging the battery when the car is running.

I have had my Antigravity H8/Group-49 Lithium Car Battery 80 amp hr. installed for 2 months now. After Jaguar fixed the parasitic load problem with a software up date the battery doesn't drain down while the car is sitting/shut off however I have encountered the problem of the car not charging constantly or regularly to compensate for vehicle loads. [I also installed their bluetooth battery tracker to help monitor things]...The result has been that the Antigravity battery didn't get charged enough and the BMS shut everything down requiring using the Restart function to start the car. My recollection is that occured when the voltage went below 11.6. Now after recharging the battery back up to 100% 13.51 volts the process of infrequent charging continues to occur and the battery is back down to 12.9 volts and still going down because charging is sporadic and short as registered on the tracker. I have recently come upon the fact that constant charging to 13.5+ volts occurs if either door or the trunk is open, go figure??? Waiting to see if the BMS Module Self Calibration goes into its second phase as described in the service manual... My dealer is concerned that the car is not set up for Lithium Batteries but I assured him that having a nominal voltage of 12.8 compares well to the stock battery.

 

Assuming nothing in the Jag has failed, you don't have any control over how the Jaguar charges and discharges the battery, so you have to work with what you have. I recommend installing an OEM style battery and just enjoy the car. What was the reason to go with this type battery in the first place?

 

Yep...went back to AGM and no issues.

Weight savings was the reason.

 

did you say you have a ctek battery monitor? If so, could you check your battery’s temp while driving? Wondering if it’s reaching unsafe levels and the BMS is keeping it from charging.

The antigravity battery should be about to operate in the 160f/70c range.
