I leave my 430 Scuderia plugged with a battery tender. So I leave parking at full charge and when coming back battery seems much lower. See pics I wonder whether this is normal. I am worried the battery power gets too low for a perfect gearbox functionality? Happy to hear your thoughts. Image Unavailable, Please Login
Perfectly normally..heat from drive and drain will be slightly lower than a fully topped off battery .. also there is always a slight float charge that gets dissipated..even if you were to remove charger for 24 hours That all being said Check voltage at battery after having fully charged and sitting off charger for 24 hours Check voltage at battery while cranking Report back here
Get one of these: https://www.amazon.com/dp/B07NSTQCM8?psc=1&ref=ppx_yo2ov_dt_b_product_details It should be on every vehicle really that gets stored or has issues with low voltage like our cars. It's a great way to monitor battery health and keep tabs on your alternator as well.
Brian Not sure how you read the posts or what you are adding here No one is judging the car's system based on the charger OP stated that the charger "says charging" when he comes back form a ride - I replied perfectly normal to see that as I have seen that on all my cars ( different brands ) with different chargers I further said ..to make sure monitor voltage on battery terms with a multimeter (implied) to see if he has a problem with battery I will further state here he should add one more test ... also look at voltage at terminals while car is running
I was not replying to you. I never read your post. And yes, the OP was indeed judging his cars system on the charger. But thanks for your concern.
Check battery voltage with a meter. Here's the one I use: https://www.amazon.com/gp/product/B000KIMHRQ/ Google "battery voltage chart" for the type of battery you are running.. but here's one for AGM types: Ray Image Unavailable, Please Login
Perfectly normal for the Ctek chargers (which is what that is, with a Ferrari sticker on it) to report that level when you first plug it in. If you look at the manual for the charger, those first few status lights mean "yeah I can tell I'm connected to a 12V battery, give me a while to figure out how charged it is". Manual: https://www.ctek.com/storage/3B398FAECBD7C50C293A4E8883C640EE894DB98C66DAA2F32373B2ADCB02FD09/00000000000000000000000000014050/pdf/media/f9d0203cf44e43dabdbf3248f7f2cc45/MXS_5.0-manual-low-UK-EN.pdf It should move up through the status lights pretty quickly though - like less than an hour. if you're that worried get a multimeter on the battery terminals. But mine behaves like this with a brand new Bosch battery so I wouldn't give it another thought.
