Review: It works. REALLY! - I had a battery for 2 years untouched laying in one of my cars. Tried 2 other chargers. They wouldn't charge it. Tried the optimate 6 . It worked on that battery for over 72 hours. the battery worked on the car starting it 5 times. I left the battery and car untouched for 5 days. I tried to start the car on day 6 and it started right up. If I didn't see it for myself i wouldn't have believed it. I am amazed. I'm 78 years old and play with old cars all the time. I'm sold on this charger. It's going to save me a lot of money. HAPPY, HAPPY<HAPPY!

Good product, does what is mentioned in the description

### ⭐⭐⭐ Does not work through the DIN port on my BMW C400GT
*by S***T on June 11, 2025*

The item seems to work fine, with one exception. My BMW has a DIN port that is electronically controlled to shut off when the bike turns off, with one exception. If the DIN port detects power coming IN to it, it will stay on nd the bike turns off the electronic display and running lights. With an old school charger, this works as designed. With this charger, the DIN port gets shut off as though the charger is not sending power. It may be in a diagnosis mode and therefore not sending power.
