Has anyone checked out Optimate chargers - their version 6 charger will charge/maintain/repair Li-ion batteries and a host of other types including the AGM in my BMW GS1200 motorcycle (sold on Wunderlich USA site and recommended for the Bimmer) - have not yet researched them for the M3/4 but curious if others have (my car is a DD and never stored so not an issue for me - no real winters here!).

FYI, BMW recommends to hook the charger in the designated charging points under the hood. As for leaving it permanently in either locations, i personally wouldn't feel comfortable, as the crocodile clamps could dislodge and not sure about having inactive electronics (charger) connected to the battery ... My two cents !

Actually, the CTEK lithium charger comes with a separate cord that has eyelets instead of clips. This can be permanently connected to the jump start post, amd a nearby ground with no fear of disconnecting or shorting out. This is what I did. For the record, the charger is not left connected to the car, as the short cord has a quick disconnect plug that is capped, making it weatherproof. Just pop the hood and connect when the car will sit for extended periods. |

I thought the above poster wanted to leave the whole charger inside ... BTW, i'd also feel nervous leaving short cables connected to the battery charging posts ... I'd have to really zip tie it, and weather proof it 100%, the pic attached doesn't show the cap ! |

Anyone use the NOCO Genius G3500?
http://www.amazon.com/NOCO-G3500-Ult.../dp/B004LWVEKS I can get a killer deal on it and it looks like it does 12V lithium batteries. Any thoughts? Really only need it for coding, can I just use a regular 12V 3 Amp battery charger to keep juice in the battery for an hour or so? |

BTW, you totally don't need it for coding; just get everything ready in advance. Even if you don't, you can turn on the car and it will have no power drain, and no danger of shutting off in the middle of the session. If you'll be using battery power for extended periods of time (like listening to or tuning an audio system), it's best to get an external power supply. |

Since I have an e90 335i (AGM battery) and only need this as a backup power source during my flash. The MHD flash takes about 50 minutes... I'm going with the CTEK (56-864) MUS 4.3 for $60 |

@peterparker and others, just FYI and in case if you ever plan to flash a module that takes long, better go with a PSU and not a 4.3Amps trickle charger. Some people flashed small/quick modules by ensuring battery is topped with the CTEK lithium, but I wouldn't risk it.

My car has been sitting in the garage for the past 2 months. Started right up like normal today.
Put it on the CTEK charger anyway and took about 8 hours to get to level 7. |

This just popped up in Amazon, http://tecmate.com/products/optimatelith5a/, it seems to be another good charger for our batteries. A bit more intelligent than the CTEK, albeit a big bigger and from another European company. They confirmed that this works for our cars and other LifePO4 equipped vehicles. FYI here's an interesting comparison between battery technologies.
Mine is on its way! Last edited by aboulfad; 02-17-2016 at 06:28 AM.. |
