A retrofit for gen 1 headlight (Not a gen 2 swap) (Page 10/10) buddycraigg SEP 28, 11:53 PM were you going to post the popcorn eating moving picture thingie? theogre SEP 29, 11:33 AM quote Originally posted by Dukesterpro: Yes, the battery voltage will dip below 12v from a fully charged battery in less than 16 days of no running. Similar to the OEM module. However, it becomes a moot point since this has no effect on daily driven cars like mine. Plus if you are planning on parking for a while you can simply throw the master switch on my module to disconnect the 12 to 5v power supply for the MC. Leaving you with no parasitic draw. Or if you hook it up to a battery tender, it also becomes a moot point. I would like to find a better option for reducing the draw. But it does seem to do the trick for now. Leech problem drain in 14-16 days in Good Weather may not care... In Winter & see < 32 or 0°F or Summer > 95°F, Battery @ 12V isn't only problem. Winter w/ battery even Half Charge can allow Battery to Freeze. Even if doesn't freeze, engine & more are cold w/ make it harder to start + battery makes Less Power when cold & why CA @ 32°F vs CCA @ 0°F spec's matters. Summer makes it harder to start just because of Higher Starter Circuit Resistance. Fractions of Ω adding to the circuit can matter when battery is dumping 120-150 amps to the starter Motors & Solenoid that pulls the Bendix in. (Solenoid alone draws ~ 30 amps & have a lot more wiring to get thru.) Because US is Huge vs Most, battery companies often sells Starter Batteries for "southern" & "northern" states because make charges for average temps year round. May look Identical to most but minor Grid design & other "mods" make battery last longer in the Regions to sell. So Southern battery can take heat better while Northern battery take Cold better. So Even on "Daily drive cars" W/ new batteries & full charge will often Won't Start in Winter parked over night or a weekend & weather drops below 0°. I had a small charger or battery heater to keep the battery warm @ full change when Weather Report calls for minus 10° or more.
