You send this to EverStart, Their customer service could not answer my question as to if it was ok to leave their BC3E maintainer on for long periods of time

“A lot of people aren’t sure what makes a battery maintainer — which is also called a battery maintainer — ”

Oh, good to know.

In reply to Demetrios Christopher. We have a 2008 335i BMW. Battery was several years old and car isn’t driven much. The clock & radio started losing settings so I started using a Trickle Maintainer for about a year now. Finally replaced the battery yesterday. No issues with resetting the computer. Thanks.

In reply to Ann Barberini. Usually, a parasitic draw can be located by connecting an ammeter to the battery, then removing one fuse at a time to see if the draw stops when a certain fuse is pulled. Any auto/electric shop can trouble-shoot your problem.

In reply to T Nelson. Hi. There are many battery maintainers that would fit this situation such as the Schumacher brand, which can be readily found at most automotive and online retailers. Hope that helps!

I do maintenance for a local fire department. they have a vehicle that has modems and computers along with flash light battery chargers that require staying powered up all the time. they equal almost 2 amps of draw. I have tried a battery maintainer that will charge at 5amps then float. Once the battery drops back down the maintainer will not start charging again it times out. Do you have a recommendation for at tender that will work in this application. Thank you.

In reply to Ms. Avril Haynes. Check to see if the vehicle has a fuse labeled as “IOD” or ignition-off draw. If you store the vehicle without pulling this fuse, it will drain the battery. Today’s vehicles typically draw power from the battery constantly, for computers, entertainment systems, all those bells’n’whistles. This relies on the vehicle being started and driven regularly so the battery can keep up with the demand. When stored, the battery is fairly quickly depleted. This may help but batteries are physical mechanical things and need maintenance, replacement, and often just die if not properly maintained.

In reply to 99Hawk (@blackhawk8001).

If you do that to many cars (especially Audis), expect an expensive trip to the dealership to recode some of the components in your car. Ironically, that list includes the battery itself! 🙂 It’s important to connect a memory saver when disconnecting the battery from an Audi (even for necessary car repairs).

When replacing batteries on cars like Audis and BMWs (which have “intelligent battery management”), it’s important to use fully-charged batteries (trickle-charge them with a battery maintainer until at 100%), then swap the batteries out while using a memory saver to prevent your electronics from forgetting important information (and I’m not talking about radio presets!). I don’t know why Audi made it so complicated but it’s all necessary.
