What’s everyone using for trickle chargers these days? I’m barely ever leaving my house now that I’m in WFH status for the long haul.

I have a couple of these that I've used for the past few years.

I had my M5 on the same battery for 10 years. For as long as I have owned the car.
Only thing I have used was a battery tender.

I have one of the Junior models on my f10 535 and the Plus model for my M5. Money well spent as you will greatly extend the life of your battery.

CTEK MXS 10, have the comfort plug plumbed into the points under the bonnet (hood). Brilliant charger, cycles the battery when needed etc to keep it in great shape.

I may be lucky but I've never had to use a trickle charger / batt conditioner / etc. My car sits for about a month every year when we go out of town. If I was worried I'd just disconnect the battery.

Maybe trickle chargers are damaging batteries? Just thinking out loud...

CTEK 4.3

I start my car about less than once a month and drive about 500 miles on it a year. It has never failed me and sometimes i go without hooking it up for a couple of weeks.

I like it, don't know how long if my battery will last longer though because the battery is only on it's 4th year old
