TRICKLE CHARGER FOR WINTER STORAGE?

[Esmallstii]

Need a GOOD Battery tender / trickle charger for my 135. Started salting the roads here in upstate NY, and time to put my baby away for a long witers nap.
Any suggestions?

Just head into your favourite auto parts store. They are all made in China now anyway. Get one with a 2 amp setting. Leave it on overnight every week or so.

If you want a good charger, you can get one of the Deutronic units we use at work. They're only a grand.:biggrin:

You can send it here to CA and I'll take care of it over the winter for you.:biggrin:

Here in Australia I use 4 of these Jaycar Electronics devices on my classic cars that are laid up for months on end. I also use one on a BobCat that I only use sometimes months in between.

I can hop into any of these vehicles even after 6 months and the battery will be just as if the vehicle was started yesterday. Cannot recommend this style of device enough.

They don't overcharge therefore destroying the battery...


12V 5-Stage Car & Motorbike Maintenance Charger (0.8A / 3.8A, IP65 rated)


This 5-stage fully automatic switchmode battery maintenance charger is the perfect companion for any car or motorbike enthusiast.

Three different modes of operation make this charger suitable for all types of sealed lead acid (SLA) batteries - wet cell, gel cell, and AGM (absorbed glass mat) batteries ranging in capacity from 1.2Ah to 120Ah.
The micro-computer controlled circuitry will diagnose the battery's state of charge, provide the correct charging mode, eventually switching over to float/maintenance charge to keep the battery at full charge and eliminate battery sulphation. This charger can also recover slightly sulphated batteries as low as 7.5V, and will even charge batteries in sub-zero temperatures.
The interchangeable lead sets allows a charging lead to be permanently attached to your battery for quick connection/disconnection of the charger - a must have for motorbikes with hard to reach battery terminals or that classic car that spends most its life in the garage!
100% safe to leave connected to your vehicle's battery for months on end, with no damage to your vehicle or battery.

BMW recommends their Battery Maintainer, about $70.

+1 for the battery tender

make sure the battery tender (or similar) has the alligator clip connectors. the older BMW tenders used the cigarette lighter. Starting with the E90, the aux power ports (as they are now called) are no longer hot when the car is off. You will need to connect the tender to the posts under the hood.

Thanks for all the info Guys.
Dan @ united actually PM'd me and they have one for $51.75.
I'll prob go that route.
The Jaycar unit looks real nice too though. I like the disconnects on it.
