10 amp manual battery charger

[05e83]

I am bring my car back to life after a few months of sitting.. I just bought http://www.sears.com/diehard-10-amp-manual-battery-charger/p-02871221000P" charger. What is the correct way to hook it up? The x3 manual doesn't speak of charging the battery.

Page 108 of an E83 manual, on this site in Ref Docs, shows the usual underhood poz and neg lugs. The crummy line drawing is tough to read, but it appears to be similar to my E53, with slight location difference.

I attach my Batt Tender alligator clips regularly to my underhood pos and neg lugs, with no problem.

That Sears Batt charger doesn't say much in the specs, but if it has an adjustment, I would set it for the lowest amp setting you can vs giving it a high amp 'hot shot'. Hook it up and if it takes a day or so, so what...

hi, thanks for the reply. I am aware of the posts under the hood. But the manual says nothing about charging, only jumping. I was wondering if there are any precautions about charging the batt while connected to the car.

The charger has a 10 or 2a charge rate.

The manual says nothing about 'charging' because the manuals have been dumbed down over the years, imo...Biff & Buffy don't want to know/think about having to charge a battery, etc. BMW NA is selling the 'driving experience', (preferably a leased 'experience'), and the friendly dlr will be glad to sell and install a new batt for the next set of glazed over eyes, as the batt is never covered under extended or CPO warranty.

Those lugs are made for connecting a 'jump' or a charger...

I charge our '01 E53 regularly, and often for several hours/days on my very low amp Battery Tender. Orig batt went 7 yrs, the replacement has gone 7+ yrs and is due to be R&R'd; both those batts were charged often, through the under the hood lugs.

Same for my '02 VetteVert and my 3 m'cycles.

Adjust that Sears charger down as low as it can go, (hopefully it provides for that), attach clips to poz and then neg under hood, plug in charger and give it a day or day(s), and hopefully you can resuscitate your car's battery. Easy stuff...
