My Sears battery charger appears to have croaked after only three and a half decades, so it's time for a replacement.

I'm thinking I'd like to get a bigger one that can charge a flat car battery fairly quickly, but I realize I know next to nothing about these things, so I'd appreciate any and all info about brands and features to look for.

I have a couple of battery chargers bought from Wal-Mart for under $50.00/each. Both work well. Output is about 10 amps, and both have a "boost/start" function that will crank an engine even though the battery is pretty well dead. Dunno if I'd use that on a car with a computer, though, best to simply charge the battery, and not too fast, either. Both have meters so you can see what's happening with the charge rate, also both have a "charge complete" light.

I presume that your available variety of chargers is larger than ours Frank.
this is the item that I use(borrow) for my charging requirements--Brilliant! but expensive NZ $290 retail IIRC. Then again, batteries are expensive here also. 12v 9 plate= NZ$125 for a reasonable item

Almost all battery chargers are made by the same company, Century. The same company that makes a lot of the cheapo mig welders and plasma cutters.

So pretty much they are all the same.

I've had the good luck with Associated brand chargers:

Is Shumacher still around? They used to make some damn good charges. I've got one I pulled out of a landfill (going on 30 years old) and repaired it. Just had a bad connection in the transformer. Its a great charger but it doesn't have an automatic shut off feature, just a timer. It has a 6 volt charger setting, 12 volt maintainer, 12 volt 10 amp, 12 volt 40 amp and 12 volt 200 amp jump setting. awsome.

edit: My dad has two more of these things. They are not nearly as big, they only have a 2 amp and 10 amp rate, but one of them is going on 45 years and still works great.

Yep, Shumacher is still in business just bought a new one last year that has a 250 amp boost/start setting. The big one is great for the trucks or to get something started but I still keep several automatic smart chargers around too. Sometimes the big one is to much for a small 12 volt battery.
