Optimate 4. It works, it won't over-charge the battery, it will desulphate and restore an excessively discharged battery, and it won't run a current at all if you get the polarity wrong on your connection, which is useful if an idiot installed the pigtail or if you use clips straight on the battery post.

But hopefully it was just faulty.

I've just started working on this spreadsheet, but it should list quite a few of the more popular battery chargers/maintainers on the market. As I get the time I'll add more. Let me know if there's any mistakes - the little buggers do tend to creep in...

If they do they're hiding that fact pretty well in their documentation.

Nope. They have a five year manufacturers warranty, look in the P&A catalog. This is for the 750 ma model. The weather resistant models have 2 & 3 year warranties. I know because my last one started to overheat just after 4 years. I returned it to the dealer and was given a brand new one. But I do agree it's better to save the money and get the manufacturers one. WalMart has them sometimes a little cheaper.
