My GOD When will they stop making Die Hard movies?

I can't even tell what the PLOT of this one's supposed to be!

I have my doubts about this charger.

First, it says it "automatically" decides whether you're charging a 6 volt or 12 volt battery. So... if my 12 volt battery is badly discharged, and putting out 5.5 volts, will this charger "decide" that it's a 6 volt battery, and just charge it to 6 volts? I don't like the sounds of this "automatic" feature, and the product description doesn't give any further details.

Also, does this charger have a de-sulfation feature? Sulfation is the cause of most lead-acid battery failure. Sulfates build up on the battery plates, increasing internal resistance and limiting the amount of current the battery can put out. The best chargers have a high-frequency pulse mode which actually removes the sulfate particles from the battery plates, restoring current capacity and extending battery life. The literature doesn't mention this feature for this charger, so I assume it does not have it.

I would not buy this, or any charger without de-sulfation mode.

@crowbite: If your 12 volt battery is down to 5.5 volts, it most likely has permanently damaged cells and you won't be re-charging it at all. A fully discharged 12 volt battery would still have around 11.5 volts with zero load on it.

Not a farewell, just a forced redirect.

It's true, Local.Woot is no longer, but please don't despair.

Never-ending savings are still to be found on Deals.Woot each and every day, so come on in. Don't think of it as a time for tears. Think of it as a way to bring us all closer together under one roof.

Sorry

This is only for people who have bought woots

We restrict voting to users who have purchased something from one of the other Woot stores. It's not just because we want your money (which we do) - it's the best way to be sure all the votes are coming from real people and not spam-bots or phony accounts. The best way we can think of, anyway. For now.

You can always get voting rights by buying something from one of Woot's other sites:

Purchases through Deals.Woot don't count, because in that case you're not buying anything from us. And we don't have your account information for those purchases.

If you think you've bought something from Woot before and still can't vote, make sure you're logged in with the same account you used to buy from us.

Geez, why so negative?

You have to vote up more before you can vote down.

Don't get us wrong. Negativity has its place. And downvotes are just as essential as upvotes when it comes to making Deals.Woot a useful place to find deals.

But when your votes lean so heavily toward the dark side, we have to wonder. Go vote up a few things. Accentuate the positive for a little while. It'll do you some good, and it'll do the site some good, too. Then you can get back to dealing out the smackdowns, OK?

Too late, we all heard you!

Hmm... you're wanting to take your vote back?

Well, that's a bit tricky. See, we do a lot of stuff with your vote, using it to work out the popularity of what you voted for, compare that to all the other things voted on, tally up our leaderboard, work out your reputation. Someday we'll do a little cartoon showing just how hard your vote is working.

Anyway, taking votes back messes all that up, so we give you five minutes, in case you just mis-clicked. After that we've got to say no take-backs. Luckily, votes are free, so feel free to throw them around left and right wherever you see fit.
