I own two of these. The newer one I got is built a little different and is glitchy vs my older one. I wouldn't buy this again. Go with quality NOCO. I also have other brand of chargers. Battery tender (the bigger one), Aukey, and craftsman?) They are all glitchy. A couple has overcharged my car battery. The old black and decker one is still solid. But the best is NOCO hands down, one of the best!

I love how people give thumbs down for honest feedback. Just because it's not a raving review lol

My 2 cents, take it or leave it. Just contributing to SD, or I could not post.

No free ship to store kills it.

I'm not sure if this deal includes the spring loaded clips that grab onto the terminals of a 12V gel battery. Can anyone please confirm?
Per description " . It comes with two different connector sets, including battery clips and battery terminal rings. "

Thanks, missed the bit about the clips, was focused on the lugs.

Which noco do you have? I have the g3500 one and it's super slow. When I measured the current, it was only about 700mA.
I have the 10 amp version. Charges pretty darn quick!

It will not work if your battery is complete drain. I think most trickle/slow charger requires a min of 2v from your battery to start charging. You can always connect the dead one to a good one just so the charger can get started and disconnect from the good battery once it starts charging. This particular charger would take like 3 days to fully charge an empty battery to full.

If there is an early comment that speaks negatively about the product or could affect the sales (commissions), you'll often find a magical number of negative votes to try and kill it before it can hurt sales.

Think long and hard, have you ever seen a staff member say anything negative about posted products?

It's too bad, this used to be a great place for information and discussion, but now it's all promotional feedback with fake accounts and comments.

I have this and it came with the alligator clips that can be attached to the battery terminals.
