5 Amp Weather-Resistant Battery Charger is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Easy to use. Works like a charm. Due to cold weather and lack of riding my battery was struggling. Made the order, had in just a few days. (Make sure you get the US charger!). Plugged it right into the SAE adapter. Was charged and running beautifully 3 hours later!!! I love that I can leave it plugged in and it will not over charge, automatically switches to trickle (float) charge. Comes with SAE adapter, battery clips and rings. No reason not to get that battery up and running.

Rated 5 out of 5 by from 5 Amp Weather-Resistant Battery Charger Needed a good, solid charger for the bikes and the cars. I re-charged my car battery out in the (sometimes) poring rain with no problems. Then I charged my FXDB and left it on to maintain the charge. The Results: both my bike and car started right up. No hesitation. It's simple to operate. just hook it up and plug it in. If your battery needs a full charge, it goes full bore. If it needs a maintenance charge (trickle charge) the charger automatically reduces to a trickle. It will keep your battery charged for weeks without overcharging. No muss, no fuss. When you can't get out in the winter, this sure beats running your engine to build up your charge and hope said engine is not getting too hot. I highly recommend this product.

Rated 5 out of 5 by from Saved the Day! Started with a bone-head move...left the bike lights on when I parked it in the garage...discharged overnight. Next day, no luck starting up. Was not too comfortable in attempting a charge from the truck, after reading a few online forum posts. Local H-D dealer not too far away, made the purchase, and a few hours of charge later (perhaps even less was needed), I was back on the road. Going to continue using this as a battery tender, as wintertime rides are less frequent. This unit may be a bit of overkill for trickle charge, though it's here, and it saved one day already!

Rated 5 out of 5 by from Exceeds Expectations This battery charger plugs right in to my 2007 H-D Road King CVO motorcycle. The charger is high quality and works like a good charm! I am happy to report that this product exceeded my expectations and I am very pleased.

Safe to leave the charger on indefinitely?

I run this on my Ultra Limited (2014) when I'm not riding it, sometimes at a stretch beyond 2 months. Would it damage the battery? Should I get a lower amp one?
Asked by: bbbrider
Hi bbbrider-- Well, I would not leave the 5 Amp Weather-Resistant Battery Charger plugged in for long than the allot time. Usually it takes up to 2 hours for a full charge--times do vary! However, leaving a battery charger in for a longer period can prematurely "age" or limit the usage. Thanks for the question!

When using charger

The amber light stays steady for a short steady period followed by a flash repeatingly.(amber for 5 seconds then flash-repeat) Not the on off on off indication poor connection. What does that mean and if charger is bad, what or how long is the warranty?

What should I do to have the charger Operate in Europe ?

Hi I purchased the 66000041 as it says clearly that it accepts worldwide inputs voltage100 to 240 VAC @ 50 to 60 Hz . However on the back side of the charger I bought is JUST written "INPUT : 120V ~ , 1.2A 50/60 Hz" Now I need to use this charger in Europe ==> i.e 220V - MY QUESTION : What should I do in order to use this charger in Europe besides changing the USA input plug into EU input plug ? Will the 66000041 work properly if plugged to 220V ? Thx Eliaz
Asked by: Draga
Hi Draga, The main units are the same for the 100 to 240V tenders. It will for sure take up to 240VAC. The difference in the part numbers are the different plugs, which I'm sure you already know. I would highly recommend you use the correct part number with the plug made for your voltage. What I can not say for sure is if a 110V plug will be able to handle 220V. Because of this, I will have to advise against using an adapter. Thank you
