I second this. Excellent customer service. I had one go bad the day after I hooked it up. They sent a replacement out to me that same day and paid for the shipping to return the faulty unit. The new unit has been working great.

My complete refit is taking completely too long!

Don't use a trickle charger

Don't use any trickle charger. It will just cause your batteries to sulfate up and fail prematurely. Get a good three stage charger with the capacity to equalize the battery intermittently and keep it plugged in when in port. It will stretch the life of your batteries greatly. My house batteries (4 golf cart deep discharge batteries wired as 2 twelve volt banks) are over 8 years old and still going strong. I personally use the Xantrex 20 but any high quality one will do.

Going back to the original question, any trickle charger will "keep up" a battery against normal self-discharge.

"Don't use any trickle charger. It will just cause your batteries to sulfate up and fail prematurely." That's just not true. using a trickle charger to counter the normal effects of self-discharge is ALL that is necessary to prevent sulphation from normal self-discharge. Equalization and three-stage charging is all nice and good for batteries in use--but beyond the scope of simply maintaining a battery out of use for a couple of months.


HF is a good source for disposable tools, sometimes I buy them there with that purpose in mind, to do one non-critical job at a price. Only if I can take it back or throw it away without any injury or tears.

But considering how many house fires are started by "wall warts" and other little low-voltage devices...I'm not sure I'd want anything from HF plugged in long term while I slept.
