            Comments about Deltran Battery Tender Junior:

            I've used battery chargers for years and this is the easiest most convenient charger out there for lite duty use. I keep one on my motorcycles year around so they are always ready to go. No worry about low or dead battery when you want to just get on it and go. Also keep one on my RV house battery while not in use, usually during the winter and now that I have a new ZTR lawnmower I had to get another one to put on it for the winter. With the price of M/C batteries over $100 each,RV batteries $150, the battery tender will pay for itself in just a couple of seasons, not to mention eleminating the hassel of replacing and recycling the old battery. Besides they take all of the guess work out of it. Plug it in, connect it and forget it. A fully charged battery.

              Had issues with our RV A/C thermostat acting up and found low supply voltage. Also batteries would drain when parked/living in RV for extended period. I have used this for a couple of weeks in conjunction with coach converter and it seems to be doing the job. I do not think it would bring a completely dead battery up but that is not why I bought it.

                      A:

                      This part Deltran Battery Tender Junior, Part No. 021-0123 is completely automatic and may be left connected to both AC power and to the battery that it is charging for long periods of time. However, it is prudent to periodically check both the battery and the charger for normal operation during these extended charging periods. This part automatically switches to float / maintenance voltage after fully charging the battery. It is spark proof and reverse polarity protected.
