How low of a battery voltage can this charger see and charge?
Deltran's 021-0123 Battery Tender charger can sense voltages as low as 3 volts and go into the recharging mode. It has an 80 hour safety protection feature that will stop the charge if the charge time is longer than 80 hours.
If the battery has been sitting in a dead or extremely discharged state for an extended period of time, the battery may not take a charge due to sulfation built-up on the plates.
Wish I would have purchased one sooner. The unit comes with leads with clips to attach to your battery and, leads with ring connectors that attach at the battery post. I attached at battery post and ran the leads to a convenient point where the battery cover does not have to be removed for each use. Really glad these connectors came in the package. Nice clean install and battery always up on charge.
Simple, does exactly what it is designed to do. half the price of H/D. Same thing,
This used to be a nice product. Now it is barely a shadow of its former self. The transformer seems like a hollow shell. - no weight. Furthermore, two transformers cannot fit side-by-side in adjacent plugs on a standard power strip, because the transformers are too wide. California Compliance seems to have stripped the quality from this product.
Can't do better than this charger to maintain batteries that set. attach the leads, plug it in and forget it.
a great quality, brand-name, product
I am faithful to the Battery Tender products. At both my winter home and summer home I keep my cars and boat batteries plugged in for months at a time . I have proved to my self that the battery longevity is because of this.
