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.
only had it for a month but its been working fine ever since i bought it
I use these tenders for motorcycles, lawnmowers, boat batteries and my truck that never gets driven. I’ve used them for a couple years and seem to get a couple more every year... I really like the idle feature when batteries are fully charged. Cold mornings they will be on charge and when I get home from work they are back on idle.
My 3rd unit ; all work extremely well over the past years.
Great product! I have one for every car and my battery start generator. Well done product.
I am very satisfied with this product, keeps battery charged up without problems.
I have ordered several items from this company. Their delivery is very fast and their items are as advertised with competitive pricing.
Charges the battery in about 1/2 hr or less. Comes with either alligator clips or terminal ring ends.
