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.
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.
Relatively inexpensive compare to other sources. Use it on cars not driven much and all my lake batteries. I have 5 of them.
my golf cart used for farming and portable back up generator need a battery kept at full charge. this charger seems to do the job well
works great did not really need the extention but will come in handy I am sure . This does my tractor and my classic corvette . I just alternate every few days
