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.
Very nice compact unit.
Great product, fast shipping.
Just what I needed/wanted and came with an adapter to just plug in to charge battery w/o having to take the battery out. Bought for my 2006 portster
I needed a charger for my mat gel batteries and I didn't have to go far. This one was there for a nice price. Couldn't pass it up. It is a smart charger and works great!
It's a great little piece of equipment and is helping to make my small batteries (mower, motorcycle) last longer.
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.
