Schumacher. A great product which has been around forever.
I haven't found a Schumacher charger that will charge a nearly no voltage battery (with below 5v - 6v in it) without connecting a good or 12.4+v battery to the low volt battery.
I have had the same problem. Would have to start with a dumb trickle charger then switch to the Schumacher (which picked up and did a fine job). Pain in the butt, though.
Yes that's what I also hate about the Schumacher or similar types that will not charge when a battery is deeply discharged. I wonder how many people have replaced a battery after trying to charge it and that doesn't work even on a charger for days?
If I go looking for another charger in the future it will have the
"will charge deep discharged batteries" feature.
- Suitable for charging and for charge conservation of all lead starter batteries
- Test function for starting capability and generator function
-
Charging of deep-discharged batteries possible- Charging status indicated by segments on display
- 100% safety for vehicle, vehicle electronics and battery
- Compact design and easy connection
