Re: Battery charger voltageI have a Schumacker 6 or 12 volt 2/15/125 amp charger it probably over 20 years old. I do not know what type it is. With out it being connected the battery it reading 10.5. The battery went up to 12.6 ok. So I guess it working ok. What type of charger should i get for normal charging of a regular lead adic battery? Thanks |

I have a Schumacker 12 volt with switch for conventional batteries and low/no maintenance/deep cycle. It is a 10 amp model and is automatic.
Just now: Checking the output voltage on the charger, am getting 10.7 volts on either setting. The reading is steady. Of course the amp meter on the unit is at 0 amps. Do not have a discharged or other battery to hook it to and then check voltage dc.
Have used this unit on deep cycle, low maint., convential in all kinds of conditions. Used on Tractors, Bobcat, ATV, Trucks, old vehicles, new vehicles, deep cycle batteries from those scooters people ride on [got those free from neighbor and used them for portable 12v lights].
The Auto feature works great, have forgot that battery hooked up and had it connected for a week or so, more than once with no damage. Did that a couple of times to one of the Bobcats, especially in winter at freezing temps. The battery in it gets a good workout with many start/run/shutoff cycles per day. When I sold it, it had the original battery and it was 7 years old.
It is probably around 25 years old and made in US.

If the battery was reading about 10V, it could have a shorted cell (a fairly common issue). If it charges up to 12.6V or so, let it sit for a day or two (with the terminals disconnected). If it sags back down to the 10V range, it definitely has a bad cell.
Most Midtronics brand battery testers (if you know someone who has one) have a shorted cell detection feature- this will tell you right away, without having to wait to see what the battery voltage does over time. |

That's a dead battery. Replace it. |

Sorry the charger was reading 10.5 not the battery. But it charged the battery to 12.6 volts. I bought a new battery and ordered another charger. |

For storing lawn batteries, deep cycle, or other types when not being used, I recommend a Battery Tender. It keeps them topped up and won't overcharge. Leave it hooked up 24/7. |
