Common questions about the Long LG50-12
What voltage and amp-hours does this model have?
It is a 12V battery with a capacity of 50Ah. In banks of several units, connect only identical batteries bought at the same time.
Does the Long LG50-12 have left or right-hand polarity?
Polarity here: positive on the right-hand side. Look at the unit in your vehicle too, as reversed polarity often leaves the cables too short.
Can I use my usual charger with this battery?
Its technology is gel. The table above repeats it next to the size and ratings.
Are there other sizes in the same series?
Yes: it is part of LG Series. Other members of that family use the same technology.
Before you order: a quick checklist
- ✓ Plus pole position: positive on the right-hand side. Mixing up orientation is the most common reason a battery of the right size will not connect.
- ✓ Stored energy reserve: 50Ah. Going much lower than your current battery can leave you short on cold mornings or long stops.
- ✓ Technology to match: gel. Moving to a different chemistry may need settings changed in your system.
