Lead Acid vs. AGM Batteries
Lead Acid Vs AGM Batteries
Understanding the similarities and differences of Lead Acid vs. AGM batteries and which one is the best for your golf cart needs.
Lead-acid batteries and AGM batteries are both made with lead plates and electrolyte, but their design and performance differ. AGM batteries are generally more durable and better performing than lead-acid batteries.
Lead-acid battery | AGM battery | |
Design | Lead plates in liquid electrolyte. | Lead plates with fiberglass mats between them. |
Maintenance | Requires venting, more frequent fluid level checks and charging. Less mess. | Maintenance-free, sealed, and can be mounted in any orientation. Less corrosion and less frequent charging. |
Performance | Can perform the same job as AGM batteries at a lower cost, but won't last as long | Can handle more power, charge faster, and has a longer service life. |
Temperature tolerance | Can be less tolerant of extreme temperatures | Can handle extreme temperatures better |
Vibration tolerance | Can be more susceptible to damage from vibration | More resistant to damage from vibration |
AGM batteries are often used in marine applications, boats, RVs, and vehicles with high energy demands. They can also be used as deep cycle batteries to power electronics like backup cameras and Bluetooth connections.
AGM batteries may require more sophisticated charging control to prevent overcharging vs standard lead acid batteries. This requires charger reprogramming or upgrade.
