Sealed lead acid battery

Positive characteristics

• Sealed, and so much safer than standard lead acid.

• Extremely high current output - low internal resistance - extremely high conversion efficiency (gel 85-90%, AGM 95%).

• No voltage depression (“memory” effect).

• Low cost.

• Low self discharge (2-10% per month.

Negative characteristics

• Does not like deep discharging.

• Can (permanently) die suddenly.

• Cannot be fully charged.

• Heavy.

• Low storage density.

• Reduced capacity with increased temperature (50% with each 8°C).

• Reduced capacity under heavy loads (Peukert Effect), although not as bad as lead acid.

• Cannot be stored flat.
