12 V 6 A charger for multiple battery types

The No Sew SWT3650 is a 12 V 6 A automatic battery charger and maintainer designed for lead-acid AGM gel and LiFePO4 batteries. It suits cars motorcycles boats ATVs UTVs golf carts and lawn mowers. A built-in digital display shows real-time voltage current charging percentage and status codes such as CHG ERR and FUL.

Suitable for 12 V vehicle and leisure batteries

This unit serves owners who need both charging and long-term maintenance for 12 V batteries in seasonal or daily-use vehicles. It is not for users who require floating charge on AGM batteries or who need to charge lithium chemistries other than LiFePO4. Buyers wanting higher amperage or multi-voltage capability should look elsewhere.

Pulse repair for sulfated lead-acid batteries

The charger includes an intelligent pulse repair function that targets mildly sulfated lead-acid cells to restore capacity and extend service life. This repair mode is strictly not for lithium batteries. Safety protections cover reverse connection short circuit over-temperature and over-current with spark-free operation.
