The type of charger you are using more accurately determines this, but generally, your battery charger is safe to leave powered up and connected to your battery until the battery has reached a full charge. However, most chargers aren’t designed to leave your battery connected indefinitely. The only chargers recommended for extended or storage applications are the 1.5-, 2-, and 3-amp charger/maintainers specifically designed for long-term, slow-trickle charging/maintenance applications. However, problems with the battery, electrical problems in the vehicle, improper connections, or other unanticipated conditions could cause excessive voltage draws. As such, occasionally monitoring the battery and the charging process is recommended.

Standard wet cell batteries are still a common lead-acid battery type in use today. They usually are not sealed, and electrolyte can be added through holes in the top casing of the battery. Gel cell batteries are sealed and cannot be re-filled with electrolyte; therefore, they have a smooth top with no access holes. AGM (Absorbed Glass Mat) batteries are becoming very popular in the evolution of lead-acid batteries. They are sealed like gel cell batteries but are typically smaller and can be recognized by their more compact size. Lithium batteries are the smallest size vehicle battery and are also drastically lighter than standard, AGM, or gel batteries. Lithium batteries, or more typically LiFePO4 (Lithium Iron Phosphate) batteries, are lithium-ion based and offer good safety characteristics along with resistance to vibration.
