12 Volt Battery Tender Plus Battery Charger (1.25 Amps)

Deltran's Battery Tender Plus is one of the most recognized battery maintainers on the market, and for good reason. If you have a motorcycle, ATV, snowmobile, classic car, or any vehicle that sits for extended periods, a dead battery is the usual welcome back. This 12-volt, 1.25-amp charger keeps the battery topped off and healthy while the vehicle is parked.

The charging process runs through four stages: initialization, bulk charge, absorption, and float. The charger automatically moves between stages based on the battery's condition, so you connect it and walk away. A built-in 72-hour safety timer prevents overcharging even if something goes wrong with the sensing circuit. It works with lead-acid, AGM, and gel batteries, covering most 12-volt applications. The output cord measures 10.5 feet, and the included 18-inch cable has both alligator clips and ring terminals so you can choose the connection method that works best for your setup.

Safety features include spark-free hookup and reverse polarity protection. At 1.25 amps, this is a maintainer first and a charger second. It will bring a partially discharged battery back, but if you need fast charging for a fully dead battery, a higher-amperage unit would be more appropriate.
