If it’s not a Deltran Battery Tender®, it’s just a pretender.™

We make chargers that fully charge a battery then automatically switch to a maintenance mode when the charge is complete!
There has been some confusion in the battery charger world that some of our chargers are simply maintainers ---- NOT TRUE! Each and every Deltran Battery Tender Battery Charger® regardless of its size is programmed with a microprocessor that will correctly charge a battery then automatically switch to a maintenance/float mode.

How it All Started

In 1989 we modeled our initial design after the tried and true battery charging algorithm used on our nuclear submarines. Many of our chargers are used to charge the Bradley Fighting Vehicles and Hummv’s in Afghanistan and Iraq.
Our devotion to providing the most advanced practical battery chargers available has never waivered! We constantly update our designs to address the new batteries as they become available to the market.
