  • Vehicle Versatility: With a full range of products, there's a Battery Tender® for every ride—from motorcycles, ATVs, and lawnmowers to cars, boats, and RVs.
  • Quick Disconnect Harnesses: Many models include a quick disconnect harness, allowing for easy, tool-free connection and disconnection. This is perfect for vehicles with hard-to-reach batteries.
  • Trusted Brand: As a brand with over 50 years of proven performance, Deltran Battery Tender® is the name customers have trusted for generations.

How to Choose the Right Battery Tender for You

Finding the perfect Battery Tender® depends on your vehicle and battery type. Use this guide to help you find the right charger for your needs:

  • For Motorcycles, ATVs, and Lawn Tractors: The Battery Tender® Junior or Battery Tender® Plus are excellent choices for their compact size and low amperage.
  • For Cars, Boats, and RVs: For larger batteries, consider a higher amperage model like the Battery Tender® 5A or a multi-bank charger for fleet applications.
  • For Lithium Batteries: It is critical to use a charger specifically designed for lithium technology. Browse our selection of Battery Tender® Lithium-compatible chargers to ensure proper charging and maximum lifespan.

Frequently Asked Questions

Q: What is the difference between a Battery Tender and a trickle charger?

A: A traditional trickle charger delivers a continuous, unregulated charge that can overcharge and damage your battery over time. A Battery Tender is a smart, fully automatic charger that stops charging once the battery is full and switches to a safe float or maintenance mode. This prevents damage and allows it to be left connected indefinitely without worry.

Q: Can I use one Battery Tender for multiple vehicles?

A: Yes, you can. A single Battery Tender can be easily moved between vehicles. For convenience, you can purchase additional quick disconnect harnesses to leave permanently on each battery, making it easy to swap the charger between them as needed.

Q: Can a Battery Tender charge a completely dead battery?

A: Yes, most Battery Tender models are capable of charging a deeply discharged battery, but it will take a long time depending on the amp rating of the charger. The primary function is to maintain a battery, but the initial charging of a low battery is a key part of its operation.

Q: Can I use a Battery Tender on a lithium battery?

A: You must use a charger specifically designed for lithium technology. While Battery Tender makes a wide range of chargers for lead acid, AGM, and Gel batteries, they also offer models that are specifically designed for safe and proper charging of lithium (LiFePO4) batteries. Always check the product details to ensure compatibility.

Q: What are the quick disconnect harnesses for?

A: Many Battery Tender models come with quick disconnect harnesses. These harnesses connect directly to your battery terminals and provide a simple plug-and-play connection point for the charger. This makes it easy to connect the charger to a battery without having to get to the terminals every time, which is especially useful for hard-to-reach batteries on motorcycles or ATVs.
