About this item

  • Stay Charged: Battery Tender battery chargers and maintainers provide a full charge to your powersport vehicle’s battery before switching to float mode to maintain proper voltage levels for safe, long-term storage
  • Extend Battery Life: Compatible with all 12V lead-acid, flooded, AGM, and gel cell batteries. Complete 4-step charging program (Initialization, Bulk Charge, Absorption Mode, Float Mode) allows for optimization of battery power, without overcharging or battery damage. Smarter than a trickle charger.
  • Includes: 12V, 750mA battery charger and battery maintainer with 12-foot output cord, fused-ring terminal harness for hard-to-reach batteries and alligator clip accessory cables, 5-year warranty, and lifetime customer support
  • Simple & Safe: Low maintenance, easy-to-use, universal battery charger is just 3.3 x 1.3 x 2.4 inches, 1 lb (charger only). Spark-proof circuitry ensures no-spark connections, and automatic reversed hook-up detection verifies correct connection
  • Monitor Power Levels: Two-color charge status LED light indicates the state of the charge and if the battery voltage drops too far under load, adaptive charging will resume full charger output power. Automatic charge cycle functionality switches to float mode after fully charging the battery

Perfect for my motorcycle, high quality tender

KolbyJanuary 1, 2026

I have had this tender for over 2 years now and of course it works great. The brand is great, it keeps my motorcycle battery alive during the cold season. Easy to use and great value. Read more

Quality Product as Always

Don E.December 18, 2025

Have used several of their “tenders” over the years. Always work great and last forever. I use this one to keep our backup generators charged. Also use them on truck batteries for a truck that get’s drove about once a month. Read more

Reliable and Easy to Use – A Must-Have for Motorcycle Owners!

JimAugust 24, 2025

I’ve been using the Battery Tender for my motorcycle, and it has been an absolute game changer. It’s super easy to hook up, and the compact design doesn’t take up any space in the garage. What I really like is that it automatically keeps the battery charged without overcharging it. Just plug it in, and it does all the work for you. My bike starts right up every time, even after sitting for weeks, thanks to this maintainer. The indicator lights make it simple to know when the battery is charging or fully maintained, which gives me peace of mind. If you ride seasonally or don’t get out on the road every day, this is the best investment you can make for your motorcycle. The Battery Tender saves time, money, and the headache of dealing with a dead battery. Highly recommend it to every rider! Read more

Great tender

Christine M GlubkaNovember 8, 2025

We have several of these battery tenders. They work great. Our only complaint is that the cord on the newer models is much shorter than the older models. Read more

Long lasting, faithful, and easy to use.

Disastified and frustratedJanuary 4, 2026

I have had an older model for over 15 years on my ATV and am still using the original battery that came with the ATV and which should only have lasted about 4 years. The tender finally quit and so I got a replacement. Wonderful product. Read more

Saves on battery replacement

Jack C.December 15, 2025

I've been using this battery tender on motorcycles for years. Still working for more than 15 years. Saves on cost of battery replacement. Got another for a new zero turn mower. Works like a charm. Read more
