About this item

  • Stay Charged: Provides a full charge to your vehicle’s battery before switching to float mode to maintain proper voltage levels for safe, long-term storage without overcharging
  • Extend Battery Life: Compatible with all 8V lead-acid, flooded, AGM, and gel cell batteries. Complete 4-step charging program (Initialization, Bulk Charge, Float Mode) allows for optimization of battery power. Smarter than a trickle charger
  • Includes: 8V, 1.25 AMP battery charger, ring terminal and alligator clip combo cable, 5-year warranty, instruction manual, and lifetime customer support
  • Simple & Safe: Low maintenance, easy-to-use, universal battery charger is just 4.4 x 2.2 x 2.9 inches, 0.7 lb (charger only). Spark-proof circuitry ensures no-spark connections, and automatic reversed hook-up detection verifies correct connection
  • Monitor Power Levels: Solid-state two-color 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. It is ETL US/CSA, FCC, ICES, BC, certified.

Customers say

Customers find the battery charger effective at maintaining charge throughout storage periods and works well with 8V cart batteries. Customers find it easy to install, with one customer successfully installing it on a 2000 Suzuki Katana 600, and consider it good value for money.

Battery charger and maintainer

Martin Wilson—December 20, 2025✓ Verified purchase

Love this item. It is small and handy, stores easily when not in use, made by a reputable manufacturer, and fully automatic so it doesn't over charge the battery. Battery life is better if it isn't allowed to go dead or get overcharged. Read more

Looking for a tinder, this one is the best.

Should have bought several of these. Just plug it in, no more box to trip over. Read more

Working so far. Good for the money.

Patty Ann—May 22, 2019✓ Verified purchase

I like that I can plug it in and leave it without worrying about over-charging. I would give it 5 stars if it displayed the present voltage, rather than "charging" or "fully charged". Even 1 light for each volt would be ok. As is, I cannot tell if I am gaining voltage or if the battery will never fully charge. I need to disconnect the charger and connect a VOM to estimate charging progress. Read more

Must have!

Saved my 75 year old tractor

William T Winebrunner—December 31, 2024✓ Verified purchase

I have a 12 volt version that keeps my 36 year old Corvette ready to roll when I want a relaxing fun ride. I expect this 8 volt version to keep my 75 and 71 year old farm tractors at the ready when ever needed. Read more
