What You Pay For
- Amps: higher amps mean faster charging and usually a higher price.
- Smart features: multi-stage charging, AGM and lithium modes, and repair or desulfation modes.
- Engine start: a high-current mode for starting the car at home.
- Build and brand: weatherproof cases, longer cables and established support.
Maintainers: About $30 to $75
For a car that sits, a maintainer is the cheapest useful option. Consumer Reports notes that maintainers are meant to preserve the charge level rather than resurrect a dead battery, and that they turn on and off as needed.
- Stay Charged: The 1.25 AMP, 12V battery charger provides a full charge to your powersports battery before automatically switching to float mode to maintain proper voltage levels without overcharging the battery
- Extend Battery Life: Compatible with lead-acid, flooded, and sealed maintenance free batteries (AGM and gel cell) and ideal for use in long term storage to provide and maintain an optimal Connect It And Forget It: Once connected, the Battery Tender Charger manages your battery’s health on it’s own. Smarter than a trickle charger.
- Connect and Forget: Once connected, the Battery Tender Charger manages your battery’s health on it’s own. Smarter than a trickle charger, it automatically switches to float mode when finished initial charge.
- Easy to Use: A low maintenance design that's quick and easy to use, our universal power sports 12V battery charger is lightweight and compact allowing it to operate everywhere, even in small storage spaces.
- High Powered: Contains 50% more charging power than the Battery Tender Junior (021-0123) to supply a much quicker charge to your motorcycle, ATV, UTV, personal watercraft, or scooter to maintain peak performance
Smart Chargers: About $65 to $100
This is the sweet spot for most drivers. A 5 to 10A smart charger recharges a flat battery overnight and maintains it afterward.
- MEET THE GENIUS5 — Similar to our G3500, just better. It's 34% smaller and delivers over 65% more power. It's the all-in-one charging solution - battery charger, battery maintainer, trickle charger, plus desulfator.
- DO MORE WITH GENIUS — Designed for 6-volt and 12-volt lead-acid (AGM, Gel, SLA, VRLA) and lithium-ion (LiFePO4) batteries, including flooded, maintenance-free, deep-cycle, marine and powersport batteries.
- ENJOY PRECISION CHARGING — An integrated thermal sensor dynamically adjusts the charge based on ambient temperature, preventing overcharging in hot weather and undercharging in cold, ensuring optimal battery performance.
- CHARGE DEAD BATTERIES — Charge batteries from as low as 1 volt, or use Force Mode to manually charge completely dead batteries down to zero volts. Perfect for recovering deeply discharged or neglected batteries.
- BEYOND MAINTENANCE — Keep your battery fully charged without worrying about overcharging. Our smart charger constantly monitors the battery, allowing you to leave it connected safely - indefinitely - for worry-free maintenance.
Chargers With Engine Start: About $105 to $200
These cost more because they can deliver a short burst to start the engine. They make sense if you often deal with dead batteries at home.
- STARTS DEAD BATTERIES FAST: Delivers a 100-amp engine start so you're never stranded by a dead car, truck, or motorcycle battery.
- CHARGES AND MAINTAINS ON YOUR SCHEDULE: Switches between 30-amp to 12-amp boost charging and 6-amp to 2-amp 12V or 2-amp 6V charge-and-maintain modes, giving you fast power when you need it and safe, long-term trickle charging when you don't.
- WORKS WITH VIRTUALLY ANY BATTERY: Compatible with 6V and 12V standard, AGM, deep-cycle, and 12V lithium (LiFePO4) batteries across gas and diesel vehicles, so one auto battery charger covers your car, truck, SUV, motorcycle, ATV, and marine batteries.
- DIAGNOSES AND RESTORES BATTERY HEALTH: Built-in battery and alternator testing, plus an advanced desulfation mode, help you catch problems early and revive batteries that have lost their charge.
- COMPLETE PACKAGE: Includes (1) SC1308 Battery Charger, (1) User Manual
Is a Charger Cheaper Than Replacing a Battery?
Often, yes. A charger can bring back a battery that was drained by lights left on or long parking, and a maintainer can help batteries last longer by keeping them charged. But no charger can save a battery that’s worn out. AAA says batteries typically last three to five years, as cited by Consumer Reports.
How to Avoid Overpaying
- Buy for your real use. A maintainer is enough for storage.
- Don’t overbuy amps. 5 to 10A covers most cars.
- Skip engine start unless you need it. A portable jump starter may be more useful on the road.
- Check included accessories like ring-terminal leads.
