Used it on my F-150 lead-acid, my Goldwing's lithium, and a 6V battery in my dad's 1965 Mustang — same unit, no extra plugs to buy. Plug it in and forget about it. I should have bought this years ago.

One Charger Handles Every Battery — No Adapters, No Guessing

All-Chemistry Mode Switch

One press of MODE selects STD, AGM, GEL, SLA, EFB, Flooded, or LiFePO4. Covers every battery chemistry in a multi-vehicle garage.

6V + 12V Auto-Detect

Charger reads battery voltage and sets output safely — 6V for the classic restoration, 12V for the truck. No hardware switch, no wrong-mode disasters.

8-Point Protection Stack

Reverse-polarity, short-circuit, overcharge, overload, temperature, voltage-spike, overheat, undervoltage guards. Hook it up backward, nothing fries.

Climate-Compensated Output

Internal sensor adjusts current from 10°F garage cold to 100°F summer heat. Temperature-compensated charging without paying double for the EU unit.

What our 9,700+ Customers say

Based On Real and Honest Experiences

Bought AmpForge for my Indian Chief sitting through a Minnesota winter. Garage hits -10°F and the last tender quit in the cold. AmpForge held the AGM at full all season on climate-compensated mode — turned the key in April and it started right up.

Warren K.· Verified Buyer

Eighteen months in. Lives on the workbench, gets clipped onto something at least once a week. Display still bright, clamps still grip, no quit. Holds the 6V Mustang and the 12V Chevelle with one button press.

Ray P.· Verified Buyer

I was skeptical on pulse repair — hooked an old AGM I was about to trash to AmpForge in Repair mode overnight, and it climbed from 10.2V to 12.6V across three cycles. Color me converted.

Sam R.· Verified Buyer

For what you get — lithium support, 6V mode, repair function, climate compensation, worldwide voltage — this is priced like a basic trickle unit. Compared four other chargers before buying and none did all of it.

Marcus D.· Verified Buyer

Husband travels for work so I needed something I could actually use. Press one button, clip two clamps, walk away. Works on the Subaru and the riding mower without any thinking on my part.

Linda J.· Verified Buyer

AmpForge changed how my whole garage runs. Three chargers, three drawers, a tangle of adapters I never found when I needed them. Now one unit handles the truck, the bike, and the boat without a single adapter.

Frequently Asked Questions

+164 expertsreviewed it

Once full, AmpForge drops to float mode and delivers only the trickle to offset self-discharge. Hook it up in October and the battery stays at peak health through April — no sulfation, no over-discharge damage.

At 60W, a 12V motorcycle battery (8-12Ah) charges in about 2-4 hours. A 50Ah AGM marine battery takes 8-12 hours. AmpForge shows live voltage and charge stage so you always know where you stand.

The reverse-polarity guard cuts power before any current flows. No spark, no blown fuse, no fried ECU. You'll see an error on the display — swap the clamps and the unit resumes normally on the right polarity.

Yes. The unit auto-detects 6V vs 12V at the clamps. Pre-1956 GM, Ford, and Mopar 6V systems charge correctly without any switch flip. Same unit handles the 12V battery in your daily driver.

Repair mode sends high-frequency pulses to break sulfation off lead plates — the buildup that kills neglected batteries. Independent testers have seen AmpForge bring batteries from 10.2V to 12.6V over a few cycles.

Yes. The Lithium/LiFePO4 mode runs the correct charge profile for lithium-iron-phosphate packs, which need a different curve than lead-acid. Safe on the new bike, the lithium accessory bank in the boat, and lithium lawn-tractor batteries.

Yes — the input accepts anywhere from 100V to 240V, 50/60Hz. Use it in the US garage, on a European trip with a plug adapter, or on dockside shore power without a step-down transformer.

Yes. AmpForge handles that scenario — charge the truck Monday, move to the Goldwing Tuesday, plug into the boat Wednesday. Press MODE for the right chemistry, clip the clamps, and the unit auto-detects 6V or 12V.
