ChargeMend has kept my car's battery topped off all winter without any overcharging worries. I just connect it and forget about it. No more jump starts, no more stress.

How It Works
How It Works
- Connect the clamps to your battery terminals, matching the polarity markings.
- The built-in microprocessor auto-detects your battery type and sets the ideal charging profile for you.
- Walk away and let it work. ChargeMend switches to a safe maintenance mode the moment your battery is full, so it's fine to leave connected.

Based On Real and Honest Experiences
My motorcycle sat all winter and the battery had gone completely flat by spring. ChargeMend's pulse repair mode slowly brought the old, sulfated cells back to life, and now it just keeps the battery topped off between rides.
Jessica T.Verified Buyer
I keep ChargeMend connected to my boat battery all winter in storage, and it always starts on the first try when I'm ready to head back out on the water. No more dead battery surprises at the marina.

Q1 Will this actually charge a dead battery, or just maintain it?
Yes. ChargeMend fully charges a depleted battery first, with most batteries recovering in 4 to 8 hours, then automatically switches to maintenance mode to keep it topped off long-term.
Q2 Does it work with both 12V and 24V batteries?
Yes. ChargeMend automatically detects whether you're charging a 12V or 24V system and adjusts the voltage accordingly, so you never have to guess a thing.
Q3 What happens if I connect the clamps backwards?
No damage done. The reverse polarity protection instantly flags the error on the LCD screen and halts charging until the connection is corrected.
Q4 How long until a dead battery is fully charged?
Most batteries recover within 4 to 8 hours depending on size and condition, and you can watch the exact progress live on the display the whole time.
Q5 Will it work on my AGM battery in a motorcycle or boat?
Yes. ChargeMend is built for AGM, GEL, and lead acid batteries and auto-detects the right profile, so it charges just as reliably in a motorcycle or boat as it does in a car.
Q6 Can it actually revive an old, sulfated battery?
In most cases, yes. The pulse repair mode breaks down the sulfate crystals that build up over time, restoring lost capacity in many older batteries.
Q7 How does ChargeMend compare to big, expensive name-brand chargers?
ChargeMend uses the same core microprocessor and pulse repair logic found in premium chargers, without the retail markup of big-name packaging and advertising, so you get comparable performance for less.
Q8 Is it safe to leave connected all winter or for months at a time?
Completely. Once your battery is full, ChargeMend switches to a gentle maintenance mode that guards against overcharging, so it's built to stay connected safely all winter or for months at a stretch.
