4A 6V/12V Automatic Smart Battery Charger by ATEM Power

A flat battery has a way of showing up at the worst possible time, whether it's a caravan house battery that's sat idle over winter or a boat battery that hasn't seen a charge since the last trip. This ATEM Power 4A smart battery charger is built to stop that happening, cycling 12V and 6V batteries through a full 10-stage charge and then settling into maintenance mode so they're ready whenever you are.

It's set up to handle the mix of batteries you'll actually find around a shed or 4WD: 12V STD, AGM, GEL and LiFePO4, plus 6V STD. Select the right profile, connect up with the included clips or terminals, and the charger takes care of voltage detection, mode switching and cut-off itself. Even a LiFePO4 battery that's dropped into a low-voltage sleep state gets a dedicated wake-up charge program rather than being written off.

Because it's designed to stay connected long-term, it doubles as a maintainer for anything that spends more time parked than driven. It runs from a standard 220-240V AC outlet, remembers your settings through a power interruption, and reports status, charging stage and any fault codes on its LCD screen so you're not left guessing at what a blinking light means.

Features

10-stage automatic charging: detects battery voltage and runs 3 to 135Ah batteries through a full 10-stage cycle without any manual switching.
Multi-chemistry compatibility: dedicated profiles for 12V STD, AGM, GEL and LiFePO4 batteries, plus 6V STD.
LiFePO4 wake-up mode: brings sleeping (over-discharged) lithium batteries back into service via a dedicated 14.6V DC / 2A charge program.
Safe to leave connected: designed for permanent connection, so it works as a maintainer between trips, not just a one-off charge.
Built-in protection: guards against short circuit, over-temperature, overload, over-charge/discharge, over-current/voltage and reverse polarity.
Tough housing: flame-retardant ABS casing with an IP65 rating, plus CE, GS and RoHS certification.
One-button LCD control: a single button switches modes, with battery status, charge stage and fault codes shown on the screen.
Charge memory: keeps your selected settings and resumes automatically after a power interruption.
Ready-to-connect leads: comes with a detachable SAE connector plus O-ring terminal and alligator clip leads.

Frequently Asked Questions

Can a smart charger charge an AGM battery?

Yes. This charger includes a dedicated 12V AGM charging profile as part of its 10-stage program, cutting off at 14.4V (+/-0.3V) once the battery is full. Selecting the correct profile for your battery type before connecting helps the charger apply the right voltage and current throughout the cycle.

What does AGM mean on a smart charger?

AGM stands for Absorbent Glass Mat, a type of sealed lead-acid battery. Selecting the AGM setting on this charger applies a dedicated multi-stage voltage and current profile suited to that battery type rather than a generic charge.

Does an AGM battery need a special charger?

AGM batteries generally do best on a smart, multi-stage charger that matches voltage and current to the battery rather than applying a flat charge. This ATEM Power charger is designed for that, with a dedicated 12V AGM profile alongside STD, GEL, LiFePO4 and 6V STD options.

What size batteries can this charger handle?

It's rated for batteries from 3Ah up to 135Ah across its supported chemistries.

Can I leave this charger connected to my battery long-term?

Yes, it's designed to stay connected permanently, so it can be used as a maintainer between trips rather than only for a one-off charge.

Can this charger revive a fully discharged LiFePO4 battery?

It includes a dedicated wake-up program for sleeping (over-discharged) LiFePO4 batteries, charging at 14.6V DC / 2A to bring them back into service. Very deeply discharged or damaged cells may still need assessment by a battery specialist.

Is this battery charger waterproof?

It carries an IP65 rating, meaning the flame-retardant ABS housing is protected against dust ingress and low-pressure water jets from any direction. It isn't rated for submersion, so avoid locations where it could be fully submerged or left exposed to heavy rain without cover.

What happens if the power goes out while it's charging?

The charger has a charge memory function that keeps your selected settings and resumes the cycle automatically once power is restored, so a blackout or brief disconnection won't reset it.

Why Shop at 4x4 Down Under?

We know that you have a lot of options out there, and we’re incredibly grateful that you’re considering spending your hard earned money with us. We like to think we stand out from the crowd in a few ways.

Excellent & Honest Service

We try and provide the best pre and after sales service possible. If you have a question we’re here to help, and if we don’t know the answer we’ll tell you and then do our absolute best to find the answer for you. We’re also here to guide you to the best possible outcome for you. A lot of stores will simply try to up-sell you on the most expensive option. That’s not how we operate. We want to build a relationship with our customers, and the only way to do that is by being honest and direct.

4x4 Down Under is built on honesty and integrity. For example when you make a purchase with us we only charge your account once we confirm the product is ready for dispatch. Although we like to guarantee everything on our store is available we’re not perfect and mistakes do happen. If something turns out to not be available we’ll let you know immediately and you have the option to cancel your order or wait for more stock to arrive. Should you not want to wait the order is voided, and there’s no waiting a week to get your money back (it’s instant!).

Aussie and Proud!

We're Australians, and we like to support our fellow Australians, which is why all our products are sourced locally from the official Australian distributors. Nothing is imported directly and we don't stock any grey imports. This also means that all manufacturer warranties are fully honored by the brands themselves.

No Sales Gimmicks

When you shop at 4x4 Down Under you don’t have to worry about:

Annoying and dishonest ’Sales Timers’ that simply reset every few hours and are there to coerce you into buying.
Dishonest “low stock” labels, another coercive sales gimmick.
False “John just bought a…” alerts. Our customer alerts (bottom left) are 100% true and we're proud of them.
Being bombarded by trust badges and labels everywhere you look that mean nothing.
We don't spam! Your information is safe with us. It will never be shared or sold, or used to fill your inbox with garbage.

Fast Shipping with Insurance!

We've partnered with some of Australia's best couriers and freight agents to ensure your purchase reaches you in super-quick time. Once your order has been dispatched you'll receive tracking information which will allow you to track your order online every step of the way. And if something should happen to your order while in transit you can rest assured that it's insured and you won't lose a dime!

If you still have any doubts feel free to give us a call on 1300 76 86 41, or contact us here. We'd love to hear from you.
