3.5A 12V/6V AGM Automatic SLA Smart Battery Charger

Car won't start? Pump not working? Did the engine conk out? And you realise that they all have a common problem. Flat battery. Now you can prepare for such unforeseen circumstances with our high-performance CT-3800, a powerful 3.5A Battery Charger that is compatible with all 6V and 12V lead-acid batteries and 12V lithium-ion batteries, including WET/MF/EFB/GEL/LIB/AGM batteries. Fully automatic and easy to connect and use, the charger is your godsend in bringing life to dead batteries.

The internal intelligent microprocessor makes charging faster, easier, and safer. It provides continuous charge to batteries with an automatic floating charge mode and there is inbuilt 6-way protection for sparks, reverse polarity, short circuits, overcurrent, overcharging, and overheating to protect both use and battery. This means safe charging with total peace of mind.

The charger comes with eight charging modes to suit your requirements. On REPAIR mode, the charger can even repair old, idle, stratified, or sulphated lead-acid batteries to bring them back to life. Portable and lightweight, the charger is equally useful to you on the road as it is in your workshop, garage, or shed.

If setting up in your workshop, you can easily mount the charger to your desired location using the mounting holes and included self-drilling screws. Never let your power down again as you power up with our battery charger.

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!).

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.

High Quality Products & Free Shipping

Aside from the above we also offer free shipping to almost everywhere in Australia (on any product over $150), have a great range of high quality products at excellent prices and LOVE what we do! 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.

Shopping with 4x4 Down Under: Excellent👍🏽
PROCAT 28 with twin OB’s no rollers on trailer!!

The Runva 11xs I decided to purchase from
4x4 down under is absolutely awesome!!
I initially tried a Powerwinch RC30...couldn’t pull the boat completely onto the trailer before the clutch would slip...very weak and build quality was embarrassing considering the price...
For anyone needing a ‘proper’ boat winch the
RUNVA 11xs is the way to go!!! Has the PROKAT
fully onto the trailer within 30 seconds flat!!!

Thanks for the great feedback Terry! The 11XS is a fantastic winch. Let us know if you need anything else down the track.
