Car cannot start? Pump not working? Engine conked 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 an 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.
