NOCO Genius GEN5X1, 1-Bank, 5-Amp (5-Amp Per Bank) Fully-Automatic Smart Marine Charger, 12V Onboard Battery Charger, Battery Maintainer and Battery Desulfator with Temperature Compensation

They don't fit Australian plugs without a adapter great unit but the plugs let them down you should not have to rewire for our plugs the company is very shot sighted on this matter

Bought this for an onboard maintainer in a diesel pickup. Mounted it on the ledge above the brake fluid reservoir with 3 M heavy duty outdoor velcro. Close to the battery and rock solid. This velcro has adhesive that rivals super glue. Be sure you have it where you want it the first time. ( ask me how I know). Ran the wiring in semi rigid loom and connected the ring terminals to the battery bar. Plenty of wire included ( 6 feet each for power and battery wires) . Connected the power cord to a waterproof external receptacle mounted under the vehicle's bumper. Works great, fully automatic. Returns to your last setting for battery type. No need to open the hood and select battery type each time you plug it in. For the quality, it's a bargain. Short trips or long periods of storage in a diesel are hard on batteries and they're expensive. This maintainer is cheap insurance. I plug it in about once a week and it takes about 2 hours to top off the batteries. It balances the parallel batteries perfectly, both at 12.7 volts when finished.

Is a solid product and it’s waterproof.

Amazing build quality as always for Noco. Pretty heavy and rigid brick . On my test stand was an AGM battery brand new 70AH 710 CCA 120RC. Charger outputs 4.7 - 4.8 Amp max. Battery was as low as 10.8 V, supplied max current quickly, took about 12 hours to charge full. Gets pretty worm mostly on the back side.

Incredible charger, well worth the money. I've used it on AGMs and acid batteries and works great. I had 2 AGM batteries that had zero voltage and the charger is able to push a charge to the batteries long enough to trigger the charger to get them back to full capacity. Quality is great, it's compatible with every automotive battery on the market and helped bring back numerous batteries instead of me having to go buy new ones. Well worth it.
