It can check and read checking status at anytime. Important, the build in timer accurate show the charging time. Delivery was seamless. It is one of best charger that ctek ever made. Importantly, the adapter work and connection work 100%. Review: Does not keep battery conditioned - Do not trust this to maintain your £1700 (+ labour) li-ion battery in a Porsche 911 (992). It'll charge it fine but I was under the impression that it then enters a battery maintenance mode to keep the battery conditioned. It doesn't. This was a very expensive lesson. I have now bought the official Porsche Charge-o-mat Pro charger, which ironically is also made by CTEK and clearly does enter a maintenance / reconditioning mode to keep the battery healthy during long periods of un-use. ## Features - The next generation of smart charging: an enhanced, award-winning design now with Wi-Fi for complete remote control via the CTEK App - Total App Control with Wi-Fi & Bluetooth: Monitor charging in real-time, view detailed history, and get notifications so you never miss a charge - Adaptive charging technology (APTO): Automatically recognises battery type, size, and health and delivers a fully customised program for any 12V lead-acid or lithium (LiFePO₄) battery - Powerful Simplicity: No buttons or modes to select.

I don’t use the Benz 63s 2020 for 6months, would go flat in 3-4 weeks with the connected apps etc. This keeps it low voltage topped up. Brilliant. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seamless delivery *by A***R on 4 April 2026* This charger work differencely compare with regular Ctek. It can check and read checking status at anytime.
