CTEK Battery Sense

both the device and the design, as well as the idea are very good. However, the calculation algorithm is too pessimistic about the real state of the battery, it asks too soon to charge the battery. In my case 12V 75ah car battery.

I use 3 units since mid 2017, until 2019, very SLOOOOOOW Bluetooth connections. Now with IOs 12.4.8 or IOS 13 no connection at all (the 3 units). Screen only displays “updating” for ever. Quitting App or restarting iPhone or iPad does nothing. Needs FAST update on App/firmware to be usable. Testing Tonwon battery tester Bluetooth

La primera sincronización es lenta para actualizar los parámetros de la batería (ah). Después la lectura es muy rápida. Pasando por el coche desde a 5m da la lectura. Totalmente recomendable.

He comprado el aparato battery sense y qno funciona la aplicación con el sistema operativo iOS 11. Espero que pronto lo solucionen y gracias.

Funcionaba hasta la ultima actualización donde ahora la aplicación se cierra inesperadamente.

If I could give this no stars I would!! It will not connect to iPhone 11 (2 different phones) or an iPhone 13. I am unable to get it to connect with all 3 handsets. Will connect to a Samsung s20+. Do not purchase this it is a discontinued product. I have purchased a ctek 25 amp charger and a 20 amp dc to dc however due to the lack of support and response from ctek I’ll be going with redarc in the future sorry you’ve lost me ctek

The temperature of my battery is currently 12.8 V And the level of charge is currently 30°C Screenshots available on request

I made the mistake of purchasing three of the CTEK devices for vehicles owned by various members of the family. Total waste of about $300 (Australian). Their software is rubbish and never worked reliably with any of the three devices. Their tech support is a joke and when they eventually responded to complaints they kept promising that they would fix the problems. Never happened. Now I have been contacted and told that all of my CTEK devices will no longer work because they have “old firmware”.

Not at all easy to install, must accept terms and conditions and then asks for permission to share dat a, no tick box to progress installation

App has stopped working. And no fix? Have reinstalled, tried on different phones with no success, just a frozen screen with no live info .
