CTEK (40-149) CTX Battery Sense - Smart Battery Monitoring via Mobile Phone Review

fished and didn't start the truck for several days just knowing the charge level even if the truck stood on the road for a long time in winter. And I haven't started the truck for a few days so I can install a Ctek Polar 4.3 amp charger if needed. I also like how easy it is to install, a very good product and I recommend it like my brother in Pa. also installed one on his rig.

I recently left one of my cars for a long time. I needed an easy way to check battery status so I could use my multi-car charger and a few small batteries for lawn maintenance and other uses. A month later, I received a message about the need for a top-up. You can use this device by plugging it in, fully charging it with a smart charger (e.g. CTEK), and then leaving it alone. You'll likely need a fully charged baseline to get started. I'm happy with that. I'm almost thinking of other vehicles…

I charged my battery to 100% with the CTEK charger and it was great. Unfortunately, after connecting this Battery Sense, my battery went from 100% to 78% within 12 hours. I have used this in another car and drained my battery from 29% to 23% in the same period. As you can see in the graph, I drove one of the cars for about 30 minutes and jumped from 3% to 26%. I'm not sure about the accuracy of this device, or it's just drawing too much current when connecting the battery clip. It's probably…

I have 2 CTEK battery sensors in a car to monitor my high quality car radio. One for the main engine battery and one to control my auxiliary shuriken battery in the trunk which powers my car stereo. I've read the complaints and encountered many of the same problems as you. If it works it's great, if it doesn't work it sucks. After experimenting with the various options and fixes recommended by the company, I found that Battery Sense can lose connection when your phone receives an automatic…

The device itself is quite easy to use. Normally connected to the car battery. Bluetooth connects to my Samsung S7 with no problems. However, the included phone app is very poor. Connectivity is often difficult. He often falls. It has screens that sometimes don't update. Chart readings are sometimes questionable and confusing. The graph shows the scale up to 100% (not the actual voltage reading) and is often off the graph so you cannot see the measurements. After fully charging the battery (or…

The product is excellent and the manufacturer CTEK is very quick to respond to questions via email. I work from home so I rarely drive my car long distances, mostly short trips of 5 or 10 minutes, to go to the gym or to eat. This is bad for a car battery and I bought this battery along with a CTEK MUS 4.3 charger to make sure my car batteries don't run out. A few things to know: 1. In most American cars, the size of the battery post nut is 6mm. 6mm nuts are also listed as "M6" in places like…
