All units stopped working December 2024
I have 5 of these unit’s monitoring batteries at 5 different locations across Arkansas. They were initially a pain to pair with WiFi but once accomplished worked flawlessly. All 5 units at all 5 locations ceased operating December 16th 2024. I can only assume the company has decided to discontinue whatever is necessary for these units to operate. That is pretty low down and scummy. These units were purchased with the expectation they would operate and I certainly held up my end of the bargain by paying for them. The company should issue refunds to everyone that purchased WiFi units. I will never purchase another product from this company again and will make it a point to dissuade others from doing the same.

WiFi DOES NOT WORK AT ALL
It is impossible to connect any of their devices to WiFi in 2025. They should not be marketing this as a feature anymore. Honestly they probably shouldn’t have been marketing this as a feature 5 years ago because my 8 year old router, 5 year old router, 2 year old router, and my now brand new professional grade network setup all failed to be compatible with their devices. I have done everything possible to make it work but it flat out DOES NOT WORK with any network. I set up a completely separate WiFi network with my old router all only broadcasting on the 2.4Ghz network and it failed to connect to them so I went so far as to create a separate 2.4Ghz network just for their devices on my current brand new setup now that I have a whole server room and it still flat out does not work. If I cannot make it connect to a custom made network specifically created for their devices then it clearly only will work on very specific hardware most people will not have anymore if they ever did have it. They need to remove the WiFi advertising from the boxes and marketing or they need to fix this because currently it is false advertising at best and malicious marketing at worst.

Works great!
I have 3 monitoring devices and 2 10A chargers. The devices and app have been working great for years. I’m not sure why so many people rate this so low. I did setup a 2ghz only wifi network for all of them, so maybe that’s why they’ve worked so well. I’ve had to reset and add my 10A chargers once or twice in the last several years but the monitoring pucks that plug in to the battery haven’t had any issues. The only major problem is that I don’t always receive low battery notifications. I really wish they would update the app and maybe add a refresh button.

Wifi doesn’t work at all.
What’s the point of this $130 maintainer if the smart function doesn’t work. I have mine connected to the 2.4 gHz IOT network on my mesh router, and all the app ever says is “updating.” I bought this so I could monitor the lifepo4 battery on my collector car. It does me zero good if the app doesn’t work. It’s getting returned to lowes. I’ll go back to my dumb Ctek.

Works
Honestly, I didn’t have the same experience with this app as other people. I did have to look up the default password and that could have been in the app, but it reads out voltages and amps for me which is good enough.
App does not work at all
As of the time of writing this, the app has not had an update in 3 years. The sign up page is broken, signing up through battery tenders web page and then trying to use that log in doesn’t work either. I wasted a solid 45 min trying to get it to work before giving up :(
Don’t Bother
Don’t bother buying this version of the battery tender if you want to use the wifi. It’s absolutely useless as it will not connect. The internal guide and provided instructional manual have 2 different networks stated. Only 1 pulls up and does not connect to it. Tried a million times and simply will not work, just loops you in circles on settings. Wifi is a joke.

Can’t connect to hidden network
I don’t broadcast my network and would like to keep it that way. Please add a way to manually enter a network instead of relying on broadcasted SSIDs.
Help button in app sent me to a 502 bad gateway error page. That needs to be fixed as well.
Charger works, the additional tech part needs to work too for satisfied customer experience.

Works great on 10A
Had to reset wifi connection once, but has worked fine for 2+ years. No complaints.
Zero stars for WiFi
Charger itself seems to work fine. WiFi will not connect at all through newer iPhone updates.
I bought this on clearance for a great price. I’d still return it if the WiFi was a major selling point for me. It isn’t, so I’ll continue using it as a standard charger that I got a great deal on.

10A tender works for me
WiFi connect was a bit painful, and it lost the connection one other time. However, it has worked flawlessly from that time forward (2+ weeks). Screen updates are a bit slow, but usually happen in 30 seconds or less. Note that I do have a WiFi router in my garage, so that probably helps; even though it is more than 10 years old.

Garbage is an understatement
Took me 100 tries and a lot of patience to get this trash connected and when it did it didn’t operate like it was supposed to. Couldn’t connect it to the home Wi-Fi like advertised so my phone had to be connected directly to it if I wanted to do anything. Fast forward a year later won’t let me connect at all. Got some satisfaction utilizing my 5 lb sledge on the battery tender and just hooked up a charger that doesn’t require wifi.

Won’t connect to the charger
When I connect to the charger WiFi network the app does not acknowledge the connect and I can not continue the connection process.
No passwords allowed
All the reviews led me to believe it would be clunky, but I didn’t expect the required user registration to not work.
No passwords will be accepted. Rules are one number, lower case, and uppercase. No passwords are accepted. I can’t register, so I can’t use the app.
Worse than 1 star.

Terrible app/ doesn’t work
After spending a couple hours messing with this app, it’s just junk and doesn’t work! I paid more money for a wireless ability for my Battery Tender just to end up with an app that doesn’t work. Shame on this company for not fixing this thing over the last couple years! Don’t offer Wi-Fi if you app is junk.

Cannot register won’t validate password field
Can’t review. Can’t get registered. No matter what I use for a password. Yes I have capitalized and lowercase yes I have numbers and yes it’s between 8 & 24 characters. Just fails highlighting the password rules and not activating the register button
Completely useless
This is the worst app I’ve ever had. Not only does the charger I bought not connect to 5Ghz networks, the app won’t even connect to the charger at all even with 5Ghz turned off on my access point.
It’s companies like this that give “smart” devices a bad name!

Useless App
Bought the charger today. Can’t register online since it will accept my password although I am complying with the requirement: 1 Capital letter, 1 number and the rest are small case. I bought it for this specific feature to monitor the charger from my phone. Obviously, the developers have no idea what they’re doing

Worthless APP
Just purchased the charger and downloaded the app. I can’t even register with the app.
Even though I followed the instructions I can’t get past putting in a password.
This app is a absolute waste of time.

Doesn’t work at all
Followed the instructions for wifi app and connected to the wifi per the in the box instructions . However the app (despite being connected to the product wifi) won’t recognize it . Keeps saying the wifi start with a BT but the wifi starts with a number . Also the charger itself is way to confusing the manual doesn’t explain anything ! I can’t even find out how to keep it on despite not being plugged in, which mamps to choose nor which of the multiple power cycles I am supposed to be on. When you unplug the cord the device turns off so no way to charge the battery of your car . Awful product overall including the wifi
