How to replace battery on ZTE Warp Connect Hotspot?

The battery on my ZTE Warp Connect Hotspot appears to be swollen after about 5 months of use. I bought a replacement but I thought I'd seek out experts (safety first). I've removed the back cover and know that the battery is held by adhesive but it seems to be stuck very well. How much force can I use with a debit card/screwdriver before worrying about puncturing the battery?

After the battery is removed but still connected do I have to remove screws or the other panel to disconnect and reconnect the new battery?

Is this a good question?

I have same issue with Sprint warp connect battery swelling...my device keeps shutting off ....new replacement on the way....i ordered mine from amazon

I am reading this because OUR ZTE battery has swollen up - and when we called the guy at Batteries Plus to see if he had a replacement t, he said HIS battery was swollen - so what is this? What with all the batteries swelling up?

After a long process of going to Sprint store I bought it from, then sent to Sprint service center, then told they can’t fix it and given 800 number for ZTE Warranty dept I came to the conclusion that they want to screw all their customers over. Obviously there is a manufacturing issue with the swollen batteries- all under the 1 yr factory warranty. By the time I got off of the chat online rep I was down to sending my unit in so they could decide if I damaged it and would have to pay for repairs or it actually is a defect in which they would repair it and send it back. The length of this process for turn around.....about a month!

I have had the same issue and I am on my 3rd ZTE connect. It is a defect in the battery and all they do is give you the run around time after time. It’s starting to get really old. They blamed me for keeping it plugged in too much but that isn’t the problem. The problem is that their equipment is junk. I will not be getting a 4th. I’ll switch to someone else.

I changed the battery today. But it was glued in so well I was afraid to break the modem getting it out, but i was also afraid the battery would explode soon, so I carried on picking and prying at it with a nail file til i got it out. I have photos of the process if anyone want to see what it looks like before they crack it open. the side where the battery is stuck does not contain any major fragile parts so its ok to poke and scrape at the glue on the underside of the battery to get it loose. after that its just 5 tiny screws, replace it, and put the case back on. I did not use the adhesive with the new battery in case i need to replace it again.

Hey Beau, my warp connect also recently started swelling. I took the hotspot apart to see what was involved in replacing it and it is pretty straight forward. After you pry the battery up you will have I believe 4 small Phillips screws to take out because the battery connector is located on the opposite side of the board. After that its just a simple snap connection. Just curios where you got your battery from, only place I saw was alibaba.

I have had my warp connect for over a year. Of course it had a 6 month warranty. The Battery is bloated and it forced the back cover open. I am using it right now. I am going to replace it soon. I will be getting a FRANKLIN WIRELESS R850 MOBILE HOTSPOT for $80 from PCs for People.

Good Day;

Work a credit card or similar under the battery.  Takes a bit of work and is accessed after removing 5 screws.

Four are clear one is covered in the centre to the top.

This I have done but having a problem removing battery connection,  Seems it may also be clued in place.

Not sure which direction I should work the connection,  Any advice appreciated

Pull the connector up and away from the board, it isn't glued in but it is a bit annoying to get it to pull away

These things seem to be very sensitive to over charging. Probably best to use a power timer that only charges it occasionally. Mine swelled so much that the back popped completely off and wouldn’t stay closed except with rubber bands. Eventually, the battery became pretty much useless and it would constantly reboot whenever it was  unplugged.  I bought an old one from eBay to swap batteries. Of course, pulling the battery is a pain because it's glued down (work a credit card under so you don’t pierce it). Then there is hardly any wire length to work with and the connection doesn’t slide off parallel to the circuit board as it might appear. You need to lift or pry it up off of the circuit board. Since there is almost nothing to get hold of, it’s best to slide a paperclip under the wires of the plug and carefully pry them up (pressure perpendicular to the circuit board) by lifting there and it should pop off.  Also, the back just pops off, but remove the SIM card and all 5 screws before popping off the front.

I've been using a power timing since I bought my Hotspot 18 months ago. I found the battery terribly swollen on Tuesday and ordered a replacement from Amazon Prime for $14.65 It was delivered in Thursday and the install took maybe 40 minutes.

I changed mine today with a normal hard case battery with the same exact specifications. I left it turned off until the battery charged. Then I turned it on and connected to it That was 3pm, it’s 9:26pm now and it’s only 1/2 way drained 2 of 4 bars left. The steps I took:

I turned it off, removed the SIM card & tray.

Took the back cover off.

Started with a thin plastic Key Chain card (those small membership cards like Rite Aid etc.) it’s small and you can maneuver it around.

I worked it under each corner then worked inward until I had it pretty well loosened.

Then I used a full sized (wallet sized) plastic card.

It popped right out.

Then I used a small philips screw driver to remove the 4 visible screws.

There is 1 more screw that has a felt like cover over it. Once that one is out carefully separate front panel it clicks in & out just like the back cover.

Once that is off you’ll see the plug with the 3 wires Red top green middle black bottom.

The plug is snug and lifts off. It doesn’t slid off. The bottom of the plug/connector is slotted so it pops off.

Then put the new battery in guide the plug & wires through the hole, line up the connector red wire top and press down on the plug and it will pop into place.

Put the front cover back on. Turn it on to make sure it’s working, turn it back off, then put the screws back in. I put the felt cover back on the covered screw. It probably there for a reason like preventing shorts or something.

Put the back cover back on.

Put the SIM card tray back in.

Plug it into the charger with the unit off until it charges to 100%.

Remove the charger, turn it on and your good to go.

Thin card vs. credit card suggestion helped, my library card and my insurance card worked very well.

Your hint of where the 5th screw was hiding (under a dot of felt) helped, thank you.

The wire connector is easier than it looks - just pop it off is probably the best description.

This is the one I bought, but it’s swelling again.

This is for the 910 model but it works just fine until it swells again.

New LI3823T43P3H715345 Battery For ZTE MF910 MF910S MF910L 3.8V 2300mAh 8.8Wh

i actually am getting a different hotspot entirely and will likely try to sell or throw this one out. The service I have isn’t great and this hotspot kills the batteries and also is very inconsistent. Sometimes I have to reboot it just to have signal (in the same location)

This picture (link below) is of the old battery in the new battery packaging and the new battery in my ZTE 920VS. It’s working flawlessly and no heating or swelling.

I guess I got lucky. Is the new battery you have a black hard case battery or a foil type like the original?

Thanks for the quick informative replies . I have the foil type like the one in your pic. This looks what I need. I'll grab one off of ebay and follow the instructions for replacing it as stated above in prior posts. Thanks again!

I had a foil type as my replacement and I probably should've gotten the hard cased battery like you did

Hello,

Could you tell me the model number of your new battery? I clicked on the link to amazon but just got a general listing of batteries. I’m trying to figure out if I need to use a specific replacement battery or if there is another battery I can use to replace the old one in my ZTE Warp Connect Model: MF920VS.

It’s exactly the same as the old one which is :

Li3823T43P3h715345 Battery for ZTE 2300 mAh 8.8 Wh 3.8v

It’s the same part number and specifications as the original battery but it’s not the same cheap foil construction which swells.

The company is called Cameron Sino. On the label it says replacement for the Grand S Flex.

There is a reference number CS-ZTF230SL. It’s a great battery. It has no problems with over heating or swelling and lasts a long time between charges. I hope this helps.
