SHENMZW-20 Battery for NETGEAR Nighthawk 5G WiFi 6 Mobile Hotspot Pro by AT&T W-20 MR5100 MR5200, MR5200-100EUS Higher Capacity Replacement Battery

Fits well, looks practically identical. No issues so far. I generally try to avoid leaving this plugged in to a charger once it reaches 100%. I think it's a product design flaw with the nighthawk modem that it keeps using battery while plugged in and keeps ring to charge the battery resulting in it getting hot. If I need to use it for an extended period I plug it in to power and remove the battery.

My local battery place was going to take 2 weeks to get this in so I ordered it here and it came in 2 days. It was a perfect fit and hasn't overheated like my old one.

I feel like the battery life could be better for a new battery. Charged about 10 times now and expected it to improve as lithium batteries tend to do. Brightness is down so there shouldn't be to much drag on it, but still play 3hrs kills it

Replacement battery for my M6 Wi-Fi system works good

Battery life is great ..

Battery already dead after three months. Not good at all.

this is the 3rd battery I have tried from Amazon. all 3 overheats and shuts the router down. this last one lasted one month pass the return date. Junk.

Ended up not using it. Determined it was not battery. I assume it works as it should.
