Safety Cautions1. Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they are not properly recharged or used.
2. Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
3. Do not mix use old batteries with new ones, avoid using batteries of different brands.
4. When buying lithium battery, should make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
5. Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
6. Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.

Good Coverage But...
Asurion had me to package up my Ipad and send to them to research the problem with it overheating and cracking the screen near the home button. The turnaround was about 6 days from when i shipped it next day and them returning the device. When I began to setup the IPad the first thing I notice was an error message stating touch id could not be setup on the device (it worked previously) and the ipad still got hot when charging. I had to return it to them a second time to "resolve" the issue. They determined they couldn't fix the issue and returned the cost of the device. The only problem is you can't replace a device for what it cost at that time of purchase, especially now when prices have soared. They need to fix or replace the device at the cost of what iit costs at the time of replacement.

They sent me a Amazon gift card
I insured an iPad for my son and had it repaired multiple times from him stepping on it. Quick and fast repairs. The last time he accidentally damaged it they sent me an Amazon gift card for the full price I originally paid for it. I was able to use the gift card right away because it was digital. I used it on an iPad that was on sale for half the original price so I was able to get him the night light he always wanted.
Best service available and I insured this iPad right away with them.

They will do anything to get out of fixing or replacing your item.
I bought a refurbished Samsung Galaxy Tablet S6 from Amazon through Affirm. I've already had the tablet for nearly 3 months. The tablet is defective. After barely 3 months it won't charge. I attempted to file a claim. The Asurion website tells me to return the item. Samsung doesn't make these tablets anymore. You cannot buy a brand new tablet of this model. They aren't sold online. The reason I bought the warranty which was over $100 is so that Asurion will fix the tablet if there is a problem. They were unwilling to make any effort to repair or fix this rare tablet. The website says to return the item. This is a lengthy return process. Amazon will not give me a QR code or let me print a label that I can take to a local UPS store. The only place Amazon will let me drop off the item is 2 or 3 towns away. The only option Amazon is giving me is to have UPS come pick up the tablet without giving me a label. I had to purchase a box from UPS and have them package it for me without providing me a label because Amazon says I don't need one. On the first attempt the UPS guy wasn't able to pickup the item because they need a special kind of form and my UPS driver didn't have the form. I have to wait until a UPS driver with the proper form is able to pick up my item before they can start the return process. Now I can't buy a Samsung Galaxy Tablet S6 from Amazon unless I want to go through this or a similar process every time an Amazon 3rd party seller sells me a defective product. Thanks for nothing Asurion. I'm going to start buying my electronics in person from Best Buy. They sell electronics that work and they immediately replace damaged and defective items that are under warranty. Amazon should ban Asurion from selling warranties on their website. They are selling warranties that they have no intention of providing the end product for. This is the second I've had a problem with Asurion. The first time I had a problem with a pair of headphones purchased through Amazon that were covered by my Asurion warranty that I had purchased. Asurion wouldn't help me and directed me to try and use the manufacturer warranty. When I buy a warranty from someone it's because I want the seller of the warranty to solve my problem. Not tell me to return the item or direct me to use the manufacturer warranty. It's not my fault the refurbisher couldn't make the tablet function properly for longer than 3 months.
