Some comments from 2010 referenced EXPLODING batteries. This is 2015. Is this still happening?

way too expensive. My D40 battery was like 40 and I was pissed back then. Wow, inflation is getting ridiculous.

Im thinking like high as in uninhabitable. Lithium Ion produces gas, and is volitile. We has a transponder go off at work, it was sending a distress signal, the person "in charge" told us ti disable it by crushing it with a metal flange...Whoosh A Fire broke out!

If it is airtight and charging, it will probably blow up, seen it happen before, moved an entire wall. The challenge with sealed batteries is they are not really sealed, they have an exhaust port. Mostly what they give off is hydrogen and oxygen when charging and discharging and they then regenerate these gasses when charging. Charging too hot and fast means your gasses leave the battery and don't come back, so there is less charge. My nonprofit, MobilityMedicalProject.org is now an MK dealer, and I recommend them much more, plus they are guaranteed to be fresh and not new and sat on a shelf for 6 years.

I am sorry to report that something must have changed with production since June of 2013. I performed the exact same test that V.Bolinder did, and mine is dead. I opened it to see if, as others have mentioned, the panel was not attached. Oddly enough, it is soldered onto the board just fine. IN my opinion, the battery is not a rechargeable button cell. I am going to purchase some rechargeables of this size and replace, see if that works.

I don't know if it's still true about rechargables, but it used to be that they were not as much voltage as regular batteries. This is why they were not recommended to be used in cameras, or other items that have to run multiple features in order to really 'work' right - like date/time or flash, etc. Something like this shouldn't have an issue in that way.

I normally waited until I got a low battery indication. However, I don't believe that modern lithium-ion batteries have a "memory" like many of the batteries of a decade or two ago.

No idea, probably time for you to get this battery out of you cel phone. Nobody should this battery, apparently the seller or Amazon care about the safety of buyers. This battery get so hot to levels that are clearly very dangerous and it had been reported here and the seer still offer this trash in Amazon.People need to start paying attention to reviews, that's the purpose of it.

Sorry I cannot speak about that particular model as I purchased the ExpertPower 12v 5 Amp rechargeable battery. I do not see any mfg date on this product, but I can say it is working like a champ since I installed it on 3/21/2015. I am using it to replace the existing battery that went bad in my home alarm system after 15 years. The battery you mentioned is a little larger in width and depth than mine. It also has more power if the power to your alarm goes off.

Mine just arrived on 16 June 2015 and the code on them are 1215 meaning they were made just a few months ago in the 12th week of this year 2015. Very fresh batteries. Good for 10 years.

The outside box has no date on it. Each individual battery is marked with a "Best Before" date of March 2018. I purchased them January 16 2014, so it is a safe bet that current batteries will have a different date. For what it's worth; These batteries have exceeded my expectations. I have a number of wireless motion sensors that are in relatively high-traffic areas during the day. Previous batteries of another brand, always alkaline, never lasted more than about 5 months in those devices. These batteries, put into use January of 2014, are still going strong as of October 16 2014. The outside box has no date on it.

I ended three years of use four months ago and my battery is now dying out as well. I used to finish my lawn with one charge, now it takes two. I am contemplating the purchase of another battery, but at $149 it is definitely causing some sticker shock.

nope, I tend to use lipos which are even more dangerous but I do charge my batteries with a proper charger, not the one that came with this car. the NimH is pretty safe, it does heat up quite a bit while charging but hasn't set anything on fire yet.

Well, I didn't read that but to answer your question(s), No and No. I believe it must have meant that it would withstand an explosion. There is nothing inside that would cause it to explode, well except maybe the battery(s). If you charge them or if you change them I believe you shouldn't have a problem.

All four of my batteries became swollen after 2 1/2 years, some slightly, some noticeably. I disposed of all of them. Swollen batteries cannot be used as there is a risk of damaging the phone or in more serious cases, exploding.

Mine were the ones that did not work only after a few months. I cannot answer your question. However if they are not being used the batteries should not be draining to the point that when you need them in a real live EMERGENCY they don't work! You don't have the luxury of stopping to switch out the batteries. My units are being replaced, but if this happens again I will certainly be calling Wagan again! These are new on the market and in my opinion maybe they shouldn't have been launched until ALL of the bugs were worked out. Not let consumers be the guinea pigs!

I must AMMEND my former statement!!! A DUMMY battery is NOT A DEAD one. They are actually sold as dummies by companies and are cheap. I was lucky enough to have been corrected by RbwNY on July 7th. He/she informed me of this and added that pairing a 'dead' battery with the Li-on s can cause damage, etc. to the equipment. I should have known this as I know that pairing even an alkaline with a on-alkaline is NOT recommended. My apologies to everyone out there who has read my former comment. And a BIG THANKS to RbwNY for the help and advice!!!
