You will need rechargeable batteries for 9V application! If you think about it, you will find that there are a lot of 9V batteries in your home. Garage door openers and smoke detectors are the most common ones in our home, and they usually don’t need to be replaced from time to time. However, when the time comes, you will need a replacement right away, and the chances are, you don’t have them stocked at home! NiMH Rechargeable batteries are the only alternatives in the past, and they do solve some of the problems. However, if you really switch to the NiMH alternative, you will soon discover when you need to recharge them, their capacity becomes nearly half unless you use the very expansive, top of the line, and even those won’t last till the third year! I have been using 3.7V Li-ion rechargeable batteries on my wireless security cameras for years, and they still work very well. This is why when I decide to replace the 9V disposable batteries; I choose to go with the Li-ion option. Hixon has one of the highest capacity 9V Lithium in desertcart search (850mAh), so I decided to give it a try. The package arrived on time is neatly wrapped in plastic to avoid accidental short of the electrodes. It takes about 2 hours to fully charge them and then is good to be placed in the smoke detectors. So far I have no issues with these batteries, and the ultra high capacity should last me 2 to 3 years without worrying to replace them or recharge them. I think this Li-ion 9V will replace all other types in the near future. Remember, you want to look for higher capacity than the 230mAh or 600mAh (some of them say 5400mW) models, because it will save you a few times to claim high to change/charge the batteries！ ## Features - Standard 9V batteries-9v batteries,Charging is very fast,Capacity 850mAh,Max output current 2.3A,The 9v lithium battery cycle life can reach 2000 times.The energy of 1pc Hixon 9V battery can equal 710pcs 600mAh 9V alkaline batteries. - Safety & Top High Performance-9V Li-ion Batteries are built with smart protection and CE, RoHS, MSDS Certified, 100% brand new and high quality!

I have left them on for a few hours extra and detected no extra heat. So I think the charger or batteries are smart enough to stop charging. Lithium has a low self discharge so I don't see any benefit to leaving them plugged in after they're fully charged. **Q: What size are these batteries? Are they the same size as standard alkaline batteries?** A: Loring Chien , Electrical Engineer for 45 years & IEEE Sr. Life member Answered 2 years ago · Author has 39.4K answers and 75M answer views I presume you are asking about Alkaline chemistry batteries. Their capacity is maybe on the order of 400 mAh. Actual capacity depends on the current value and the temperature. At higher current values the capacity is always smaller. And of course it varies some by manufacturer. this manufacturer rates these as 850mAh ......? **Q: How long does it take to charge the batteries? Mine have been charging for 12 hours and still flashing red lights.** A: The 9V batteries come with an initial charge (although how full I do not know). I remember placing them in the charger overnight, so I can't speak to when exactly they reached a full charge? I would recommend that you unseat the batteries and then slowly re-seat them. I found that it worked best if I did so in a rocking motion: one edge in place and then rock forward until firmly seated. Perhaps they're not fully connected? Otherwise, contact Hixon customer service in the event you have a defective charger and they need to replace. **Q: Can the Charger be used to charge other types of 9volt rechargeable batteries?** A: Hi, Yes it is a basic charger for most 9 volt batteries ## Customer Reviews ### ⭐⭐⭐⭐⭐ Holds charge fine, 2 weeks and haven’t had to recharge.
