This is an uncommon battery item required primarily for special electronic equipment that calls for a size AA battery that produces 3.6 volts instead of the much more common 1.5 volt size AA batteries. It is also unusual in that it involves a battery chemistry using lithium ions. While I have had my pack of 4 batteries for only a month, so far the one I am currently using is doing exactly what I need and I am hoping each battery lasts for several months before a replacement is needed, but obviously that depends on how much power your instrument draws from the battery. I doubt it would be wise to use a 3.6 volt size AA battery in place of your 1.5 v AA flashlight batteries, and I suggest you don't try that. These are not rechargeable, so you'll have to discard the old one when it no longer works. That brings up a question for which I currently have no answer - can the batteries be discarded the same as common AA 1.5 volt batteries, namely in standard landfill garbage? The 3.6 volt batteries do not mention disposal issues so it probably would be best to ask your area representatives in charge of electronic items disposal if you can simply treat them like standard AA batteries, or if they have a special place you can drop off lithium batteries for recycling or special disposal. I found no supplier of the 3.6 v lithium batteries in my community but if you can find a local source of them, those folks might have an answer for you on appropriate disposal.

They hold a charge well and work reliably in the devices they’re designed for. No complaints about performance. One important thing to note: even though they are similar in size to AA batteries, they are NOT the same. Make sure your device specifically requires 3.6 V batteries before buying. Using them in place of standard AAs could damage your device. As long as you’re buying them for the correct application, they’re a solid choice.

Brand new, right out of the box, these batteries cause my charger to be in a constant state of reset on any given of the 4 charge slots. After letting them charge overnight, none have reached a full state. None are exceeding 4v during bulk charge. From this behavior, I wouldn't trust putting these in any of my devices. Also, all 4 batteries are behaving exactly the same way. When I put any of my 18650 or 16650 batteries in the same charger, they charge up just fine, no charger resets, bulk charge voltage as expected. There is something wrong with all 4 of these batteries, no doubt about it

Great

Battery went to a fair status after a couple weeks. Used for 6 weeks and went dead. Used it for my oil gauge. Now I am unable to return. Found out others had the same issue.

I didn't even know these existed. Used them in place of my custom, soldered 123 batteries, on electric fly swatters. They fit perfectly, last a lot longer and give an extra zap when I swat hornets.

I bought a 4-pack on 11/23 and it lasted almost a year with fairly heavy diving. About a year later I started getting intermittent low battery warnings on a liveabooard, doing 4 dives/day for 4 days in a row. I swapped it then. But took the old battery home. After a week or so of storage the "old" battery it was still testing pretty good. These are funny devices. They store a lot of energy, but they have high internal resistance so they deliver it slowly. Store unused batteries in the freezer until needed. (warm them back up to room temp before use) They claim a 10 year shelf life, but I'm skeptical. Better to not buy more than you can use in a few years. (I have a 5 year old SAFT cell that was never installed but was stored at room temperature and it shows very high internal resistance now) That's not a criticism of this mfg or SAFT. It's inherent to this type of battery chemistry.

3 of 4 batteries were dead out of the box. The 4th had a half charge. Very disappointing and unfortunately I've missed the return window. To pay this much for 4 batteries and receive them DOA is unacceptable and very poor QA. I would caution anyone else buying these to check them immediately.

produit conforme a la description, piles de remplacement pour mes thermostats font leur job

Buen material y muy rápido la entrega

Fanno il loro, prezzo interessante e compatibili con mio allarme. Arrivate in comoda confezione porta batterie da 4 posti.

Alles super

Es una pila muy poco convencional, no se suele usar en electrodomésticos comunes. Precio mas que competitivo. En comparación con otras pilas de las mismas características el precio es muy bueno y la calidad y duración mas que buena. Son una muy buena opción.
