What if your battery doesn’t work when connected to the device?
1. Test the OCV(Open Circuit Voltage). You can use the multi-meter to test the voltage. Standard voltage should be no less than 3.6V. If your battery is lower than 3.6V, please tell us.
2. Test loading voltage. The loading voltage should be around 3.2V. If your loading voltage is higher than 3.2V, the battery is in good condition. Due to the passivation characteristic of lithium thionyl chloride, your loading voltage may not reach 3.2V immediately. You can connect the battery with a resistor and activate it with a multimeter. When the loading voltage of the battery reaches 3.2V, then the activation is successful and the battery can be used.
3. If the battery fails to activate or is still unusable after activation, please tell us for help.
Warning:
1. Thoroughly read the product datasheet before use, inaccurate handling may cause leakage, heat, smoke, explosion, or fire, causing device trouble or injury.
2. DO NOT recharge, short-circuit, puncture, disassemble, deform, heat, incinerate, or place the battery near a direct flame. This battery contains flammable materials such as lithium and organic solvent and performing any of the above actions could cause it to ignite explode or become damaged.
3. DO NOT over-discharge, do not force discharge. In case the battery is over-discharged battery has potential of explosion. In case battery is over discharged, when connected with exterior power source or connected with other batteries in series, explosion may occur.
4. Keep this battery out of the reach of children. If it is swallowed, contact a physician immediately.
5. When storing a battery or throwing it away, be sure to cover it with tape. If the battery is contacted with other metal objects, it could cause fire or become damaged.
6. Insert the battery with the “+” and “-” ends correctly oriented.
7. Do not mix use old, new or different brand or type of battery.
8. Do not solder the battery directly.
9. Avoid storing the battery in direct sunlight, or in excessively hot and humid place.

It is what it is
Showed up on time and worked. Donât really know what else to say.

Batteries arrive almost dead!
I purchased a 10 pack of batteries and put them in my window sensors. The light on the sensors lit up once and then the batteries were dead. I tried them in different sensors, to make sure it wasn’t a bad sensor, but it happened in multiple sensors. I couldn’t find an expiration date on the batteries, I only found what can be seen in the attached image. DO NOT BUY!

Delivering the claimed power
If you carefully read the listing, youâll notice that the seller is quite transparent about the size and storage process for this type of battery. Itâs important to pay attention to these details, as the images can sometimes be misleading, making the battery appear similar to others. Make sure you confirm that this battery is compatible with your specific requirements before purchasing.I personally use this battery for a few sensors, and Iâve found that the device recommendations often prefer non-rechargeable batteries over rechargeable ones. This might be due to the fact that rechargeable batteries sometimes donât deliver the voltage they claim. In any case, this battery worked perfectly with my device, delivering the right amount of power without any issues.Price-wise, it was competitive when I made the selection, which was a bonus. The outer shell feels durable and of high quality, and the terminals are clearly marked, which is helpful when connecting it to the device. Overall, Iâm pleased with its performance and would recommend paying close attention to the product details if youâre considering this battery for your needs.

Passivation issues
Almost all 20 batteries did not work out of the box. The seller notes that this could be due to passivation but have poor instructions on how to deal with it. I emailed the seller and did not get a response. After loading the batteries with a 20 mA draw, I was able to get about half of them working. Still uncertain if they will last.

My battery powered Christmas LED string lights shine again
I can see on the label that the batteries are 1200 mAh and beneath I see a code that I assume is a lot number: EH6016. I also read on the label that they are type ER14250 and the size is 1/2 AA, providing 3.6 volts. I couldn’t find any shelf life or expiration date on the battery though. I got plenty of AAA batteries but I ran out of AA batteries for the LED string lights of my 2 small artificial Christmas trees. Even though on the back it says to use two AA batteries with 1.5 volts, I inserted four 1/2 AA batteries to replace two alkaline AA batteries to save time. I stacked two ER14250 batteries together to replace each AA battery and I checked that I aligned the positive and negative terminals correctly. Despite the higher voltage, the LED lights didn’t get destroyed and shine brightly whenever I turn them on.In a forum I learned that modern LEDs are quite robust and can handle a range of voltages without being damaged, as long as the current is within safe limits. The higher voltage from the ER14250 batteries might even make the LEDs brighter without causing any harm. I have the same experience. I tested the batteries with all my LED string lights and they work. As these are lithium batteries, I hope they will last longer than the original ones for this Christmas.

Affordable and reliable power solution for dog collars
I ordered these EEMB ER14250 10-pack 1/2 AA 3.6V Lithium Batteries to power my dog collar, and they have been performing reliably. These lithium batteries offer a decent 1200mAh capacity, which has kept the collar going for a good amount of time without needing frequent replacements. These batteries are compatible with several other devices I own as well. The steady voltage provided by these batteries helps ensure the performance of the dog collar remains consistent. This is particularly important when it comes to safety and effective use. So far, I havenât noticed any sudden drops in power or performance issues. The 10-pack is a good value for the price, especially if you’re someone who uses these batteries regularly for devices like dog collars or other small electronics. If you’re looking for a dependable battery to keep your petâs collar functioning smoothly, I highly recommend these EEMB batteries. they are a solid choice.

It’s cheeper
Works but not like major brands dies way sooner, granted you get what you pay for but they have 50% power life so pay little and get little or pay the price and get extended life. IMHO id rather pay price up front then running to devices changing batteries more often, still a good buy if your device barley consumers power or had standby

I purchased these to go with a digital thermometer. They didn’t work and i ended up purchasing better quality ones from the devices manufacturer

Dit is mijn tweede review. Ik ben benaderd door de leverancier. Kreeg gratis nieuwe. Die zijn een stuk beter (zie laatste afbeelding). Wanneer ik een SAFT erin doe, dan is het 100%. Laten we het erop houden dat ik een slechte batch had. Je kan ze met een gerust hart kopen. De leverancier help erg goed bij problemen. En de prijs is natuurlijk laag. (Hierna mij oude review) Waar andere merken 100% aangeven doet deze maar 30% na korte piek van 70. En twee dagen later nog maar 20%. Andere uit het doosje geprobeerd, 45%Niet best dus voor die prijs.

Die Batterien sind super. Waren alle voll und passen perfekt.

Considering the number of reviews stating they received batteries with low charge I was expectant that I would receive a similar item.It is my good fortune to be able to say that the new battery was inserted into the Eve door sensor and the Eve control app, which was showing 0% charge with the old battery, reported that the battery charge was now at 100%.About longevity; I will report back when I need another which will hopefully be another 12-18 months.
