⚠ Important Safety Warnings
Improper handling or misuse of this lithium-ion battery can result in FIRE, EXPLOSION, or THERMAL RUNAWAY, causing personal injury, property damage, or death. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.
- Critical Warning: Never carry loose batteries in your pocket, purse, or bag. Loose batteries can come into contact with metal objects like keys or coins, causing a short circuit, which may result in severe burns, fire, or explosion. Always store or transport batteries in a protective case or box.
- Intended Use: This battery is designed for integration into protected battery packs with a Battery Management System (BMS) or Protection Circuit Board (PCB). It is not intended for standalone use or use in devices such as e-cigarettes or vaporizers.
-
What is Thermal Runaway?
- A dangerous chain reaction where heat generated by a failing battery causes it to overheat further, potentially leading to fire or explosion.
- Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
- Prevention: Use a smart charger, avoid physical damage, and store batteries in a cool, dry place.
- Storage & Transport: Always store batteries in protective cases or boxes to prevent accidental contact with metal objects. Never store loose batteries in pockets, purses, bags, or near conductive materials.
- Inspection: Do not use if the PVC wrapper, terminal insulator, or casing is damaged, dented, leaking, or bulging. These are signs of internal damage or instability, and continued use could result in failure, fire, or explosion.
- Charging: Use a smart charger designed specifically for lithium-ion batteries and ensure that the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
- Prohibited Activities: Do not short circuit, modify, puncture, crush, expose to liquids, or solder directly onto the battery (spot weld only).
- Emergency Response: If a cell shows signs of thermal runaway (smoke, swelling, hissing, or heat), stop use immediately and, if it can be done safely, move it to a non-flammable surface (e.g., concrete or sand) away from combustibles. Lithium-ion cell fires are Class B fires — use an ABC/dry-chemical extinguisher, or douse with large amounts of water to cool the cell and prevent spread. Do not rely on a small spray; thorough cooling is required, and cells can reignite from residual heat, so monitor the area afterward. (Class D extinguishers are for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.

Genuine Panasonic batteries!!!! IMR great service and fast shipping!!!!
Great P45B's
Definitely holds a charge longer than previous 18650s.
I have two (2) TESTERS. Both from LittoKala. On the Lii-500 it tested at 3375mah. On the Lii-M4S. it tested at 3633mah. VERY GOOD RATINGS. A couple of years ago I purchased thirty (30) 25R Samsung batteries from you. But as the price rose I bought some 35E and 30Q batteries from CHINA. The batteries clearly had SAMSUNG stamped on the battery. Neither group of batteries tested even 1/2 of the rated mah. That is why I purchased a 35E and a 30Q from you. The 35E tested at 3535mah and the 30Q at 3359mah. LESSON LEARNED. YOU GET WHAT YOU PAY FOR!!
I have a couple pair of these that are 6 years old and still going strong, IMR Is a great place for all your battery needs
saves so much money on new batteries!
It was the wrong battery! And I’m not allowed to return it i don’t believe!
Worked great
Exactly what I ordered
Replaced brand new generic batteries on a product I received with the Panasonic batteries. Battery lasts about 5x longer before needing recharge. Exactly what I was hoping for.
Looks like a battery, feels like a battery, works like a battery.
Batteries arrived fast, and fit perfectly. My UPS is now fully functional!
Thank You.
Loaded the 4 batteries for a UPS for a Raspberry Pi web server.
Batteries are great, 5 stars.... but apparently they will bug you non stop, this is a response to the 3rd or 4th email, until you leave a review so 1 star on customer experience. Hopefully now the emails will stop.
