JOXIYECLTL LIR2032 Rechargeable Battery 4-Pack with Charger – 3.7V 45mAh Lithium Button Cells Replace CR2032 ML2032 for Car Keys and More

This JOXIYECLTL 4-pack of LIR2032 rechargeable batteries delivers a steady 3.7V, 45mAh power source that can be recharged up to 500 times, offering a sustainable alternative to disposable CR2032 and ML2032 cells. The set includes a dedicated button charger that tops off each battery in roughly 2 hours. Ideal for car key fobs, glucometers, Bluetooth earphones, and other compact electronics that rely on 2032-sized lithium coin cells.

What makes the LIR2032 different from a CR2032?

The key difference is rechargeability. A standard CR2032 is a single-use lithium cell that must be discarded once depleted. The LIR2032, on the other hand, can be reused hundreds of times (up to 500 cycles according to manufacturer specs). This makes it a cost-effective and environmentally friendlier choice for devices that drain batteries quickly. The physical dimensions are the same, so it fits in the same compartments, but the voltage is slightly higher (3.7V vs 3V for CR2032). Always check your device's voltage tolerance; most devices designed for CR2032 can handle 3.7V, but some may not. That said, this LIR2032 is designed as a direct replacement for CR2032 and ML2032 in many applications.

Where can you use these rechargeable button cells?

These batteries are suited for any device that uses a standard 2032-sized coin cell and can accept a 3.7V input. Common uses from the included specs include Bluetooth earphones, small lights, game controllers, solar keyboards, car key remote batteries, and glucometers. They're especially handy for gadgets that go through disposable coin cells quickly, such as car key fobs and remote controls.

Specifications to know before buying

Charging and usage tips

The included button charger is designed specifically for these LIR2032 cells. Simply insert the battery into the slot and plug the charger into a USB power source. A full charge takes about 2 hours. The batteries hold their charge well when not in use, but like all rechargeables, they may self-discharge slowly over extended periods. For best results, store them at room temperature and avoid deep discharge.

Frequently asked questions

How many times can I recharge these batteries?

The manufacturer states they can be recharged up to 500 times. Actual lifespan depends on discharge depth and charging conditions.

Can I use these in a device meant for CR2032?

In most cases, yes. The LIR2032 has the same physical dimensions but a slightly higher voltage (3.7V vs 3.0V). Check your device's manual to confirm compatibility, especially for sensitive electronics.

Does the charger work with other battery types?

The charger is designed only for LIR2032 button cells. Do not use it for CR2032 or other chemistries.

What safety certifications do these batteries have?

They meet ISO9001, UL, CE, RoHS, and UN38.3 standards, indicating compliance with international safety and quality requirements.
