FAQ
Q1: What is the capacity of this battery?
A: This battery has a 3300mAh capacity (minimum 3200mAh), offering significantly longer runtime than standard 2600mAh batteries. This makes it ideal for devices that need to run for extended periods without recharging.
Q2: Is this battery suitable for my solar garden lights?
A: Yes. This battery is an excellent choice for solar-powered outdoor garden lights. Its 3300mAh capacity provides long runtime through the night, and its 10A discharge rate is more than sufficient for garden light power requirements.
Q3: What is the advantage of buying the 2-Pack?
A: The 2-Pack offers two main advantages: convenience and value. You get two matched cells in one package, saving time and effort. You also get better value compared to buying two single cells separately.
Q4: Is this battery protected or unprotected?
A: This is an unprotected cell. It relies on your device's built-in BMS (Battery Management System) or protection circuit to handle overcharge, over-discharge, and short-circuit protection. This provides maximum flexibility for use in devices with built-in protection.
Q5: What charger should I use?
A: Use a dedicated intelligent Li-Ion charger designed for 3.7V/4.2V cells. Do not use universal chargers designed for NiMH batteries. Look for chargers with overcharge protection and temperature monitoring features.
Q6: How should I store these batteries?
A: Store at a partial charge (around 40-60% capacity) in a cool, dry place away from direct sunlight and extreme temperatures. Do not store fully charged or fully depleted for extended periods.

Built a 1S3P pack with these for camping, lasts 3 nights. EVE 33V is reliable, voltage stays above 3V under load.
At 5A draw, voltage holds nice and flat. 10A max is safe for most home electronics. Good for remote controls too.
I use these in a USB power bank kit, they provide over 6000mAh at 5V. 10A allows fast charging. Flat top works.
Cells arrived at 3.5V, well packaged. Used in a portable fan, runs 8 hours. I'm satisfied.
Replaced all my AA NiMH with these EVE 33V and a small boost converter. 3300mAh runs lights all night. 10A is more than enough.
