Flat Top has a flat positive terminal, compatible with most modern devices (headlamps, flashlights, DIY packs).
Button Top has a raised positive terminal (like a standard AA battery), required for older devices and certain battery holders with spring-loaded contacts.
Nickel Tab comes with nickel strips pre-welded to the positive and negative terminals. This is ideal for DIY battery pack building – no soldering required, just spot welding or direct connection.

A: Yes. This battery is an excellent choice for emergency lights and backup lanterns. Its 2600mAh capacity provides long runtime during power outages, and its 5A discharge rate is sufficient for most emergency lighting requirements.
Q3: Is this battery suitable for my solar lights?
A: Yes. This battery is an excellent choice for solar-powered outdoor garden lights. Its 2600mAh capacity provides long runtime through the night, and its 5A discharge rate is more than sufficient for garden light power requirements.
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.

Bought for a headlight used in night fishing. Lasted over 10h. Consistent brightness. No performance drop. Very pleased.
Bought these for my EDC flashlight. 7.6A is plenty for a single LED — turbo mode works without stepping down. 2550mAh gives noticeably longer runtime than my old 2000mAh cells. EVE consistency is great — measured IR on 4 cells, all around 25mΩ. Great value.
Using at near 2.5A continuous in a LED array barely warm. Good quality. No complaints.
Used in LED camp light baby monitor battery hack all work perfectly. 2550mAh is a sweet spot. Will buy more.
One battery arrived with minor dent I worried but it tested fine. Just a packaging issue. Good otherwise.
