When you need a replacement battery, you will often see two choices: OEM batteries and generic aftermarket batteries. In most cases, an original OEM battery is the better choice because it is designed specifically for your phone’s fit, charging system, and safety requirements.

Why generic batteries can be risky
Some generic batteries exaggerate capacity claims, use lower-quality cells, or have inconsistent fitment. While not every aftermarket battery is bad, it is much harder to know what you are getting. That is why many Canadians prefer buying from a trusted store that clearly identifies whether the battery is OEM.
