Kastar 4-Pack BP-809 7.4V 1500mAh Camera Batteries - Longer Runtime

Our review of the Kastar 4-Pack BP-809 batteries finds them best for videographers and casual users who need dependable spare power for older Canon VIXIA and FS series camcorders. The single biggest reason to buy is straightforward: these are high capacity replacement batteries that extend run time compared with many generic alternatives, and the 4-pack format keeps a camera running through long shoots without hunting for chargers. For anyone who relies on continuous recording or hates swapping packs mid-shoot, this set solves that pain point affordably.

Key Features

• High Capacity: Each 1500mAh cell provides noticeably longer runtime so a camera can record for extended sessions before swapping batteries.
• Correct Voltage: The 7.4V lithium-ion design matches the original power requirements so the packs work as direct replacements for compatible Canon models.
• Safety Protections: Built-in over-charge, over-discharge, over-voltage, over-current, and over-heating protection circuits reduce the risk of damage to the battery or camera during use.
• Standards Compliance: Cells meet UL1642 and CE safety standards, giving extra reassurance about manufacturing and safety practices compared with unknown generic cells.
• Value Pack: The package includes four batteries, which lowers per-battery cost and keeps spares on hand for longer shoots or travel without frequent recharging.

Who It's For

These replacement batteries suit owners of Canon BP-809 series and related models who need dependable backup power for events, family video, or field shoots and prefer buying multiple spares at once. Small production teams and hobbyists using Canon VIXIA HF M-series and older FS series camcorders will find the 4-pack especially practical.

Users seeking official manufacturer batteries for the latest camera models should look elsewhere; the Kastar pack is tailored to specific Canon BP-809/BP-819/BP-827 compatible camcorders and older chargers and is not a universal solution for modern camera lines.
