BP-820 Replacement Batteries with Dual Bay Charger - Reliable Power

In this review of the BP-820 replacement batteries and dual bay charger kit the bottom line is simple: it is aimed at videographers who need dependable, long runtime power for Canon Vixia and XA/XF camcorders. The kit pairs two 2000mAh BP-820 Li-ion cells with a travel-ready dual bay charger that can accept AC or 12-24V DC, so the most compelling reason to buy is uninterrupted shooting on location without hunting for a compatible charger. The reviewer found the new fully decoded chip and safety circuitry restore accurate battery level reporting and allow fast, memory-free charging.

Key Features

• Compatibility: Works with a long list of Canon Vixia, XA and XF camcorder models so you can replace OEM BP-820 packs without compatibility worries.
• Battery Capacity: Each battery delivers 2000mAh at 7.4V (about 14.8Wh), providing noticeably longer recording time than an aging original pack.
• Decoded Chip: The new fully decoded chip reports remaining run time like the original battery and does not require a special charger to display levels.
• Fast Dual Charging: The custom IC charger can charge one or two packs simultaneously and uses CurrentSmart and VoltageBoost to speed charging up to 1.5A when supported.
• Travel Ready: Worldwide AC 100-240V plus DC 12-24V car input makes the kit convenient for international and on-the-road use.
• Safety Design: Built-in protections for over-charge, short-circuit, high temperature and surge reduce the risk of failure in field use.

Who It's For

This kit is best for independent filmmakers, event shooters, and journalists who use Canon Vixia HF and XA/XF series camcorders and need dependable spare power and a flexible charger for travel or car use. It is particularly useful when a second battery is required for back-to-back events or long interviews.

Users who prioritize factory-branded accessories or who require OEM warranty-based service may prefer original manufacturer batteries; likewise, operators needing ultra-high-capacity aftermarket packs beyond the documented 2000mAh spec should look at specialty power solutions.

Pros & Cons

• Memory-free Li-ion chemistry allows topping up at any time without reducing capacity.

Cons

• At 2000mAh capacity, runtime is good but not higher than some specialty high-capacity aftermarket options.
