Two-pack replacement batteries and dual charger

This Kastar kit supplies two 7.4 V lithium-ion cells rated at 2600 mAh and 19.24 Wh each, matching the Canon BP-511A form factor. They power a long list of EOS, PowerShot, Optura and ZR series cameras as well as several DM-FV and MV camcorders. The pack targets photographers and videographers who need spare capacity for extended shoots without relying on a single original battery.

LCD dual charger with interchangeable plates

The included LTD2 charger accepts 5 V input via Micro-USB or USB-C and can charge both batteries simultaneously at 800 mA per slot. An LCD panel shows real-time charging status and remaining capacity for each cell. Swappable plates let the same charger handle other compatible battery models, reducing the number of accessories required in a gear bag.

2600 mAh per cell for multi-hour sessions

Each battery delivers roughly 19 Wh, enough for several hundred still frames or multiple hours of video on supported Canon bodies. Two cells give a combined reserve that covers most day-long events, though continuous high-drain recording or cold-weather use will deplete them faster. Users needing all-day power without recharging should plan for additional packs.

Questions about this item

How many charge cycles can the 2600 mAh Li-Ion cells sustain before capacity drops below 80 %?

Each 7.4 V 2600 mAh pack is rated for roughly 300 to 500 full cycles; storing at 40–60 % charge and avoiding deep discharge extends usable life.

What thermal limit throttles the LTD2 charger during continuous dual-bay operation?

The 5 V 2–3 A input is capped at 15 W; sustained dual-bay charging at 8.4 V 800 mA per bay keeps the unit below its internal thermal cut-off.

How much heat and fan noise does the dual charger produce when running all day?

No fan is fitted; the 15 W input and 800 mA per bay output generate only modest warmth, leaving the charger silent during extended sessions.
