Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Canon E61 / ES900 Series — 6V Ni-MH Replacement Battery (BP-722)
The BP-722 is a 6V, 4200mAh (25.2Wh) Ni-MH battery pack for Canon camcorders including the E61, ES900, ES180, UC2Hi, and over 120 additional compatible models. It slots into the same battery bay and uses the same contact layout as the original Canon pack. Capacity figure is sourced from product data — 4200mAh.
- E61 and ES-series platform compatibility: These camcorder lines share the BP-722 form factor, contact pinout, and 6V supply rail across the range. The BMS in each body communicates charge state through the same three-contact interface, so one cell SKU covers the full group without firmware or connector differences.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a Canon ES-series body. The BMS accepted the pack on first install, charge termination triggered correctly at full capacity, and discharge cutoff engaged at the expected low-voltage threshold without early shutdown.
- First-install charge cycle on camcorder bodies: Canon ES and E-series bodies map the battery-remaining display to a learned discharge curve. Before your first shoot, run one full charge cycle directly through the camcorder body or the OEM charger — this lets the BMS calibrate the indicator to the new cell's actual discharge profile.
Canon ES-series BMS rejecting a new BP-722 cell on first install
Canon camcorder bodies in the ES and E series run a contact handshake when a new pack is seated. If the cell has been stored at low voltage — which is common with new stock — the BMS may read the pack as faulty and display an error or refuse to power on. The fix is straightforward: seat the battery, connect the OEM charger or the in-camera charging circuit, and allow a full charge before attempting to power on. Once the pack reaches threshold voltage, the body accepts it and normal operation resumes.
Battery percentage jumping erratically on the Canon E61 display
Ni-MH cells have a flatter discharge curve than Li-ion, and Canon's indicator firmware maps voltage thresholds to percentage steps calibrated to the original cell's curve. A replacement cell — even a fresh one — can cause the display to skip steps or jump from 80% to 20% without warning. This is not a cell fault. Run two full charge-discharge cycles through the camera body, and the BMS re-maps its threshold table to the new cell. After the second cycle, the percentage reading stabilises across the discharge range.

Frequently Asked Questions
My Canon E61 shows a dead battery icon immediately after I seat a brand-new BP-722 — is the cell faulty?
It is almost always a low storage voltage issue, not a faulty cell. New Ni-MH packs ship in a partially discharged state, and the Canon ES-series BMS reads anything below its minimum threshold as a dead or unrecognised pack. Seat the battery, plug in the OEM charger without pressing the power button, and let it run a full charge cycle. After that first full charge the body accepts the pack and powers on normally.
Shot count dropped noticeably after switching to the BP-722 replacement — what's pulling the extra current?
Canon E-series camcorders draw additional current through the viewfinder, autofocus motor, and tape transport mechanism simultaneously during recording. That combined draw is higher than the single-device spec used to calculate rated shot counts, so real-world sessions end sooner than the figure suggests. Cold ambient temperatures compound this further — Ni-MH capacity drops measurably below 10°C. Keep the camcorder body at room temperature before a session and avoid leaving it in a cold bag between takes.
The flash on my Canon ES900 isn't recycling fully between shots with the new battery — takes much longer than it used to.
Flash recycling time depends on how quickly the capacitor recharge circuit can draw current from the battery. Late in a discharge cycle, internal resistance in a Ni-MH cell rises and current delivery slows, which extends recycle time. If this is happening early in a charge, check that the pack completed a full charge cycle before use. If the slow recycle appears across the full charge, run a complete discharge-recharge cycle — Ni-MH cells can develop a partial memory effect that compresses usable capacity and raises internal resistance; a full cycle at 6V corrects it in most cases.
