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.

Sencor SVC 7020 — 14.4V Ni-MH Replacement Battery
This is a 14.4V 1800mAh Ni-MH replacement battery for the Sencor SVC 7020 cordless stick vacuum. It slots into the original battery housing and powers the vacuum motor through full cleaning cycles. Order this when the original cell no longer holds a charge or suction noticeably drops before the indicator shows low.
- SVC 7020 fitment: The SVC 7020 runs a 14.4V motor rail with a Ni-MH cell pack. This replacement matches that voltage and uses the same connector orientation and pack dimensions — 99.74 × 43.03 × 29.13mm — so the housing closes without modification.
- Bench tested on actual hardware: We cycled this cell through repeated full-discharge and charge sequences on the SVC 7020. The BMS held charge cutoff correctly at full capacity and did not trip under normal motor-start draw.
- Dock charging on the SVC 7020: Remove the vacuum from the charging dock once the cell reaches full charge. Ni-MH cells in cordless vacuums left on continuous dock charge develop capacity fade faster than cells charged only when depleted — charge fully, then disconnect.
Suction dropping before the battery indicator reaches low on the SVC 7020
Ni-MH cells show a flat discharge curve — the indicator stays green while the cell voltage is already sagging under motor load. On the SVC 7020, this means suction weakens noticeably before any low-battery warning appears. A partially blocked filter makes this worse: restricted airflow forces the motor to draw more current, pulling the cell voltage down faster. If suction drops early, check and clear the filter first, then test again with a fresh battery.
Motor cuts out mid-clean then recovers after a few seconds
This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, full dust cup, or a rug fibre caught at the nozzle — the motor draws above the BMS threshold and the pack shuts off to protect the cells. After a few seconds the BMS resets and the vacuum powers back on. Clear the blockage and check that the dust cup is emptied. If the cut-out continues on an unblocked vacuum with a new cell, check that the cell voltage under load stays above 12V.

Frequently Asked Questions
My SVC 7020 loses suction halfway through cleaning but the battery light still shows full — why?
The Ni-MH cell voltage sags under motor load before the indicator registers low, so suction drops while the light still reads green. A restricted filter makes this worse — blocked airflow pushes motor current higher and accelerates the voltage drop. Clear the filter and empty the dust cup first. If suction still fades early with a new battery, the original cell has lost capacity and needs replacing.
The SVC 7020 motor cuts out for a few seconds during vacuuming, then restarts on its own — is the battery faulty?
That cut-and-recover pattern is a BMS overcurrent trip, not a failed cell. Restricted airflow — a blocked filter, full dust cup, or a fibre caught at the nozzle — causes the motor to draw above the BMS threshold, which shuts the pack off temporarily. Clear the blockage and the cut-outs usually stop. If the motor still trips on a clear nozzle, check that cell voltage under load does not drop below 12V.
I replaced the battery but the SVC 7020 won't charge — the dock light does nothing
Some Sencor chargers expect the cell pack to present a minimum voltage before the charge circuit activates. If a deeply discharged Ni-MH cell reads below roughly 9–10V, the charger may not initiate. Try connecting the battery directly to the vacuum and running the motor briefly to confirm the cell has some residual voltage — if the motor runs at all, reconnect to the dock. If the cell reads 0V with a multimeter, the cell is dead and the replacement unit itself should be exchanged.
