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.

Pure Clean PUCRCX70 — 9.6V LiFePO4 Replacement Battery (GZNF18730HP-3S1P)
This is a 9.6V LiFePO4 replacement battery rated at 1800mAh (17.28Wh) for the Pure Clean PUCRCX70 cordless vacuum cleaner. It replaces OEM part GZNF18730HP-3S1P and restores motor power for floor cleaning and debris collection. LiFePO4 chemistry holds voltage more consistently across a discharge cycle than standard Li-ion.
- PUCRCX70 fit: This battery matches the 9.6V rail and 3S1P cell configuration the PUCRCX70 motor controller expects. The BMS handshake and connector footprint are specific to this model — do not assume other Pure Clean vacuums share this pack.
- Bench tested on actual hardware: We ran this cell under sustained motor load and confirmed the BMS holds within spec. The protection circuit trips correctly on overcurrent and resets without requiring a manual power cycle.
- Dock charging on the PUCRCX70: Do not leave this vacuum on the charging dock permanently. Continuous dock charging on LiFePO4 cells accelerates capacity fade. Charge fully, then remove from the dock and store the vacuum off the charger.
Suction dropping before the battery indicator reaches low
On the PUCRCX70, suction loss mid-session is rarely a dead battery — it is usually motor voltage sag caused by restricted airflow forcing the motor to draw beyond its rated current. A clogged filter is the most common trigger. When airflow is blocked, the motor works harder, pulls more current, and the BMS may reduce output to protect the cell. Clean or replace the filter first, then retest before concluding the battery is at fault.
Motor cuts out on carpet and then recovers after a few seconds
This is a BMS overcurrent trip, not a battery failure. When the vacuum transitions from hard floor to thick carpet, the motor load spikes sharply. If the filter is partially blocked, that spike exceeds the BMS current threshold and the protection circuit shuts output to protect the cell. The pack resets after a short thermal recovery window — usually a few seconds. Clear the filter, check the brushroll for hair wrap, and confirm the pack voltage reads above 9.0V after a full charge.

Frequently Asked Questions
My PUCRCX70 loses suction halfway through a session even though the battery indicator still shows charged — what's happening?
A restricted filter forces the motor to draw more current than rated, which causes the BMS to reduce output before the battery is actually depleted. The indicator reflects cell voltage, not airflow efficiency — so the two don't track together. Remove and clean the filter, then retest on a hard floor with no obstructions. If suction holds after that, the filter was the cause, not the battery.
The vacuum motor shuts off on its own and then starts working again after I set it down for a few seconds — is the battery faulty?
That is a BMS overcurrent trip, not a defective cell. The motor current spikes when it hits carpet resistance or a partial blockage, and the protection circuit cuts output to prevent cell damage. It resets once the load clears. Check the brushroll for hair tangles and confirm the filter is clean — both will push motor draw above the BMS threshold and trigger this cutout pattern.
The replacement battery charges fully but the vacuum runs noticeably shorter than it used to on the original pack — what causes that?
If the original battery spent long periods sitting on the dock, its capacity faded from continuous trickle charging — and the new pack is now showing you what the vacuum actually draws at full health. A partially blocked filter compounds this: restricted airflow makes the motor work harder, increasing current draw and depleting the cell faster than the rated capacity suggests. Clean the filter and remove this pack from the dock once fully charged. Check resting voltage after a full charge — it should read at or above 9.6V.
