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

🔹 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.

Redmond RV-UR365 — 18V Li-ion Replacement Battery (INR18650-5)

This is an 18V 2000mAh Li-ion replacement battery for the Redmond RV-UR365 cordless handheld vacuum cleaner. It uses INR18650-5 cells and fits directly into the RV-UR365 battery compartment. Order this when the original pack no longer holds charge or the vacuum shuts off well before the indicator reaches low.

  • RV-UR365 fit: The RV-UR365 runs an 18V motor rail with a BMS that monitors cell voltage and current draw. This pack matches that voltage rail and connector, so the vacuum's motor controller reads the battery correctly on startup.
  • Bench tested on actual hardware: We cycled this pack through multiple charge and discharge runs on a vacuum motor load. The BMS held the cutoff voltage steady and did not trip under normal suction draw.
  • Dock charging on cordless vacuums: Do not leave the RV-UR365 sitting on the dock permanently. Cordless vacuums on continuous dock charge develop capacity fade significantly faster than those charged only when depleted. Charge to full and remove from the dock.

Suction dropping before the battery indicator shows low

The RV-UR365 motor draws more current when the filter is partially blocked or the suction path is restricted. That extra draw causes the cell voltage to sag under load, even when resting voltage still looks healthy. The BMS registers the sag and reduces output to protect the cells — suction drops noticeably. Check and clean the filter first; if suction restores, the battery was not the cause.

Motor cutting out mid-use and then recovering after a short pause

This is a BMS overcurrent trip, not a dead battery. Sustained restricted airflow — blocked filter, sealed nozzle, or heavy carpet load — pushes motor current above the BMS threshold. The BMS cuts power to protect the cells, then resets once current demand drops. Clear the restriction, then resume use. If the cutout happens repeatedly on open airflow, check that resting cell voltage is above 15V before ruling out the pack.

Frequently Asked Questions

The replacement battery charges fully but the vacuum loses suction halfway through cleaning — what's happening?

A partially blocked filter forces the motor to draw above its rated current, which causes cell voltage to sag under load even from a full charge. The BMS interprets that sag as low battery and reduces power to the motor. Clean the filter thoroughly and retest before assuming the pack is faulty. If suction stays strong after cleaning, the battery is fine.

My RV-UR365 keeps cutting out for a few seconds and then restarting on its own — is this the battery or the motor?

That's a BMS overcurrent trip, not a motor fault. The BMS cuts the output when current demand spikes — usually from a blockage at the nozzle or a clogged filter creating back-pressure on the motor. It resets automatically once current drops, which is why the vacuum restarts. Clear the nozzle and filter, then retest on a hard floor; if the cutout stops, the pack is working correctly.

The battery was fine initially but capacity seems to have dropped after a few weeks — I leave it on the dock when not in use.

Continuous dock charging is the most common cause of early capacity fade on cordless vacuums. The charger delivers a low-level trickle current while the pack sits on the dock, and repeated trickle cycles degrade Li-ion cells faster than regular charge-and-discharge cycles. Remove the battery from the dock once the charge indicator shows full. Going forward, only dock the vacuum when it actually needs charging.
