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.

Schick F34 / F40 / WR5000 / WR7000 — 2.4V Ni-MH Replacement Battery
This is a 2.4V, 2000mAh Ni-MH replacement battery for Schick cordless electric shavers including the F34, F40, WR5000, and WR7000. The original cell degrades over repeated charge cycles, cutting cordless use time well before the low-battery indicator triggers. This cell restores full cordless operation at factory voltage and capacity.
- F34, F40, WR5000, WR7000 fit group: These models share the same 2.4V single-cell Ni-MH architecture, connector pitch, and physical envelope — 49 x 29 x 14.5mm. The BMS in each shaver expects the same charge termination behaviour that Ni-MH delivers via delta-V detection, so no handshake issues on swap.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the shaver platform. The BMS accepted charge termination cleanly and the motor held consistent speed across the full discharge curve until BMS cutoff.
- Wet shaver charging port rule: After rinsing the shaver head, let the unit air dry for at least 30 minutes before placing it in the charging dock. Moisture bridging the dock contacts causes a BMS protection trip that the shaver reports as a dead battery — not a charging error.
Motor speed dropping before the low-battery indicator activates
Ni-MH cells age by losing internal capacity while retaining surface charge — the shaver reads voltage as adequate but the cell can't sustain current under motor load. The motor draws a spike on each cutting stroke, and an aged cell can't hold voltage through that spike. Speed drops noticeably mid-shave while the indicator still shows partial charge. Replacing the cell resets this: a fresh 2000mAh cell holds voltage flat under load until genuine BMS cutoff.
Capacity fade from daily partial charging on these shavers
Many users dock the shaver overnight every night without depleting it first. Ni-MH cells develop a soft memory effect under repeated shallow cycling — the cell's effective capacity drifts down, and the indicator calibration drifts with it. The shaver appears to charge fully but cuts out earlier each week. To slow this on the new cell, run the shaver to BMS cutoff once every 4–6 weeks before recharging from flat.

Frequently Asked Questions
My Schick shaver loses motor speed halfway through a shave but the battery indicator still shows charge — what's happening?
This is voltage sag under motor load, not a faulty indicator. The aged Ni-MH cell holds enough surface charge to satisfy the voltage sensor at rest, but collapses under the current draw of the cutting motor. The indicator reads resting voltage, not load voltage — so the two readings diverge as the cell degrades. Replacing the cell is the fix; a fresh 2000mAh cell holds above 2.0V through the full discharge under load.
After I rinsed my shaver, it stopped taking a charge in the dock — is the battery dead or is something else wrong?
Water on the dock contacts is the most likely cause, not a failed battery. Moisture bridges the charging pins and triggers a BMS protection trip; the shaver then refuses to accept charge and can look completely dead. Remove the shaver from the dock, dry the charging contacts on both the shaver and the dock thoroughly with a dry cloth, and leave both to air dry for at least an hour. Place the shaver back in the dock — if charging resumes, the battery was fine; if the dock contacts have corroded, clean them with a dry cotton swab before reconnecting.
The shaver docking contacts look discoloured and charging is intermittent — is that a battery issue?
Discoloured dock contacts are oxidation from cleaning product or hard-water residue, not a battery fault. The oxidised contact layer increases resistance, so charge current to the cell is inconsistent — the shaver may show charging, then stop, then restart. Clean both the shaver base contacts and dock pins with a dry cotton swab; if oxidation is stubborn, use a swab lightly dampened with isopropyl alcohol and let it dry fully before docking. Once contact resistance drops back to near zero, normal charge current resumes and the battery charges as expected.
