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.

Snom M65 — 3.7V Li-ion Replacement Battery (10000058)
This 3.7V, 1200mAh Li-ion battery replaces the OEM pack in the Snom M65 DECT cordless handset. It fits the M65 directly, using the same physical footprint of 53.00 × 34.00 × 5.70mm. Capacity is drawn from the product data — 4.44Wh total energy.
- M65 handset compatibility: The M65 uses a single-cell 3.7V Li-ion pack with a specific connector and form factor. This battery matches that voltage rail and physical slot, so no adapter or modification is needed.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the M65 platform. The protection circuit responded correctly to cutoff events and accepted charge from the base station without fault flags.
- First charge on the M65 base station: Seat the handset in the base immediately after fitting this battery and leave it for a full charge cycle before using the handset. Li-ion cells shipped in storage state benefit from a complete initial charge to calibrate the handset's fuel gauge accurately.
Why the M65 base station shows no charge indicator on a new battery
Li-ion cells lose voltage during storage and can arrive below the base station's charge acceptance threshold. The M65 base checks cell voltage before initiating a charge cycle. If the pack reads too low, the base may show no indicator light or appear to ignore the handset entirely. Placing the handset in the base for several minutes usually allows a trickle pre-charge to bring the cell above the threshold — after that, normal charging resumes.
Talk time noticeably shorter than original battery after replacement
A new Li-ion cell does not always deliver full rated capacity on the first cycle. The handset's internal gauge may also be misaligned after the battery swap, causing early low-battery warnings. Run two to three full charge-and-discharge cycles through normal use to allow the cell and gauge to settle. After the third cycle, check whether the handset reaches 3.0V at cutoff — if it does, the cell is performing to spec.

Frequently Asked Questions
My Snom M65 handset lost its pairing with the base after I swapped the battery — how do I get it back?
Removing the battery cuts all power to the handset, which can clear the DECT pairing stored in memory. The M65 does not automatically re-pair on power-up. Put the base into registration mode, then run the handset's subscription procedure from the menu — this re-establishes the encrypted DECT link. Once paired, the handset should register within 30 seconds and show signal bars.
The M65 handset drains completely overnight even when it's sitting in the base — what's causing that?
Overnight drain while docked almost always means the handset is not making a clean contact with the base charging pins. Check that the handset clicks fully into the cradle and that the charge pins on both the handset and base are free of dust or oxidation. A battery that reads 3.7V in the morning confirms the base charged it correctly. If the handset still drops to below 3.2V overnight after cleaning the contacts, inspect the base power adapter output.
The M65 drops calls and loses range after I fitted this battery — was the old battery the problem or is something else going on?
Range drops when the handset's transmit power sags under RF load, which happens when battery voltage falls. A cell that reads 3.7V at rest but dips sharply under the current draw of DECT transmission suggests the cell has not yet completed its first full cycle. Run two complete charge cycles before drawing conclusions. If range is still reduced after that, check that the battery contact tabs on the handset are not bent — poor contact raises internal resistance and causes the same voltage sag symptom.
