Axis 02725-001 TW1906 Battery Replacement Kit for W101, 5-Pack
Overview
The Axis 02725-001 is a five-pack of genuine Axis TW1906 replacement batteries engineered specifically for the Axis W101 wireless surveillance camera. These are not generic batteries — they're lithium thionyl chloride (Li-SOCl2) chemistry cells matched to the power profile and connector specifications of the W101 platform. If you're running W101 cameras in permanent or semi-permanent installations, managing battery stock is part of your operational cost. This kit gives you five units ready to swap when runtime drops, eliminating the delay of sourcing replacements mid-deployment.
Key Features
- Lithium Thionyl Chloride Chemistry: Li-SOCl2 cells deliver high energy density and exceptionally stable voltage output across the discharge cycle — important because the W101 needs consistent power to maintain frame rate and image quality. Unlike alkaline batteries, Li-SOCl2 cells don't sag under load, so your camera won't randomly drop frames or lose connectivity as the battery ages.
- Five-Unit Pack: One kit gives you enough spares to rotate batteries across multiple W101 cameras without gaps in coverage, or to stock replacements across multiple sites.
- OEM-Matched Design: These are purpose-built for the W101 connector and power draw, not generic off-the-shelf cells. Connector fit and polarity are guaranteed; no risk of inserting a battery backward or causing a short.
- Extended Shelf Life: Li-SOCl2 cells self-discharge at roughly 2–3% per year when stored unopened, so you can buy this kit and hold inventory without watching the batteries die on the shelf.
- No Thermal Management Risk: Lithium thionyl chloride operates safely across wide temperature ranges without the fire hazard of older lithium coin cells, making it suitable for outdoor and temperature-extreme W101 deployments.
- Axis Warranty Coverage: These batteries carry Axis's standard parts warranty, backed by manufacturer support for defects in materials and workmanship.
Integration & Compatibility
The Axis 02725-001 (often searched as 02725 001) is a direct replacement for the TW1906 battery specified in the W101 technical documentation. Before ordering, confirm your W101 model uses the TW1906 form factor — older or regional variants of the W101 may use different cells. If you manage a fleet of Axis wireless surveillance cameras, maintaining a central supply of approved batteries prevents the false economy of buying cheap Chinese cells that fail unpredictably in the field.
Deployment Considerations
Battery runtime on the W101 depends on video quality settings (resolution, frame rate, bitrate), IR use, and ambient temperature. Cold weather shortens Li-SOCl2 runtime by roughly 20–30% compared to room temperature. If your W101 cameras are mounted in unheated outdoor enclosures and you expect year-round operation, plan for shorter intervals between battery swaps in winter.
For high-density W101 deployments (5+ cameras per site), consider tracking battery swap dates in your preventive maintenance log. Unlike mains-powered cameras connected to network video recorders, wireless models with no backup power will simply go dark when the battery is exhausted — there's no graceful degradation.

Frequently Asked Questions
Q: How long does a TW1906 battery last in a W101 camera?
A: Runtime depends on video quality, IR usage, and temperature. Axis specifications typically cite 12–24 months under normal conditions, but high-bitrate streams or frequent IR operation will shorten that. Check your W101 setup guide for expected runtime under your specific configuration.
Q: Can I use non-Axis TW1906 batteries in my W101?
A: Technically, any compatible Li-SOCl2 cell with matching voltage and connector may work, but non-OEM batteries may have different internal resistance, self-discharge rates, or connector tolerances that cause intermittent power loss or camera resets. Axis recommends OEM batteries to ensure reliability.
Q: Is there a lead time for the 02725-001 kit?
A: Availability varies. Check with your distributor; genuine Axis parts typically ship within 2–5 business days if in stock.
Q: Do these batteries require any special disposal?
A: Lithium thionyl chloride cells are classified as hazardous materials in many regions and require special handling at end of life. Check local regulations and use a certified battery recycler; do not dispose of in standard waste streams.
Q: Can I extend battery life by adjusting W101 settings?
A: Yes. Lowering resolution, reducing frame rate, disabling continuous IR (switch to motion-triggered IR), and enabling compression all reduce power draw and extend runtime. Lower bitrate streams consume less battery than high-quality ones.
Q: Are these 02725-001 batteries compatible with any other Axis products?
A: The TW1906 is specific to the W101 line. Other Axis wireless or battery-backed products use different battery types. Always verify the part number against your device's documentation.

The Axis 02725-001 is a straightforward but essential commodity in any W101 deployment. You're buying OEM-matched lithium thionyl chloride cells with guaranteed connector fit and known discharge profiles — not a feature-rich device, but a mission-critical consumable. Li-SOCl2 chemistry is the right choice for wireless surveillance: it resists voltage sag under load, self-discharges slowly in storage, and handles temperature extremes better than alkaline alternatives.
Technical Highlights:
- Lithium Thionyl Chloride (Li-SOCl2): Stable voltage output across the discharge curve means the W101 maintains consistent frame rate and connectivity even as the battery ages — no brownout failures where frames drop unexpectedly near end-of-life.
- Five-Unit Pack: Covers battery rotation across 5 cameras or provides a 12–24 month supply for a single site, depending on usage. Bulk packing also reduces per-unit cost compared to single-battery purchases.
- Shelf Stability: 2–3% annual self-discharge allows you to stock this kit centrally without watching inventory evaporate. Compare to alkaline cells, which lose 15–20% per year sitting on a shelf.
Deployment Considerations:
- Cold-weather degradation is real: W101 runtime drops 20–30% in unheated outdoor enclosures during winter. If you have a fleet across multiple climates, expect shorter battery intervals at northern sites.
- No failover. Unlike mains-powered cameras, a dead W101 battery means instant loss of feed — no graceful degradation, no warning period. Build battery change intervals into your maintenance schedule, don't wait for alarms.
- Hazmat logistics: Li-SOCl2 cells are classified hazardous material for shipping and disposal in most jurisdictions. Plan your battery recycling pathway; don't let dead cells pile up in a drawer.
Use the 02725-001 kit for any production W101 deployment where battery redundancy matters — warehouse perimeter monitoring, temporary outdoor event coverage, or remote site surveillance without mains power. It's not glamorous, but it prevents the expensive field visit where your camera went dark because you ran out of spares.
