At a glance

• Chemistry: Lithium‑ion
• Voltage: 3.5 V
• Capacity: 2100 mAh (nominal)
• Typical runtime: up to ~120 minutes per charge (varies by head type and brightness)
• Intended use: Replacement battery for the 71900 handle

Compatibility

• Works with: Welch Allyn 71900 3.5 V Lithium‑Ion Rechargeable Handle.
• Does not fit: 71910 or 71930 NiCd handles, 71000/71000‑A, or C‑cell battery handles.
• How to confirm: Check the model number printed on your handle near the collar or end cap. If it reads 71900, this battery is the intended replacement.

When to choose it

• Use if you own a 71900 handle and want lighter weight and longer runtime than older NiCd options.
• Good for high‑volume clinics, mobile care, or LED instrument heads where you need consistent brightness.
• Avoid if your handle is 71910/71930 or older; select the matching NiCd battery for those models or upgrade to a complete 71900 handle.

Runtime and performance

• LED heads typically provide the longest runtime; halogen heads may shorten runtime, especially at maximum brightness.
• Expect up to about 2 hours on a full charge; actual time varies with head type and usage pattern.
• Stable output helps maintain illumination for consistent exams.

Charging and care

• Charge only with Welch Allyn‑approved chargers/stands designed for the 71900 handle.
• Lithium‑ion has no memory effect—top off anytime. If storing over a month, leave ~30–50% charge.
• Environment: store in a cool, dry place; avoid heat, moisture, and direct sunlight.
• Cleaning: wipe with a mild, compatible disinfectant. Do not autoclave or immerse.
• End of life: recycle through approved battery recycling programs; do not discard in regular trash.

Alternatives and related items

• For 71910/71930 NiCd handles: use the matching NiCd battery (e.g., 72200/72300 series depending on handle).
• Upgrading from NiCd: consider purchasing the complete 71900 lithium‑ion handle; the 71960 battery alone will not convert a NiCd handle.

Specs

• Voltage: 3.5 V nominal
• Capacity: 2100 mAh
• Chemistry: Li‑ion (rechargeable)
• Operating temperature: approximately 32–104°F (0–40°C)
