Welch Allyn 72600

Welch Allyn 72600 Rechargeable Battery (2.5 V NiCd)

The 72600 is a 2.5 V nickel-cadmium (NiCd) rechargeable battery pack for Welch Allyn PocketScope rechargeable handles. It provides stable power for otoscope and ophthalmoscope exams in clinics, urgent care, and mobile settings.

Key specs

• Voltage: 2.5 V
• Chemistry: Nickel-cadmium (NiCd), rechargeable
• Capacity: ~600 mAh (typical)
• Form factor: PocketScope rechargeable handle pack (drop-in)
• Runtime: About 30–60 minutes of continuous illumination per charge (halogen heads); longer with efficient LED heads and intermittent use

Compatibility

• Works with: Welch Allyn PocketScope rechargeable handles rated 2.5 V.
• Does not fit: 3.5 V Welch Allyn handles, MacroView/other 3.5 V systems, or AA battery-only PocketScope handles.
• How to confirm: Check the handle’s label for “2.5 V” and a rechargeable cap/end. If the handle takes loose AA cells, this pack is not compatible.

When to choose it

• Choose if you use a 2.5 V PocketScope rechargeable handle and want predictable light output for frequent exams.
• Avoid if you use 3.5 V heads/handles or prefer disposable AAs (consider an AA PocketScope handle instead).

Installation (2–3 minutes)

1. Power off and remove the instrument head.
2. Unscrew the handle cap and remove the old pack.
3. Insert the 72600 with correct polarity (match the +/− in the handle).
4. Reinstall the cap and instrument head; test the light.

Charging and care

• Use a Welch Allyn-compatible charger for 2.5 V PocketScope handles.
• Initial charge: 12–16 hours. Typical top-off: 4–6 hours, or per charger indicators.
• For best results: Avoid deep discharging; recharge after use. Perform a full discharge/charge cycle about once a month to reduce NiCd memory effects.
• Storage: Cool, dry location; store around 40–60% charge if idle for >1 month.
• Contact care: Wipe contacts occasionally with a dry lint-free cloth to maintain reliable connection.

Safety and disposal

• NiCd contains cadmium. Recycle through approved battery recycling programs; do not discard in regular trash or incinerate.
• Do not open, crush, or short-circuit the pack. Keep away from heat and flames.
• Follow local regulations for transport and disposal.

Alternatives

• AA battery PocketScope handle (alkaline or lithium AAs) if you prefer disposable power.
• Upgrading to LED heads can extend runtime on the same battery due to lower draw.
• Welch Allyn 3.5 V systems for brighter illumination and longer runtime (requires different handle and battery).

FAQ

How long does the 72600 last per charge?

About 30–60 minutes of continuous use with halogen heads. Intermittent clinical use typically supports dozens of quick exams per charge.

How often should I replace it?

NiCd packs commonly provide hundreds of cycles. Replace when runtime noticeably shortens or charging becomes inconsistent, often after 1–3 years of routine clinic use.

Can I charge it in any Welch Allyn charger?

Use a Welch Allyn charger designed for 2.5 V PocketScope rechargeable handles. Do not charge in chargers meant only for 3.5 V handles.

Is it compatible with 3.5 V otoscope/ophthalmoscope heads?

No. The 72600 is for 2.5 V PocketScope rechargeable handles only. 3.5 V systems need their own handle and battery.

How can I tell if my handle uses this battery?

Look for a “2.5 V” marking and a rechargeable end-cap. If your handle accepts two AA cells directly, it does not use the 72600.
