Welch Ally Batt99

Welch Allyn BATT99-Compatible Battery Overview

This high-capacity 9‑cell lithium‑ion pack (10.8 V, 7,500 mAh, 81 Wh) is designed for monitors and ECGs that call for the Welch Allyn BATT99. It delivers dependable power for mobile care workflows and helps minimize downtime in vitals capture and ECG acquisition.

Device Compatibility

• Connex Vital Signs Monitor 6000 Series
• Connex Spot Monitors: 7100, 7300, 7400, 7500
• CP 150 Electrocardiograph (ECG)

Tip: Always verify the battery model specified on the device label or in the user manual. If your unit references a different battery code, choose that model instead.

Runtime Planning

Runtime depends on device power draw and settings (e.g., NIBP frequency, SpO₂ use, Wi‑Fi, screen brightness). Use this quick estimate:

• Estimated hours ≈ 81 Wh ÷ device power (W)
• Examples: 6 W ≈ 13.5 h; 10 W ≈ 8.1 h; 15 W ≈ 5.4 h

For long shifts or transport workflows, keep a charged spare on hand to avoid gaps in monitoring.

When to Choose This Battery

• Use if your monitor or ECG explicitly lists “BATT99.”
• Choose for extended cordless use in rounding, triage, and mobile screening carts.

Consider Alternatives

• If your device is an earlier Vital Signs Monitor (e.g., 300 Series) or a different Welch Allyn model that specifies another battery code.
• If you need hot‑swap capability not supported by your device; check the device manual.

Installation (Typical)

1. Power down the device and disconnect external power.
2. Open the battery compartment and remove the old pack by its tab or release.
3. Insert the new pack fully until it seats; ensure contacts are clean and aligned.
4. Close the door, connect AC, and charge to 100% before first use.

Note: Procedures vary by model. Follow the device’s instructions for any required battery door screws or latches.

Care, Storage, and Safety

• Charge regularly; avoid deep discharges below ~10% when possible.
• For storage over 1 month: store at 40–60% charge in a cool, dry place (59–77°F / 15–25°C). Recharge every 3 months.
• Use only the device’s approved charger/power supply.
• Keep contacts clean and dry; wipe with isopropyl alcohol if needed.
• Do not crush, puncture, or expose to heat; replace any swollen or damaged pack immediately.
• Recycle through approved e‑waste or battery programs; follow local and lithium‑ion shipping regulations.

Troubleshooting

• Device won’t power on: confirm battery is fully seated and charged; try AC power to rule out charger/pack issues.
• Short runtime: reduce screen brightness/Wi‑Fi, check for continuous SpO₂, and fully charge; replace if capacity remains low.
• Intermittent power: inspect contacts and battery door; clean and reseat.

FAQ

How long does a full charge last?

It varies by device and settings. Use 81 Wh ÷ device power draw as a planning guide (e.g., 10 W ≈ ~8 hours). Continuous accessories and frequent NIBP cycles reduce runtime.

Do I need to calibrate the battery?

Not typically. For more accurate fuel‑gauge readings, perform a full charge and occasional full discharge/charge cycles as recommended by your device manual.

Can I use the device on AC while the battery is installed?

Yes, most compatible models operate on AC and charge the battery simultaneously. Refer to the device manual for behavior specific to your model.

When should I replace the battery?

Replace if runtime drops significantly, the pack shows damage/swelling, or the device reports a battery fault.

Is this an OEM battery?

Select this pack for devices that specify the BATT99 form factor. Always confirm compatibility with your device documentation.
