How to Install the Battery (Step-by-Step)
- Power down your OTDR and remove any cables or modules.
- Locate the battery compartment (usually at bottom or back).
- Release the latches or screws securing the old battery.
- Slide out the old battery pack carefully.
- Insert your new VIAVI 21175906 battery in the same orientation.
- Secure latches or screws as before.
- Power on the unit and confirm battery detection (check instrument display).
- Fully charge before first use (for optimal battery conditioning).
Tips for Maximum Battery Life & Safety
- Always store and charge between 20 % and 80 % when possible (avoid full 0 % or 100 % long-term).
- Use only the approved charger that corresponds to 7.26 V Li-Ion packs.
- Avoid exposure to extreme heat (> 60 °C) or freezing (< –20 °C).
- Inspect the battery regularly for swelling or damage discontinue use if deformation is found.
- If storing long term, store at ~ 40 %–50 % state of charge in a cool, dry place.
- Avoid deep discharging below the safe cutoff (instrument should protect).
- Calibrate (balance) your OTDR’s battery gauge periodically if your instrument supports it.
Frequently Asked QuestionsÂ
Is this battery truly compatible with all VIAVI OTDR units?
This battery pack is designed to match the original 21175906 spec (7.26 V, 13.0 Ah) used in many JDSU / VIAVI OTDR models. However, there are multiple OTDR models and battery revisions over time. Before ordering, please confirm your current battery label (voltage, capacity, and part number). If your instrument uses a different voltage or battery format, this pack may not be compatible.
How many charge cycles can I expect from this battery?
Under typical Li-ion design parameters, you can expect 300–500 full charge/discharge cycles with a gradual capacity fade over time. If you operate under moderate conditions (keeping between ~20% and 80%, avoiding extreme temperature), you may achieve a longer useful life.
Can I charge this battery with my existing OTDR charger?
Yes as long as your existing charger is compatible with 7.26 V Li-ion batteries and delivers the appropriate voltage/current. Most original JDSU/VIAVI OTDR chargers will work fine. Do not attempt to charge with a charger rated for a different voltage or battery chemistry.
How should I store the battery when not in use?
Store at ~ 40%–50% state of charge, in a cool, dry environment (ideally 15 °C to 25 °C). Avoid storing at full charge or at extreme temperatures for extended periods. Remove it from the instrument if you’re not going to use the OTDR for months.
What if the battery doesn’t fit my OTDR or fails to power on?
First, double-check the label on your original battery to confirm it is a 7.26 V / 13.0 Ah / 21175906 part. If it still doesn’t fit or the instrument won’t power on, contact our support team with your OTDR model number, existing battery specs, and photos. We offer compatibility assistance and may arrange a return or exchange if the wrong unit was sent.
What safety features are included?
The viavi 21175906 battery comes with advanced safety features for peace of mind.
This battery integrates a battery management system (BMS) that provides protection against overcharging, overdischarge, short circuits, temperature extremes, and cell imbalance. These protections are crucial for safe operation in field conditions.
