The Verdict
If your Plantronics or Poly office headset has started dying mid-call, the problem isn’t the headset — it’s the battery. The BAOBIAN 2.4V Ni-MH replacement for BT162342/BT262342 is the fix you’re looking for, and with a 4.7-star average across 235 ratings, it’s clearly working for others too.
What You Actually Get
The package contains a single pre-assembled battery pack with the connector already attached. No tools, no adapters, no instructions — just the battery itself. The unit matches the OEM dimensions precisely, which matters because these headsets have tight battery compartments. The connector clicks into place on the first try, and the polarity is correct out of the box.
Real-World Performance
This is a Ni-MH battery, not lithium-ion, which is exactly what these headsets are designed for. The 2.4V output holds steady through the discharge cycle, which means your headset won’t start cutting out as the battery drains. In typical office use — a few hours of calls per day — you’ll get the same talk time as the original battery delivered when new.
One thing that stands out is the charge retention. Ni-MH batteries self-discharge, but this one holds its charge noticeably better than generic replacements. If you leave it on the charger base overnight and don’t use it heavily the next day, it’s still ready for a full day of calls.
What Buyers Consistently Praise
The reviews tell a consistent story. One verified buyer noted, “Exact fit, works perfectly. My headset lasted another two years after swapping this in.” Another mentioned, “Better than the OEM battery that came with the headset. Charges faster and holds longer.”
The most common theme across positive reviews is the fit. Several buyers mentioned trying cheaper alternatives that didn’t seat properly, causing intermittent connection issues. The BAOBIAN’s precise connector alignment eliminates that problem entirely.
Where It Falls Short
Let’s be honest about the limitations. First, there’s no documentation in the box. If you’ve never opened a headset before, you’ll need to look up a teardown video. It’s not difficult — usually two screws and a snap-open case — but it’s worth knowing before you buy.
Second, this is a replacement battery, not an upgrade. The capacity is comparable to OEM specs, so if your headset only gave you two hours of talk time when new, that’s what you’ll get here. Don’t expect miracles.
Third, the price point is slightly higher than no-name generic batteries. You’re paying a small premium for the reliable fit and consistent quality, and based on the reviews, it’s worth it.
Who Should Buy This
This is for anyone with a Plantronics or Poly BT162342, BT262342, BT183342, BT283342, or BT166342 headset whose battery has degraded. If your headset is otherwise functional and you don’t want to drop $100+ on a new unit, this $15-20 battery is the smart move.
It’s also ideal for offices with multiple headsets — buy a few and have them on hand, since battery degradation is inevitable and having spares saves you from downtime.
FAQ
Q: Will this battery work with my Plantronics Voyager 5200 or other newer models?
A: No. This is specifically for the BT162342/BT262342 battery format used in older Plantronics and Poly office headsets. Check your headset model against the compatibility list before ordering.
Q: How do I know when the battery needs replacing?
A: The signs are unmistakable — talk time drops significantly, the headset dies suddenly even when the indicator shows a charge, or the battery physically swells. If you’re seeing any of these, it’s time to swap.
Q: Can I use a higher-capacity lithium battery instead?
A: Don’t. These headsets are engineered for Ni-MH chemistry and the charging circuit expects it. Lithium batteries can overheat or damage the charging system. Stick with the correct replacement.
The Verdict
Rating: 4.6/5
Buy it if: You own one of the compatible Plantronics/Poly headsets and want a reliable, drop-in replacement that restores full performance without the cost of a new headset.
Skip it if: Your headset has other issues beyond battery life — physical damage, audio problems, or charging port failure. A new battery won’t fix those, and you’re better off replacing the headset entirely.
For what it is — a no-frills, correctly-built replacement battery — this is exactly what you need. It fits, it works, and it lasts. That’s all you can ask for from a consumable part.
