Quick take
This BAOBIAN rechargeable battery pack is built to replace common 2.4V NiMH (AAA x2) cordless phone batteries, including BT-18433/BT-28433 compatible models. It is a practical option if your handset is losing charge, with buyer feedback pointing to reliable runtime once fully charged. The main caveat is fit, especially confirming the connector type and matching the battery leads to your original pack.
Pros and cons
Pros
- Designed for 2.4V NiMH cordless phone battery packs, using AAA cells (AAA x2).
- Pack is listed as compatible with multiple AT&T/Lucent model numbers including BT-18433 and BT-28433 series.
- Protection features are included (over-voltage, over-current, over-charge, and short-circuit).
- Buyer reports emphasize improved charge holding and solid talk time after installation.
Cons
- Connector and plug type must match, otherwise you may not be able to seat it properly.
- Some buyers note the first full charge can take longer than expected.
- Third-party battery fit can vary slightly by model, so double-check lead length and orientation.
What buyers think
Buyer-review evidence is broadly positive but also includes a few practical setup and fit themes. Many mentions focus on restored performance on older AT&T/Lucent or similar cordless phones, with reports that the batteries hold a charge and provide sufficient talk time for day-to-day use. Several reviews also emphasize that letting the new pack charge fully, rather than starting immediately, helps the battery reach its expected capacity.
On the tradeoff side, feedback is most consistent around charging time during the first cycle and minor physical considerations such as how the connector seats or how the leads should be oriented. Buyer-review evidence is limited on long-term brand comparisons, so results may still depend on the exact handset model, charger behavior, and how the battery pack is installed.
What this battery is, and the key specs that matter
This is a rechargeable 2.4V cordless phone battery pack using NiMH cells in an AAA x2 configuration. Capacity is listed at 550mAh, and it is intended for use as a replacement battery for compatible cordless phone models.
Compatibility details to verify
- Model matching: It is listed as compatible with specific AT&T/Lucent series including BT-18433 and BT-28433 families, along with additional listed model numbers.
- Connector type and plug shape: The pack uses an EH plug and a square connector form factor, so you should confirm the connector on your original battery matches.
- Do not mix batteries: It is intended to be used as the correct 2.4V pack for your device, not paired with other 2.4V packs that do not match the exact type.
Who it’s best for
- Owners of older AT&T/Lucent cordless handsets that use BT-18433/BT-28433 style 2.4V NiMH battery packs.
- Buyers looking to revive talk time on a handset that has become unreliable as its original battery ages.
- People comfortable doing a basic battery swap and checking connector/lead orientation before closing the handset.
Who should skip it (or buy with extra caution)
- Anyone unsure about connector compatibility. If your current battery has a different plug type or shape, you risk a poor fit.
- Buyers who want instant “ready to go” performance. Some users report that the first charge cycle can take a while before the battery fully reaches capacity.
- Shoppers seeking an exact OEM match for very particular lead lengths or mechanical fit tolerances, since third-party packs can require reorientation to avoid overstretching the leads.
Pros and cons, translated into real buying decisions
Why buyers choose this pack
- Model-specific intent: The listing targets known cordless battery part families (not a generic phone battery).
- Safety-oriented design notes: Over-voltage, over-current, over-charge, and short-circuit protection are included, which supports everyday charging confidence.
- Practical performance feedback: Reviews commonly mention improved charge holding and usable talk time after installation.
What could make it a mismatch
- Connector and seating: If the connector style or plug geometry does not match your original battery, the battery may be difficult to seat correctly.
- First charge expectations: If you replace a battery and unplug too early, you may interpret normal initial charging delay as underperformance.
- Lead routing: Slight differences in lead placement can require careful orientation so the connector and wires rest correctly inside the compartment.
Alternatives to consider
If you are not fully confident about connector fit or you need a different battery specification, alternatives generally fall into two categories:
- Exact OEM replacement batteries for your handset model, if available. This reduces connector/fit uncertainty but may be more expensive.
- Other compatible third-party 2.4V NiMH packs, but only when the listing explicitly matches your battery part number family and connector type. If the connector details differ, compatibility claims may not translate to a clean physical install.
How to get the best results after installation
- Charge fully before heavy use: Give the handset time to reach a complete charge cycle according to your phone’s instructions.
- Check connector fit before closing: Ensure the plug seats securely and the leads can route without strain.
- Don’t mix battery packs: Use a matched pack for your device’s required 2.4V battery type.
Verdict
These 2.4V rechargeable NiMH cordless phone batteries are a solid replacement choice for buyers with compatible BT-18433/BT-28433 style cordless handsets. The main reason to pause is connector and physical fit verification, plus realistic expectations for the first full charging cycle. If your original battery matches the EH, square connector type, this pack has enough buyer-confirmed evidence to be a practical way to restore cordless talk time.
FAQs
Are these batteries compatible with my BT-18433 cordless phone?
They are listed as compatible with BT-18433 and related BT-184342 family models. To be safe, confirm your current battery’s part number family and that the connector type (EH plug, square connector form) matches what your handset uses.
What are the voltage and capacity of this battery pack?
The pack is rated at 2.4V and 550mAh, using NiMH AAA x2 cells.
Do I need to fully charge the battery after installing it?

Will these fit if my connector looks different?
Compatibility depends on matching the connector type. If your original battery uses a different plug shape or connector style than the EH plug and square connector this battery uses, you should avoid buying and choose a pack that matches your connector exactly.
