BT183342/BT283342 2.4V 800mAh Ni-MH Battery Pack (Pack of 2)
Quick take
The BT183342/BT283342 2.4V 800mAh Ni-MH battery pack (sold as a 2-pack) is a replacement-style battery for select VTech and AT&T cordless phone handsets. It’s rechargeable and includes protection features (over-voltage, over-current, over-charge, and short-circuit) to help keep charging safer. The key caveat is compatibility, so confirm your handset’s original battery model number before ordering.
Pros and cons
Pros
- Rechargeable Ni-MH cells (2.4V, 800mAh) intended as a like-for-like replacement.
- Pack includes 2 battery packs, useful if you have multiple handsets.
- Protection features include over-voltage, over-current, over-charge, and short-circuit protection.
- Multiple compatibility paths listed for VTech and AT&T cordless models.
Cons
- Fit is model-specific, so the wrong handset battery model can lead to poor physical fit.
- Battery performance (runtime) depends on your handset and charging behavior, so expectations should be set around “replacement” rather than a major upgrade.
What buyers think
Buyer-review evidence is generally positive, with repeated themes around easy installation, getting charging working again, and restoring everyday phone use. Several buyers describe the replacement packs as fitting properly and working well in compatible AT&T or cordless units, with notes like “phones are charging well now” and “life of the battery is good.” A small amount of feedback also suggests fit issues can happen if the battery does not match the handset closely, reinforcing the importance of checking the exact battery model and intended replacement pack.
What this battery pack is for
This is a rechargeable Ni-MH battery pack rated at 2.4V and 800mAh, built as a replacement for cordless phone handsets that use the BT183342/BT283342-style battery configuration. It comes as a 2-pack, which is convenient if your system has more than one handset or if you want a spare replacement battery on hand.
Key specifications that affect compatibility
- Battery type: Ni-MH (rechargeable)
- Voltage: 2.4V
- Capacity: 800mAh
- Cell layout: AAA*2 cells
- Pack count: 2 batteries included
Beyond these headline numbers, the practical fit matters. Reviews include at least one report of the pack not fitting well in a phone, which is typically what you’d expect when the handset expects a slightly different battery housing or connector arrangement. That’s why matching the original battery model is the most important step.
Compatibility notes for VTech and AT&T cordless phones
The battery is marketed for a list of compatible VTech and AT&T models, including common groups such as (examples) CS6709, CS6609, CS6509, CS6409, EL52100, CS6114 and many others. Because cordless handset lineups can have multiple battery revisions, treat the model list as a starting point and verify your current handset’s battery model number (often printed on the original pack) before purchasing.
Protection features and what they mean
This pack includes over-voltage, over-current, over-charge, and short-circuit protection. For buyers, that typically translates to safer charging behavior in normal use, particularly if the charging contact or charging circuitry is under stress during routine everyday charging cycles. It does not replace good charging habits (for example, using the correct charger and ensuring proper contact), but it adds an extra layer of protection design.
Pros and cons recap
Best for
- People with compatible VTech or AT&T cordless phone handsets that use the BT183342/BT283342 battery family.
- Households with multiple handsets who want two replacement packs instead of buying one at a time.
- Buyers looking for a cost-sensitive way to restore basic charging and handset operation.
Who should avoid it
- Shoppers who cannot confirm their handset’s exact battery model number and expected pack fit.
- Anyone expecting a major runtime upgrade compared to a worn original battery, rather than a standard replacement.
How to check you’re buying the right replacement
- Find the battery model number on your current pack (often labeled with something like BTxxxxxx).
- Confirm voltage and capacity match what your handset expects (this pack is 2.4V, 800mAh Ni-MH).
- Compare physical fit (connector style and battery housing). Even when voltage matches, a slightly different pack design can cause poor fit.
- Match to your handset’s model list for VTech and AT&T units.
Price and availability
The listing price is positioned as a low-cost alternative to replacing an entire handset or cordless system. If you have more than one handset, choosing a 2-pack can improve value, but only if both handsets truly use the same compatible battery type.
Alternatives to consider
- Original-brand replacement batteries: often easier to match physically, especially when you can buy the exact OEM battery model, but they can cost more.
- Other compatible replacement packs: choose based on the same battery type (Ni-MH), voltage (2.4V), and capacity (800mAh), plus the exact handset compatibility and fit requirements.
Verdict
The BT183342/BT283342 2.4V 800mAh Ni-MH battery pack (2-pack) is a practical replacement option for compatible VTech and AT&T cordless phones, with protection features built into the battery pack design. The biggest determinant of success is whether it matches your handset’s expected battery model and physical fit, and the buyer-review pattern supports that compatible installs tend to work smoothly and restore charging.

It comes as a pack of 2 battery packs, which is useful if you have more than one handset or want a spare.
Does this replacement improve call quality or signal?
