27910 Cordless Telephone Battery Compatible with AT&T 89-1323-00-0 Motorola SD-7501 (Pack 2)

Quick take

This 27910 cordless telephone replacement battery is a NiMH 3.6V 600mAh pack designed to match specific original battery part numbers, including replacements used in Motorola SD-7501 series and certain AT&T and RadioShack cordless models. It is best for people who need a straightforward battery swap to restore charging and everyday talk time, with the main caveat being compatibility depends on matching your phone’s battery part number and model requirements.

Pros and cons

Pros

  • 3.6V NiMH 600mAh replacement battery with rechargeable design
  • Sold as a 2-pack, useful if you have multiple handsets
  • Compatibility is tied to specific replaceable battery part numbers (27910, 89-1323-00-00, SD-7501, 23-959)
  • Review evidence commonly mentions correct fit and reliable everyday operation

Cons

  • Not a universal battery, so you must verify your handset uses the 27910-style battery
  • Review evidence is limited to “fits and works” style comments, with less detail on long-term runtime differences

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence for this battery is relatively consistent around basic replacement outcomes. Multiple comments focus on whether the batteries fit correctly and whether the cordless phones resume normal charging and operation. Overall sentiment leans positive for day-to-day usability, with less detailed discussion about specific runtime improvements or battery longevity beyond “works for a long time” type statements. Because the review themes are mostly about fit and basic functionality, buyer-review evidence is too limited to reliably estimate changes in talk time versus the original battery.

What this battery is, and who it’s for

The 27910 battery is a rechargeable NiMH cordless phone battery designed to restore function when older handsets stop holding charge. It is intended for phones that use the matching battery specs and part-number replacements, including 27910 and 89-1323-00-00 (also listed alongside SD-7501 and 23-959).

This is a practical choice if you want a drop-in replacement for a compatible Motorola, AT&T, or RadioShack cordless handset, and especially if you need more than one battery (since the pack includes two).

Compatibility: the detail that matters most

For cordless batteries, matching is everything. This pack targets:

  • Battery specs: 3.6V, 600mAh, NiMH, rechargeable
  • Replacement part numbers: 27910, 89-1323-00-00, SD-7501, 23-959
  • Model compatibility lists: includes multiple Motorola phone models such as C50, C51, E32, E33, E34, E51, E52, several MD- and SD-series models, and multiple SD-750x variants; also lists a range of AT&T handset models and RadioShack 23-959-related models

If you’re unsure, the safest approach is to confirm the battery part number currently in your handset, then cross-check that it matches the replacements listed above.

Pros and cons, in real buying terms

Pros

  • More than one handset covered: the 2-pack helps if you have multiple cordless stations or want a backup.
  • Designed for specific phones: compatibility is organized around known replacement part numbers and listed handset models.
  • Buyer feedback centers on fit and basic function: reviewers frequently describe the batteries as working like expected replacements.

Cons

  • Compatibility risk: if your handset uses a different battery part number or a different voltage, this won’t be the right fix.
  • Limited runtime detail: reviews don’t provide enough technical detail to compare talk time versus other replacements.

Should you buy it? (Quick verdict)

Choose this 27910 cordless telephone battery pack if your Motorola, AT&T, or RadioShack handset uses the 27910-style replacement battery and you want a reliable, spec-matched NiMH 3.6V 600mAh replacement. If you’re missing the original battery part number or your handset is from a different family, skip this and verify compatibility first.

Alternatives to consider (without overcomplicating it)

If you’re deciding between replacement options, focus on compatibility and specs first. Look for:

  • Same voltage and capacity: ensure the replacement is 3.6V NiMH and matches the intended capacity class for your handset.
  • Correct replacement part number: battery part numbers (like 27910 and 89-1323-00-00) are usually the fastest path to an accurate match.
  • Right pack size: if you have two handsets, a 2-pack often reduces the hassle of doing the upgrade twice.

When those match, “brand” is secondary. When they don’t, any battery can underperform or fail to fit.
