Five silver rectangular lithium-polymer batteries in a pack

Centenex Electronics

Centenex Electronics 5-Pack 1400 mAh 3.7 V Li-Polymer Battery for Palm Tungsten E T5 TX

SKU CH-42DR-C9ER3

Five-pack of 1400 mAh 3.7 V Li-Polymer replacements for Palm Tungsten E, T5 and TX handhelds

  • Five batteries keep multiple PDAs powered
  • 1400 mAh capacity extends runtime between charges
  • 7 V lithium-polymer chemistry matches original spec
  • Fits Tungsten E, T5 and TX models
  • Slim 3.55 mm profile slides into existing battery bay

Five-pack replacement cells

This bundle provides five lithium-polymer batteries built for the Palm Tungsten E, T5 and TX handhelds. Each cell delivers 1.4 Ah at 3.7 V for 5.18 Whr of capacity. The pack suits owners who need several ready spares for daily syncing or field work. Buyers whose device is not one of the three listed models cannot use these cells.

Thermal and power profile

Lithium-polymer chemistry keeps self-discharge low during weeks of storage. Normal PDA loads draw only modest current, so the packs run cool and silent in a shirt pocket. No active cooling or special charging circuitry is required beyond the handheld’s own controller. Users expecting high-drain applications such as continuous GPS logging will see shorter run times per charge.

Included accessories and fit

The five cells ship loose without a charger, cables or installation tools. Each battery measures 60.95 x 34.29 x 3.55 mm and matches the original UP383562A footprint for a direct swap. Japanese cells are cited for consistent cycle life. Shops looking for a bundled cradle or multi-bay charger will not find one in this package.

Questions about this item

How do I install these 60.95 x 34.29 x 3.55 mm Li-Polymer packs in my Tungsten, and what step do people get wrong?

Power off the PDA, remove the back cover, disconnect the old pack's connector, then snap in the new 1400 mAh 3.7 V unit; the common error is forcing the plug in reversed — align the keyed header before pressing.

What maintenance or replacement will the 5-pack of 1.4 Ah cells need later?

Store unused packs at roughly half charge in a cool place; cycle each spare every few months to prevent deep discharge, and replace any cell that swells or no longer holds a full day's run-time.

What limit appears first during sustained use of the 5.18 Whr battery?

The 1400 mAh capacity sets the runtime ceiling; under continuous load the PDA will shut down once the 3.7 V output drops below its minimum operating threshold.
