Compact NiCd Cells for Legacy Devices

These Sanyo 1/3 AAA flat-top batteries deliver 1.2 V and 50 mAh in a 50-piece pack. They suit older cordless phones, medical instruments and compact electronics that require this exact form factor. The nickel-cadmium chemistry tolerates high discharge rates and recharges up to 500 cycles.

1/3 AAA Size and Flat-Terminal Interface

Each cell measures 15.8 mm long and 10.5 mm in diameter with flat terminals on both ends. This geometry matches equipment designed for the 1/3 AAA standard; devices with spring contacts or button-top slots will not make reliable contact.

Steady Output Through Extended Use

NiCd chemistry maintains voltage under continuous load better than many alternatives, so the cells sustain performance during long talk-time or monitoring sessions. The 500-cycle rating means the pack supports years of daily charge-and-discharge routines without sudden capacity collapse.

Questions about this item

What run-time does the 50 mAh capacity deliver in a typical device?

At 50 mAh a 1.2 Volt NiCd cell will power a 10 mA load for roughly five hours before needing a recharge.

Does the flat-top terminal work with standard AAA spring contacts?

The flat-on-both-ends terminal has no protruding button, so it only fits holders designed for flat-top cells or solder-tab connections.

Will the 10.5 mm diameter and 15.8 mm length fit a 1/3 AAA battery compartment?

Yes, those are the standard 1/3 AAA dimensions, so the cells seat correctly in any properly sized holder.
