Product Description The GP 23A is a high-performance, high-voltage battery designed to provide the necessary "surge" power for small electronic devices. Though similar in appearance to a standard AA battery, it is significantly shorter (about half the height) and packs a powerful 12V output. This battery is the global standard for RF (Radio Frequency) devices, specifically car alarm remotes, home security sensors, garage door openers, and wireless doorbells. GP's advanced alkaline technology ensures that even after months of inactivity, the battery can deliver the high-tension pulse required to transmit a wireless signal over long distances.

Key Features

  • High Voltage in Small Factor: Delivers 12V from a compact 28mm cell, essential for triggering wireless RF transmitters.

  • Leak-Proof Construction: Built by GP Batteries with high-quality seals to prevent damage to expensive remote control PCBs.

  • Superior Pulse Performance: Maintains stable voltage levels during the high-drain bursts required for signal transmission.

  • Mercury-Free Formula: Environmentally responsible 0% Mercury added design.

  • Universal Compatibility: Replaces all standard 12V 23A, MN21, and L1028 batteries.

  • Storage Temperature: 10°C to 25°C

Prototyping and Engineering Tips from Robogears

  • RF Transmitter Power: Most 433MHz and 315MHz wireless modules achieve their maximum range when powered by 12V. Using a 23A battery allows you to create a handheld remote that fits in a pocket but can trigger a receiver from over 50–100 meters away.

  • The "8-Cell" Secret: A 23A battery actually contains a stack of 8 tiny 1.5V button cells inside its metal jacket. This is how it achieves 12V. Because of this high internal resistance, it is designed for intermittent pulses, not continuous loads like driving motors or bright LEDs.

  • Low Capacity Awareness: With only ~55mAh of capacity, this battery will drain very quickly if used for a continuous light or a microcontroller like an Arduino. It is strictly a "signal battery."

  • Troubleshooting Tip: If your remote control only works when you are very close to the receiver, the 23A battery is likely dipping below 9V. Replace it with a fresh GP cell to restore the original transmission range.
