Up to 17% off
New arrival
From $81.99 USD $97.99
Shipping calculated at checkout.
Fits Realistic 23-187 digital cameras and camcorders requiring 12V Ni-MH battery packs.
12V nominal voltage and 1800mAh capacity restore full power for video recording and photo capture.
Connector orientation matches OEM Realistic pack; physical dimensions 143 x 62 x 21mm ensure proper slot alignment.
We bench-tested this Ni-MH cell on a standard camera charger; BMS accepted the pack with no fault codes on first insertion.
On first use, fully charge this cell in your camera body or OEM charger before extended shooting — Realistic camera bodies map battery-remaining display to the discharge curve during that initial cycle.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

REALISTIC 23-187 — 12V Ni-MH Replacement Battery (23-187)

This is a 12V, 1800mAh Ni-MH replacement battery for REALISTIC camcorders and digital cameras that run on the 23-187 cell. It also cross-references against SAMSUNG, SANYO LA2312, and SEARS 5399 part numbers, covering a shared platform across those brands. If your original battery no longer holds a charge or fails to register on the camera body, this cell restores power to the device.

  • Cross-platform compatibility: The 23-187, SANYO LA2312, SAMSUNG, and SEARS 5399 designations cover cameras that share the same 12V Ni-MH voltage rail and connector footprint. The BMS on these bodies reads cell voltage at startup — a matched voltage profile means the camera accepts the cell without an incompatibility flag.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge sequences and monitored BMS handshake behaviour at the camera body. The cell held stable voltage across the discharge curve with no mid-cycle cutoff events.
  • First-cycle conditioning for Ni-MH camera cells: Ni-MH cells benefit from one full charge cycle inside the OEM charger or camera body before heavy shooting. This lets the camera's battery-remaining display map correctly to the new cell's discharge curve — skipping this step causes the indicator to read inaccurately for the first several uses.

Why the 23-187 battery indicator reads incorrectly after a fresh install

Camera bodies running Ni-MH cells use voltage-threshold maps to estimate remaining charge. A new cell has a slightly different discharge curve than a worn original — the camera reads the voltage steps and maps them to the wrong percentage points. This causes the indicator to jump or drop suddenly during use. Running one complete charge-discharge cycle from within the OEM charger recalibrates the camera's reference baseline for the new cell.

Camera body displaying no battery or refusing to power on after installing replacement

Some REALISTIC and cross-compatible camera bodies require the cell to present a minimum voltage at startup before the BMS clears the battery-present check. A new Ni-MH cell shipped in partial charge state can sit just below that threshold. Place the battery in the OEM charger first and charge to full before inserting it into the camera body — this brings cell voltage up to at least 12V nominal, which satisfies the BMS startup check.

Frequently Asked Questions

My camera shows a dead battery icon right after I put the new 23-187 cell in — is the replacement faulty?

It is not faulty. Ni-MH cells ship in a partially discharged state, and some REALISTIC camera bodies require a minimum voltage at the terminals before the battery indicator clears. Charge the cell fully in the OEM charger before inserting it into the camera body. Once cell voltage reaches 12V nominal, the body accepts it and the icon clears.

The battery percentage is jumping around — it shows 80%, then drops to 20% within a few shots. What's happening?

The camera's remaining-charge indicator is calibrated against the discharge curve of the original cell. A new Ni-MH replacement has a slightly different voltage-drop profile, so the body maps voltage readings to the wrong percentage points. Run one complete charge and discharge cycle through the OEM charger or camera body. After that cycle, the indicator tracks the new cell's curve accurately.

Flash recycling feels slower than it used to — the ready light takes longer between shots. Is this a battery issue?

Yes. Flash capacitor recharge draws a heavy current pulse from the cell each cycle. As a Ni-MH cell moves toward the end of its charge, internal resistance rises and the capacitor takes longer to reach full charge voltage. If you are mid-charge and seeing this, the cell is likely below 10.8V — recharge fully and test again. If it recurs at the start of a fresh charge, check that the cell seated contacts are clean and making full contact in the battery compartment.
