Quick Answer

If your Albrecht DR 855 or DR 860 radio won't hold a charge or powers off unexpectedly, the battery likely needs replacing. The correct replacement is the 27856 battery (6800mAh), which offers a significant capacity upgrade over the original. Before buying, confirm your radio model and check for simple fixes like cleaning the contacts.

Why Your Albrecht DR 855/860 Battery Fails

Like all rechargeable batteries, the one in your Albrecht DR 855 or DR 860 degrades over time. After a few hundred charge cycles, the internal cells lose capacity. You might notice the radio lasting only a fraction of its original run time, or it may shut down abruptly even after a full charge. In some cases, the battery swells slightly, making it hard to remove from the compartment.

Environmental factors also play a role. Extreme heat, frequent overcharging, or leaving the radio unused for months can accelerate battery wear. If you store your radio in a hot vehicle or charge it every day without letting it discharge, expect a shorter lifespan.

How to Diagnose a Failing Battery

Before ordering a replacement, rule out other causes. First, inspect the battery contacts on both the battery and the radio. Corrosion or dirt can prevent proper charging. Clean them gently with a dry cloth or a cotton swab dipped in isopropyl alcohol.

Next, test the charger. Plug it into a different outlet or try charging a known-good battery if available. A faulty charger can mimic a dead battery. Finally, if the radio works fine when plugged into the charger but dies immediately when unplugged, the battery is almost certainly the culprit.

Choosing the Right Replacement Battery

The correct part number for the Albrecht DR 855 and DR 860 is 27856. A replacement like the 27856 Battery for Albrecht DR 855 / DR 860 6800mAh offers a higher capacity than the original, giving you longer talk time between charges. It includes a 3-year guarantee, which provides peace of mind.

Be cautious with generic batteries that don't list the 27856 compatibility. Using an incorrect voltage or connector type can damage your radio. Stick to a battery specifically listed for the DR 855 or DR 860.

Extending the Life of Your New Battery

Once you install a fresh 27856 battery, follow a few simple habits to maximize its lifespan. Avoid fully draining the battery before recharging; lithium-ion cells last longer with partial discharge cycles. Remove the battery if you plan to store the radio for more than a month, and keep it in a cool, dry place.

Also, use the original charger or one with the correct voltage rating. Overcharging with a mismatched charger can reduce capacity over time. If your radio has a battery-saving mode, enable it to reduce power draw during standby.

Diagnosis: Is It Time for a New Battery?

  • Symptom: Radio runs for less than half the usual time, or powers off unexpectedly with a full charge indicator. This is the most common sign of a worn-out battery.
  • Likely Cause: The internal cells have degraded after repeated charge cycles. A swollen battery is a clear indicator of end-of-life. If the battery is swollen, stop using it immediately and replace it.
  • Corrective Action: Replace the battery with a compatible 27856 model. Ensure the radio contacts are clean and the charger works. A fresh 6800mAh battery should restore full performance.
  • Stop or Choose Another Option: If the radio still fails after a new battery, the issue may be internal (e.g., charging circuit). In that case, consult a professional repair service. Do not attempt to open the radio yourself unless you have electronics experience.
