BRAUN DS Charger for Olympus/Fuji vs Sony: What Fits?

Match your camera battery to the right BRAUN DS charger: the Olympus/Fuji version or the Sony version. Follow these steps to check voltage, polarity, and fit before charging.
Quick answer
Use the BRAUN DS-Ladegerät OLYMPUS/FUJI for Olympus and Fujifilm batteries, and the BRAUN DS-Ladegerät SONY for Sony batteries. Both accept 3.6V to 7.4V lithium-ion packs and share the same charging logic, so the deciding factor is the battery model and its physical contacts, not the charger’s feature set.
Why the two versions exist and when one will not work
The Olympus/Fuji and Sony versions look nearly identical and share the same input range (110–240V or 12V) and output (450mA at 4.25V or 8.55V). The difference is in the battery cradle and contact arrangement, which is tailored to the battery families named on each charger. A Sony battery may physically fit the Olympus/Fuji cradle but fail to make reliable contact, and vice versa.
If your battery is not an Olympus, Fujifilm, or Sony model, neither charger is the right choice. The DS series is built around those families, and the catalog does not list adapters for other brands. In that case, look for a charger that explicitly names your battery model rather than forcing a fit.
What the shared electronics mean for your charging routine
Both DS chargers use microprocessor control and a temperature sensor that cuts charging if the battery exceeds 40°C. They also use minus-delta-V termination, which stops the charge when the battery reaches full. These features make the chargers suitable for routine top-ups, but they do not replace checking that the battery’s voltage and chemistry fall within the supported 3.6V–7.4V lithium-ion/lithium-polymer range.
Because the output current is limited to 450mA, large-capacity packs will take longer to charge than with a high-current charger. That is a trade-off for gentler charging, not a defect. Plan overnight charges for big batteries rather than expecting a fast turnaround.
How to pick and use the right DS charger
- Read the battery label: Check the voltage (3.6V, 3.7V, 7.2V, or 7.4V) and chemistry (lithium-ion or lithium-polymer). If the voltage is outside 3.6V–7.4V or the chemistry is not lithium-based, stop—neither DS charger is suitable. A 3.6V–7.4V lithium pack is the only safe starting point.
- Match the brand family: If your battery is an Olympus or Fujifilm model, choose the BRAUN DS-Ladegerät OLYMPUS/FUJI. If it is a Sony model, choose the BRAUN DS-Ladegerät SONY. Do not assume a physical fit means electrical compatibility. Brand family decides the charger version; voltage alone does not.
- Check the contacts and cradle: Slide the battery into the charger before plugging it in. It should sit flat and engage the contacts without force. If it rocks or needs pressure, you have the wrong version—do not bend contacts to make it fit. A battery that needs force is the wrong battery for that charger.
- Connect to power and confirm charging: Plug the charger into a 110–240V outlet or a 12V source. The charger’s electronics will regulate the current; there is no manual voltage switch. If the battery becomes noticeably hot early in the charge, disconnect it and recheck the battery’s condition. The charger manages voltage automatically; heat is your warning sign.
- Remove the battery when full: The charger stops charging at full via minus-delta-V detection, but leaving the battery in the charger for days adds no benefit. Take it out once charging completes and store it at room temperature. Full termination is automatic, but prompt removal is still good practice.
Product facts
- BRAUN DS-Ladegerät OLYMPUS/FUJI: Charges lithium-ion and lithium-polymer batteries from 3.6V to 7.4V with microprocessor control. This covers common Olympus and Fujifilm camera packs, but you still need to confirm your battery’s voltage is within that range.
BRAUN DS-Ladegerät OLYMPUS/FUJI - BRAUN DS-Ladegerät SONY: Includes a temperature sensor that interrupts charging if the battery exceeds +40°C. This adds a safety check during charging, but it does not replace using the correct cradle for your Sony battery.
