The NP-BG1 battery charger is designed to recharge NP-FG1/NP-BG1 lithium-ion batteries used in Sony Cyber-Shot cameras like DSC-W100, W30-W50, H50-H55, and H-series models. It uses a compact AC adapter with LED charging indicators, ensuring compatibility with Sony’s power specifications for safe, efficient charging cycles. Charging time typically takes 2-3 hours for a full 1240mAh capacity.

Which Sony Cameras Are Compatible with the NP-BG1 Charger?
Compatible models include Cyber-Shot DSC-W100, W30, W35, W40, W50, WX1, H50, H55, H3, H7, H9, H10, and H20. These cameras rely on NP-FG1/NP-BG1 batteries, which share identical voltage (3.6V) and dimensions. Always verify battery model codes (e.g., NP-FG1 InfoLithium) printed on your device to ensure charger compatibility.
| Camera Model | Release Year | Battery Type |
|---|---|---|
| DSC-W100 | 2006 | NP-BG1 |
| DSC-H50 | 2008 | NP-FG1 |
| DSC-WX1 | 2009 | NP-BG1 |
Owners of older Sony cameras should note that some regional variants may use different battery labels despite identical specifications. For example, the NP-FG1 is functionally equivalent to the NP-BG1 but marketed under separate product codes in North America and Europe. Hybrid models like the HX5V also support these batteries if they include the “Battery Compatible with NP-FG1” notation in their manuals. When purchasing replacement batteries, prioritize Sony-certified sellers to avoid counterfeit products that may damage your charger or camera.

| Symptom | Possible Cause | Solution |
|---|---|---|
| No LED indicator | Loose power connection | Check AC adapter seating |
| Intermittent charging | Dirty battery terminals | Clean with 90% isopropyl alcohol |
| Overheating during charge | Faulty thermal sensor | Replace charger unit |
If the charger emits a high-pitched buzzing noise, immediately unplug it and inspect for swollen capacitors or burnt odors. For cameras showing “Invalid Battery” errors after charging, perform a firmware update through Sony’s support portal. Users in humid climates should store chargers in airtight containers with silica gel packs to prevent moisture-related corrosion on internal circuits. Always use surge protectors when charging in areas with unstable power grids to safeguard against voltage spikes.
What Safety Features Does the NP-BG1 Charger Offer?
Sony’s OEM charger includes overcharge protection, short-circuit prevention, and temperature monitoring. The IC chip automatically stops charging at 100% capacity, while flame-retardant materials reduce fire risks. Third-party chargers often lack these certifications, potentially damaging batteries or cameras.
Can You Use Third-Party Chargers with NP-FG1 Batteries?
While generic chargers are cheaper, they may lack Sony’s proprietary voltage regulation, risking overcharging or reduced battery lifespan. Reputable third-party options like Wasabi or Kastar include safety certifications but still show 10-15% slower charging speeds compared to OEM chargers in lab tests.
What Are the Environmental Impacts of Battery Charging?
Lithium-ion batteries in NP-BG1 chargers contain cobalt and lithium, requiring proper recycling. Sony’s charger meets ENERGY STAR efficiency standards, consuming 0.5W in standby mode. Always unplug chargers after use to reduce phantom energy drain by 8-10% annually.
Are Newer Sony Models Compatible with NP-BG1 Chargers?
Recent Sony cameras like ZV-1 or RX100 VII use updated NP-BX1 batteries, which aren’t cross-compatible. However, older HX90V and some A6000-series cameras still support NP-FG1 packs. Check Sony’s compatibility database for hybrid models.
How Do You Optimize Battery Lifespan with This Charger?
Avoid partial charges; let batteries drain to 10% before recharging. Store at 40-60% charge in 15-25°C environments. Sony recommends full discharge cycles every 30 charges to recalibrate battery meters.
Expert Views
“Sony’s OEM chargers maintain precise voltage curves that third-party units struggle to replicate. In our stress tests, generic chargers degraded battery capacity 20% faster after 100 cycles. For photographers relying on Cyber-Shot cameras, investing in genuine accessories pays long-term dividends.” – John Keller, Power Systems Engineer at CameraBatt Labs
Conclusion
The NP-BG1 charger remains essential for Sony Cyber-Shot users prioritizing safety and longevity. While third-party alternatives exist, Sony’s engineering ensures optimal performance for DSC/H-series cameras. Always prioritize certified accessories and proper maintenance routines.
