Rechargeable battery chargers and batteries for professional equipment
14 years old. Gear and prices may have changed since.
What the thread found
- Rechargeable consumer batteries are expensive and prone to being lost as small items, which is why many professionals prefer disposable batteries for portable devices
- Standard 9V batteries typically last around two days of continuous use in equipment like wireless microphones
- Rechargeable 9V batteries are generally considered poor performers and are rarely used compared to AA and AAA types
- Quick chargers generate excessive heat and use crude full-charge detection, potentially damaging rechargeable batteries, while trickle chargers are gentler
- Eneloop brand batteries hold a charge well over time and are available through consumer retailers
Depends on
- Discussion focused on consumer-grade equipment rather than professional broadcasting equipment
- No definitive recommendation was reached on which charger model is best
- One participant mentioned 9V drain issues but another reported normal two-day performance, suggesting the problem may be equipment-specific
- The viability of rechargeable systems for professional use was not conclusively determined
