- 7.4V 1140mAh lithium-ion cell delivers consistent power across multi-hour shoots without the voltage sag of cheaper alternatives
- Drop-in equivalent for Olympus BLN-1 fitting OM-D E-M1, E-M5, E-M5 Mark II, Pen E-P5 and Pen-F bodies
- 51g weight matches OEM spec so camera balance and handling stay identical to your original battery
- No memory effect means you can top up between shoots without degrading long-term capacity
- Fast-charge compatible so the battery is ready when you need it, not hours later
- 2-year warranty backs the cell against premature failure, unusual for third-party power
- Lithium-ion chemistry holds charge during storage better than NiMH, so the spare in your bag is still live weeks later
- Manufactured to OEM dimensional tolerances for secure fit in the camera compartment with no play or contact issues
- Not compatible with Olympus-branded grip accessories, camera bodies only
Built to Duracell's exacting manufacturing standards, this lithium-ion rechargeable delivers dependable power across a range of compatible camera bodies. The multi-fit design means one battery works with several makes and models, reducing the number of spares you need to carry and simplifying your kit when you shoot across multiple systems.
Lithium-Ion Performance
Lithium-ion chemistry offers a high energy density in a compact form factor, so you get substantial runtime without adding bulk to your camera bag. Expect hundreds of shots or extended video recording on a single charge, depending on your shooting style and camera settings. Worth noting: lithium-ion cells reach peak performance after three full charge-discharge cycles, so initial capacity may feel conservative until the battery is properly conditioned.
Manufacturer-Equivalent Output
This replacement is engineered to match or exceed the output characteristics of the original equipment battery. Voltage, capacity and discharge curves are calibrated to deliver the same operational envelope, so autofocus speed, burst rates and video recording times remain consistent with what the camera body expects. No performance compromise when you swap in a spare.
Two-Year Limited Warranty
Every cell is backed by a two-year limited warranty, covering manufacturing defects and premature capacity loss under normal use. That level of coverage reflects the brand's confidence in build quality and provides tangible reassurance when you're investing in backup power for professional or high-stakes personal shoots.
Why a Spare Matters
A single battery rarely covers a full day's shooting, especially if you're recording video, using live view extensively, or working in cold conditions that accelerate drain. Carrying a charged spare means you can swap cells in seconds and keep shooting through the decisive moment, rather than hunting for a wall socket or watching the low-battery icon blink during a paid job. This Duracell equivalent gives you that insurance at a lower cost than OEM spares, without sacrificing reliability.
Duracell has built its reputation on delivering power when it counts. This BLN-1 equivalent upholds that standard, offering the same peace of mind you expect from the brand, just applied to your camera system instead of your TV remote. Stock DROBLN1 as your go-to spare and eliminate battery anxiety from your pre-shoot checklist.
