NEEWER NW665 2040mAh battery pack for flash
Product description
This compact replacement battery keeps your NEEWER NW665-C speedlite running through long shoots and event work, offering higher capacity for extended flash bursts and quicker turnaround between exposures. It delivers extended runtime for photographers who need reliable power during wedding shoots, studio sessions and location work.
Key Points
The battery is specifically for the NW665-C E-TTL II Speedlite and replaces the original pack to restore full functionality. It uses lithium ion polymer cells with higher energy density, which helps reduce weight while maintaining prolonged performance. According to the manufacturer, a single full charge can provide up to 650 full-power flashes, which helps when you cannot pause to recharge mid-session. The pack includes multiple internal protection features for overcharge, over-discharge, over-voltage, over-current and overheating, improving safety during regular use. Lightweight at about 131.4 g, it is simple to carry in a camera bag for on-location assignments 😊.
Benefits
This replacement battery gives a noticeable increase in available flash cycles compared with older packs, allowing more continuous shooting between charges. Faster recycling and steadier output reduce the chance of missed shots when working with fast-paced sequences. It is also useful as a spare to keep in rotation while another pack charges. Consider that the quoted flash count is according to the manufacturer, and actual performance will depend on shooting settings and ambient temperature. The pack may not work with other NEEWER models, so double-check compatibility with your speedlite before fitting. ⚡️
