About Batteries Warning • Batteries shall not be exposed to excessive heat such as sunshine, fire or the like. • Dry batteries shall not be subjected to charging. New batteries Purchase the newest (freshest) batteries possible. Temperature Battery life ratings are based on operation at 20˚C (68˚F). Especially at a lower temperature, battery life is shortened. Keep spare batteries and if possible, use NiCd batteries. Continuous use Batteries are drained more quickly by continuous use than by intermittent use. Storage Store batteries in a cool, dry place, below 20˚C (68˚F). Battery brand Do not mix battery brands or models, or new and old batteries. Disposal Do not dispose of batteries by burning, and never disassemble batteries. NiCd batteries Compared with regular batteries, NiCd batteries offer a faster recycling time and greater efficiency at low temperatures. Before charging NiCd batteries, thoroughly read the instructions for the batteries and battery charger. Batteries with a "+" terminal that exceeds 6mm (0.23") in diameter cannot be used. 142 DC Units SD-8/SD-7 Nikon DC Unit SD-8 or SD-7 can be used as an optional external power source to enhance flash capacity and provide faster recycling time. To use the DC Unit, connect its power cord SC-16 to the SB-26's external power terminal. Even when powered with the DC Unit, the SB-26 still requires batteries inside the flash unit. Do not remove the batteries. In continuous shooting with the DC Unit, to prevent flash head deterioration caused by heat, do not exceed the maximum number of flash listed below. It is recommended to rest for more than 10 minutes after firing near the maximum numbers. Maximum consecutive firing SB-26 Flash mode Maximum number of flash SD-8 SD-7 TTL Auto Flash H 15 15 Non-TTL Auto Flash A 15 15 Manual Flash D 15 (at full or 1/2 power) 40 (at 1/4 power or less) 15 (at full or 1/2 power) 40 (at 1/4 power or less) Repeating Flash G 15 15 Power Bracket SK-6 Enables you to use your SB-26 as a grip-type flash. In addition, by installing batteries in the SK-6, you can use it as an external power source for SB-26. If SB-26 is already powered by the SD-7 or SD-8, the SK-6 can be used as a secondary external power source. Specifications All performance data are for normal-temperature operation (20° C/68° F). Electronic construction: Automatic Insulated Gate Bipolar Transistor (IGBT) and series circuitry.
