Notes on batteries • Lithium batteries have approx. 1.1 to 1.2 times the power capacity of alkaline-manganese batteries. • Lithium batteries feature greater efficiency at low temperatures when compared with alkaline-manganese batteries. Lithium batteries boast consistent performance in terms of recycling times and number of flashes, regardless temperature changes. • NiCd batteries boast a constant recycling time regardless of temperature changes when compared with other types of batteries. Recommended for use in temperatures as low as 0°C (32°F). • Ni-MH batteries feature a constant recycling time but a little longer recycling time at low temperatures when compared with NiCd batteries. However, Ni-MH batteries maintain their efficiency regarding the number of flashes regardless of temperature changes. Notes on using alkaline-manganese and lithium batteries • Non-rechargeable batteries such as alkaline-manganese and lithium batteries should not be charged in a battery charger as they may explode. • Lithium batteries incorporate internal safety switches. When the battery becomes hot, its safety circuit is activated, cutting off power. This often occurs when the SB-28 is operated in the repeating flash mode. The flash ready-light will not light up after firing approx. 24 exposures. However, battery power will recover when the temperature goes back to normal. Notes on using rechargeable NiCd and Ni-MH batteries • When recharging batteries, be sure to use the battery charger specified by the battery maker and read the instructions thoroughly. Recharging should be done in temperatures from 10° to 30°C (50° to 86°F). • Do not recharge NiCd or Ni-MH batteries with their terminals reversed in the charger or before the batteries have cooled off sufficiently. • Overcharging and excessive use may shorten battery life. Do not overcharge and be sure to turn the SB-28 off when not in use. • Because flash consumes a large amount of battery power, rechargeable batteries may not operate properly before reaching the end of their stated life-span or the number of charging/discharging as specified by the battery manufacturer. • If NiCd or Ni-MH batteries do not last as long as they should after being fully charged, they are approaching the end of their life. Replace them with a new set. 88
