Spare alkaline 12V(L)A23 battery

Battery-operated SVS products are supplied with high-quality alkaline 12V(L)A23 batteries as standard.
The capacity is designed in such a way that a battery in a hand-held transmitter that is actuated 10 times a day for one second has a theoretical life of approx. 2 to 3 years. Use in low temperatures and continuous use can reduce the capacity significantly, however. Unless the hand-held transmitter is used significantly more frequently, we therefore recommend changing the batteries regularly every 1 to 1.5 years.
For all 1 - 4 channel hand-held transmitters in the SH-12 and SH-7 series, except for the SHT-127 D, SHT-77 D, SHT-77 AB and SHT-12 BS.
