The fully charged battery provides five starter switches 40 seconds each with 30 seconds breaks under temperature 20-35°C, and 3 switches at 5°C.
Service life durability is 180 fours in the air for 15 months, 6 months with capacity 45AH, and the last month with capacity not less than 40AH under discharge with a current of 9A. During this period the battery provides 180 independent switches under capacity lost not more than 5AH at each switch. The amount of flights without independent starter switches in 180 flying hours is not limited.
The battery is manufactured and delivered dry (without electrolyte). The quality of batteries meets requirements of TU U3.07-057.58948.001-96.
