How long does a 2V battery last?
The lifespan for 2-volt traction Gel cells is at least 15 years and the maximum number of full cycles is 1000-1500 when discharging to 20 % of capacity. These batteries are therefore highly suitable for larger systems that require intensive use and a very long lifespan.
