Approx. 13 years<br />
At +25 °C<br />
Approx. 9 years<br />
At +30 °C<br />
Approx. 7 years<br />
At +35 °C<br />
Approx. 5 years<br />
At +40 °C<br />
Approx. 3 years<br />
At +45 °C<br />

1) For storage, installation and operation of the lead-acid batteries, the<br />
appropriate DIN/VDE regulations or the country-specific directives (e.g.<br />
VDE 0510 Part 2/EN 50272-2) must be observed. The battery location must<br />
be sufficiently ventilated, potential ignition sources must be at least 50 cm<br />
away.<br />
