Best of both worlds!. The original optics straight from the 50-70s paired with up to date modern technology. The lead gel type batteries are acid-free. Therefore rust caused by battery acid is a thing of the past. Opposed to the conventional type of battery the gel ones do not discharge as much. Thanks to the antimony-free lead composition the self-discharge is less than 3 % per month.
