F E ATURES AND BENEFITS
1973. The purity of the materials used is key to supporting this lead-

replacements and the cost associated with it, combined with higher
reliability and fewer system failures, result in a lower long-term cost

(offering up to 200 full cycles), pure lead-tin batteries provide 50% to
200% greater full cycle capability. C Y C L O N product will deliver more
than 300 cycles (100% DOD, C/5). And, because C Y C L O N i n c o r p o r a t e s

C Y C L O N, h o w e v e r, offers a ten-year design life at 25° C, C/5, to 80%
of rated capacity. At 20° C, C Y C L O N single cells offer a fifteen-year
design life.
d e l i v e ry of a pure lead-tin battery results from its low internal resistance.

means our batteries are able to discharge and recharge their power
more quickly and efficiently and offer greater application flexibility.
The pure lead-tin construction also gives more watts-per-unit weight
at high discharge rates.
strong construction and high vent pressures, these cells will maintain
their performance and physical parameters in extreme conditions.
At high temperatures, the chemical reaction in a battery that causes
aging is accelerated. Pure lead-tin technology resists that chemical
reaction more effectively than alloyed lead, thus allowing a battery to
have a longer service life. At high temperatures, when conventional
lead batteries experience internal moisture loss from venting and case
side wall distention, the C Y C L O N Single Cell, with its steel can (jack-
et) and 50psi vent, does not experience these life-robbing conditions.

The company’s focus on battery-case integrity and high vent pressure,
coupled with pure lead-tin’s low grid-corrosion rate, means C Y C L O N
