One of the best golf series battery was born ---- EV series Tubular flooded lead-acid battery has 15
years of design life and new tube type battery technology ---TOPSURE® technology.
Positive plates of lead-acid batteries are mostly pasted plate, resulting in shedding of the active
material with the number of cycles to increase. so that the cycle life is shortened，But will not
appear in tubular lead-acid battery.
After our Thirty years of research, tubular cells and tubular plate technology has been considerable development, Application of new technologies EV series battery---TOPSURE® technology , effectively prevent shedding of active materials, increased use of life, not only to improve the utilization of the active material and high capacity, But also Improve deep-cycle capability. which is Suitable for High end applications. Complex design. Highly reliable compared to normal flat plate batteries.
Common pasted positive plate flooded battery life will not exceed ten years, deep cycling capability is relatively poor. EverExceed EV series batteries are 15 years stationary batteries and were developed for GOLF, and maintain more than 80% of capacity, it is the best choice for golf battery.
|Comparison between flat and tubular positive plates in flooded lead-acid batteries|
|Flat plate||Tubular||Explan ation of tubular advantages|
| Charge cycles
(at 80% DOD)
|50-800||1800||Lead selenium / low antimony alloy advantage|
|Medium||Low||The external shape of the positive plate allows for
easier movement for the electrolyte
|Thermal management||Medium||High||Because of the higher relative electrolyte amounts
and easier convective heat transport
|Electrical resistance||Mid-to-low||Low||Well defined pore sizes permit easy movement to
|Life expectancy||8 years||15+ years|
|Charge retention||Long||Longest||Because there is no electrolyte pollution from
