Usually makes lithium-ion batteries the long-term economical choice. High-performance attributes further underscore the value of lithium-ion batteries, including zero negative memory effect, high power density to weight ratio, and a near-flat power curve at the end of charge.
The safety problems of lithium batteries in the past are no longer a problem for modern models, and they have passed extrusion and puncture tests many times without catching fire. Additionally, these lithium batteries do not contain heavy metals or hazardous substances, so there is minimal risk to human health and the environment if damaged.
In addition, the built-in BMS monitoring management chip can prevent the battery pack from overcharging, overdischarging, overheating or short circuit. This standard technical feature ensures that internal operational safety is separated from the risk of external damage.

FQA:
1.What is tubular gel battery?
The tubular gel batteries are batteries in which a gelling agent is added to the electrolyte to reduce the movement of electrolyte in the battery case. This avoids the threat of spills and increases the number of the cycle which the battery can perform.
2.How long does a tubular gel battery last?
Gel batteries with positive tubular plates achieve a proven service life in stationary applications of more than 15 years. At high temperatures, the behavior is excellent and the negative impact of high temperatures on high rate discharges is small as compared with AGM batteries.
3.Is tubular better than gel?
In high-demand applications, Tubular batteries also offer better performance than Gel batteries. This is due to their higher capacity, which allows them to deliver more power and maintain a stable voltage during periods of high demand.
4.Is gel battery better than regular?
While comparing these two battery types, we discovered that gel batteries are less prone to leak and they tend to last longer since they cannot be corroded by metal or water. On the other hand, acid batteries are known for their fast charging capabilities and easy recyclability.
