Tubular Battery

What are tubular batteries

Unlike regular lead-acid batteries, the tubular battery employs technology that seals the active material into polyester tubes called gauntlets, ensuring a longer life. The regular ones paste the active material onto a plate. All tubular batteries act similarly but of course, they are not all made the same the differences come in the composition of the alloy in the positive support structure. Another factor is how the main backbone of the plates, called the spine, is cast. Gravity Casting is the most simple form and while these work well it is nowhere near the other 2 grades. Low Pressure Casting and HADI Casting, with the latter being the best in the battery industry. These 2 technologies make for better batteries, the individual advantages just become exponentially better as these technologies are applied.

Advantages of tubular batteries

Due to the construction, these batteries are tougher and more durable, this helps them perform consistently at higher temperatures. This helps with high cyclic applications, which can generally cause a lot more fatigue in regular batteries. As a lot of batteries are used for high-end applications the tubular battery is a better choice due to the mentioned advantages. Tubular batteries also require a lot less maintenance and can charge much faster than regular batteries. Another advantage is the long standby life in comparison to other batteries. 

Tubular batteries are available at a higher price point due to their more complicated construction requirements. But are worth the money in the long run as they outperform plate batteries. In Pakistan, some of the brands producing tubular batteries include Phoenix and Osaka.
