Finding a reliable battery for boats is certainly a challenge to owners. Several types of batteries came out, such as Nickel Metal Hydride (NiHM), Li-ion, Nickel Cadmium (NiCad), and so on, but research still continues.
The successor of Gates Energy (the original developer of AGM battery), EnerSys, has released a new innovation – the making of TPPL or Thin Plate Pure Lead battery – that could provide solution to the existing problem boat owners face each day.
A reputable writer who is passionate in discussing boat materials and equipment, Nigel Calder, has discoursed the advantages and limitations of the aforementioned battery.
TPPL is said to be the answer to boat owners’ problems, one of which is the need to acquire two types of batteries: deep cycle and starting battery. The design and capability of the TPPL is ideal to do both tasks – it could crank up the engine and give power to its electric parts. How? TPPL batteries are made of 99.99% lead that is rolled, not casted, and just 1mm thick. Because of its thinness, the current could percolate in and out better, during charge and discharge cycle. It also lessens the chance of generating heat; therefore, it could not damage the plate. Compared to conventional AGM batteries, TPPL batteries have higher cycle life at deep-discharge levels. In fact, it is capable to withstand about 400 charges/discharges.
Using TPPL is also not time consuming as you only need to wait for about 30 minutes to have it fully charged, which is 15 times faster compared to other conventional type of rechargeable batteries.
What makes TPPL best for marine use? It does not spill, and so has the capability to overcome the non-stop movement of the vehicle especially during high waves. It also does not demand maintenance. Additionally, these batteries perform better during cold seasons, doubling its performance when temperature hits -20oC.
Bear in mind that one of the limitations this battery has is that it cannot be used once put upside down; the battery will not work properly if not well-positioned.
TPPL batteries are ideal for several markets, apart from the boat industry. They are also free from any corrosion, therefore, these may also be used on hybrid and electric vehicles, AGVs, floor scrubbers, and so on.
