Yuasa NPL Range

The Yuasa NPL series batteries set the standard for quality and excellence in the field of rechargeable batteries. These high-quality batteries ensure that no electrolyte leakages occur from the case or terminals. The NPL series range are an enhance version of the NP series, almost maintenance-free with the perfectly sealed construction and the recombination of gases within the cell.

Why would you buy an NPL Series Lead-Acid battery?

The NPL series offers a unique electrolyte suspension system incorporating a microfine glass mat (AGM) to retain the maximum amount of electrolyte in the cells. The valve regulated design of this battery is equipped with a safe low-pressure venting system, which releases excess gases and automatically reseals should there be a build-up of gas within the battery due to overcharging.

GEL Vs AGM Lead Acid Batteries

Absorbed Glass Mat

These batteries contain only enough liquid to keep the specially designed glass mat wet. The glass mat is made to wick the battery electrolytes between the battery plates. If the battery is broken no free liquid leaks out.

AGM batteries are preferred when a larger number of amps are required. The life expectancy remains excellent in most cases if they are not discharged more than 60% between recharges and/or recharged fully every 3-6 months.

Gel Cell Batteries

These batteries contain silica type gel, which is a thick paste-like material. It allows the electrons to flow between plates but will not leak in a gel battery if the case is broken.

Gel Cell Batteries don't offer the same power capacity as per the same physical size as AGM batteries. Gel cell batteries excel in slow discharge rates and slightly higher operating temperatures and with excellent deep cycle capability. Recharging these batteries must be done correctly or it will suffer premature failure.

FAQ's

Is a lead Acid Rechargeable Battery Harmful?

Lead-Acid batteries contain chemicals that have the potential to be harmful to both your health and the environment. They contain lead which is a highly toxic metal and sulfuric acid which is a corrosive electrolyte solution. Proper handling procedures must be followed always.

What state of charge will the battery be in when delivered?

The NPL Range will have 90% to 95% of charge approximately, we do recommend charging prior to use.

How to dispose of Lead Acid Batteries?

Lead acid batteries do contain hazardous chemicals, so recycling is the only way to dispose of them.

Recycle responsibly. A wide range of schemes are available.

Note

These batteries should be charged with a constant voltage charger at 2.3V per cell standby and 2.5V per cell with a current limit of 0.25 x capacity (Ah) for cyclic applications (max 20 hour charging).

Warning

Do not charge in a sealed enclosure
