Product Details

High Rate REW Series

The high performance Yuasa NPW45-12 battery is specially designed for applications requiring high rate discharge. The high quality rechargeable sealed lead acid battery ensures that no electrolyte leakages occurs from the case or terminals. This battery is almost maintenance free with the perfectly sealed construction and the recombination of gases within the cell. 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.
The NPW45-12 battery uses a unique electrolyte suspension system incorporating a microfine glass mat (AGM) to retain the maximum amount of electrolyte in the cells.

FAQ's

GEL Vs AGM Lead Acid Batteries

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 AGM battery is broken no free liquid leaks out.

AGM batteries are preferred when a large amount 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 contains 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 do 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 a premature failure.

Are Lead Acid Rechargeable Batteries 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 at all times.

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

The Y7-12 will have 90% to 95% of charge approximately, we do recommend charging prior to use.

Warning

  • Do not charge in a sealed enclosure!
