Technical Features:

Sealed Construction Shimastu’s unique construction and sealing technique ensures no electrolyte leakage from case or terminals.

Electrolyte Suspension System,Besides 6 volt battery for ride on toys,all other NP series batteries utilize Shimastu’s unique electrolyte suspension system incorporating a microfine glass mat to retain the maximum amount of electrolyte in the cells. Theelectrolyte is retained in the separator material and there is no free electrolyte to escape from the cells. No gels or other contaminants are added.

Control of Gas Generation The design of Shimastu’s NP batteries incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use.

Low Maintenance Operation Due to the perfectly sealed construction and the recombination of gasses within the cell, the battery is almost maintenance free.

Terminals NP batteries are manufactured using a range of terminals which vary in size and type. Please refer to details as shown.

Operation in any Orientation The combination of sealed construction and Shimastu’s unique electrolyte suspension system allows operation in any orientation, with no loss of performance or fear of electrolyte leakage. (Excluding continuous use inverted)

Valve Regulated Design The batteries are equipped with a simple, safe low pressure venting system which releases excess gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge. Note. On no account should the battery be charged in a sealed container.

Lead Calcium Grids The heavy duty lead calcium alloy grids provide an extra margin of performance and life in both cyclic and float applications and give unparalleled recovery from deep discharge.

Long Cycle Service Life Depending upon the average depth of discharge, over a thousand discharge/charge cycles can be expected.

Float Service Life The expected service life is five years in float standby applications.

Separators The use of the special separator material provides a very efficient insulation between plates preventing inter-plate short circuits and prohibiting the shedding of active materials.

Long shelf Life The extremely low self discharge rate allows the battery to be stored for extended periods up to one year at normal ambient temperatures with no permanent loss of capacity.

Operating Temperature Range The batteries can be used over a broad temperature range permitting considerable flexibility in system design and location.

* Charge – 15°C to 50°C

* Discharge – 20°C to 60°C

* Storage – 20°C to 50°C (fully chargedbattery)
