Features include:-

Design that allows a device with life expectancy of about 15 years.
The expected life in floating charge is about 15 years (when discharged with 0.25CA current at ambient temperature of 25c), which is three to five times longer than the conventional batteries (NP series).

The battery is economical.
As a result of having realized 3-5 times longer life than our conventional batteries (NP Series), running cost becomes reduced considerably

Flat top design.
The battery shape incorporates a flat top design. It also employs an integrated handle opening structure (REL-B24-12, 38-12 and 65-12) which facilitates battery installation and movement.

Flame-retardant material.
Battery container and lid use flame-retardant material (certified by UL94 , with V-O oxygen index of more than 31)

Interchangeability with conventional batteries.
The batteries have interchangeability in outline dimensions and terminal positions with our NP series
batteries (* NOTE: REL-B24-12 is 50mm longer than NP24-12 in height, and REL- B38-12 is 5mm longer than NP38-12 in height)
