Special Features

Lead-resistant structure
A minimum-required quantity of electrolyte is impregnated into, and retained by, the positive and negative plates and separators; therefore electrolyte does not flow freely. Also, the terminal has a sealed structure secured by long adhesive-embedded paths and by the adoption of strong epoxy adhesives which makes the battery leak-resistant. (Note) In stand-by/back-up uses, if the battery continues to be used beyond the point where discharge duration has decreased to 50% of its initial (i.e. life judgement criteria), cracking of the battery case may occur, resulting in leakage of electrolyte.

Easy maintenance
Unlike conventional batteries in which electrolyte can flow freely, Sealed-Lead Acid batteries do not need the specific-gravity check of electrolyte nor the watering structurally; this makes the battery function fully and makes maintenance easy.

No sulfuric acid mist or gases
Unlike conventional batteries in which electrolyte can flow freely, Sealed-Lead Acid batteries generate no sulfuric acid mist or gases under the usage conditions we recommend. In uses under conditions other than recommended, however, gas generation may occur, therefore do not design the battery housing with a closed structure.
