AGM Batteries: The newer type of sealed nonspillable maintenance free valve regulated battery uses`Absorbed Glass Mats`, or AGM separators between the plates. This is a very fine fiber Boron Silicate glass mat. These type of batteries have all the advantages of gelled batteries, but can take much more abuse. These are also called `starved electrolyte`. Just like gel batteries, AGM batteries will not leak acid if broken.
RA12-120 is a general purpose battery with 10 years design life time in float charging use. As with all Ritar batteries, all RA models are rechargeable, highly efficient, leak proof and maintenance free.
Stable Quality & High Reliability
RITAR battery is well-known for its stable and reliable performance.RITAR batteries are easy to maintain;thus,permitting a safe and proper operation of the equipment that the battery powers.The battery can withstand overcharge,over discharge,vibration,and shock.It is also capable of extended storage
RITAR＇s unique construction and sealing technique guarantees that no electrolyte leakage can occur from the terminals or case of any RITAR battery. This feature insures safe and efficient operation of RITAR batteries in any position. RITAR batteries are classified as ＂Non-Spillable＂ and will meet all requirements of the International Air Transport Association.
During the expected float service life of RITAR batteries, there is no need to check the specific gravity of the electrolyte, or add water. In fact, there is no provision for these maintenance functions.
Low Pressure Venting System
RITAR batteries are equipped with a safe low pressure venting system,which operates from 1 psi to 6 psi.The venting system is designed to release excess gas in the event that the gas pressure rises to a level above the normal rate.Afterwards,the venting system automatically re-seals itself when the gas pressure level returns its normal rate.This feature prevents excessive build up of gas in the batteries. This low pressure venting system, coupled with the extraordinarily high recombination efficiency, make RITAR batteries the safest sealed lead-acid batteries available.
Heavy Duty Grids
The heavy-duty lead calcium-alloy grids in RITAR batteries provide an extra margin of performance and service life in both float and cyclic applications, even in conditions of deep discharge.
Low Self Discharge
Because of the use of Lead Calcium grids alloy, RITAR VRLA battery can be stored for long periods of time without recharge.
