RITAR batteries are well known for their stable and reliable performance. They 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.

The unique construction and sealing technique guarantees that no electrolyte leakage can occur from the terminals or case of any battery. This feature insures safe and efficient operation of the batteries in any position. The 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.

The 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.

Ritar Power specialise in sealed lead acid and gel batteries. Covering a wide array of applications they have a heritage of research and development which has lead to developing high quality products. Through constant innovation they have engineered production lines which minimise any environmental impact. Using high quality materials and state of the art construction practices, Ritar Power manufacture batteries with proven performance in extreme operating conditions.

Please note: These batteries come with 5 years nationwide warranty.
