• IBM 90P4831 battery replacement

The batteries that we dispatch to you will be almost fully charged, your UPS will complete a full charge and this helps it reset to the new battery cell, you should note that while this is going on the system will of course not be able to offer the full runtime backup time period until it has finished doing this, our best advice would be to allow the system to run without load during the first charge to allow the new battery energy level to reset

A fair assumption of battery life in a UPS is between two to five years, this will though vary greatly on the general conditions, supplying adequate ventilation is important, the batteries are being continuously used 24/7 the hotter they are allowed to get the shorter the life expectancy, try and keep the constant load below 40%, while it may well be capable of much more it will shorten the battery life so it's a balancing act

The battery type is the preferred AGM or absorbed glass mat construction, they are also valve regulated, this means they can be used in tower or rack mounted UPS systems without the fear of any leakage, they will require no maintenance throughout their entire life span and they are not-hazardous deemed safe for use in busy data centres, medical back up and of course the general home office
