Despite the fact that the batteries you receive from us will be almost fully charged the system will still need to complete and finish off a full charge, until this charge has completed you will not have the full runtime protection available, you will find its better to allow the system to run without load to start while it completes the first charge to reset the new battery energy level
Fitted in a UPS you could expect a battery life span of between 2-5 years, how it's used over time however will determine this, do not pile books or files on top of it, it needs good ventilation, batteries will get very hot, if the vents are blocked it will get hotter, the hotter it gets the shorter the life, If you can keep the constant load below 40% the batteries will end up lasting longer, a high load will be at the expense of the overall life expectancy of the cells
These batteries are valve regulated, they are recommended for use in uninterruptible power supplies, they will not leak due to the advanced absorbed glass mat technology, being both AGM and VRLA they can be used in both tower or rack configurations as they can be mounted on the side, also not-hazardous so safe for mission critical installations, busy data centres, medical back up and even the home office
these hot swap capable batteries are recyclable, please ensure they are disposed of at a recycling centre when they have fulfilled their purpose for you, more information about recycling can be found at the foot of this page, check the product code carefully before ordering as many UPS systems have similar ones
