The batteries that you receive from us will be almost fully charged but the system will still need to complete a service charge after installation, of course while this charge going on your UPS will not be in a position to offer the full runtime protection until its finished this, we know the system is probably urgently being used but if you can its best to run without a load to start so it can complete the job and reset itself to the new energy level

You can assume that battery life in the UPS would be between 2-5 years, how it's used over time however will determine this, make sure the vents are not restricted it must have good ventilation, the batteries will get hot in general use, if they are allowed to run hot all of the time it will shorten life span, 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
