The reason that I gave 2 stars is that the batteries came with very low voltages. This low voltage can be an indication of an early life failure. The lowest voltage was 7.2 volts. On a 12 volt battery, this is not good.I installed them in to the UPS and they seem to have charged up ok. I would have preferred that they had been swapped out but the solutions offered were not conducive to this action.
Very prompt delivery. Fixing screws included, a nice touch. Can't, of course, comment on longevity of batteries yet.
Great value when you need to rebuilt your UPS battery - much cheaper than the pre-built and just as good These loose batteries replace those that are pre-assembled for your specific UPS. You'll need to take and reuse some parts from the originals - the connectors, the block-style fuse and the terminal covers, then use double-sided tape to join the batteries together. Since that is the construction method of the originals then it seems quite good enough. You'll need the appropriate spanner, a cross-head screwdriver, the double side tape and about 30 minutes to do the whole job. Simple. Quick. Cost-effective.
