Ups battery replacement
In early 2005 I found a couple of cheap Inform UPS battery backup units for my servers. They worked great and did they're simple switching job well when the power went out. Fast forward a few years to 2008 and the situation is different, one of the units no longer can hand half of it's capacity. I quickly figured it was the battery and swapped it out for a new 12v 7.2 Ah sealed maintenance-free lead battery.
Inform 600AP
The UPS is rated for AC 220V 50/60 Hz input and 350 W / 600 VA, 50/60 Hz, AC 220V output.
Opening case
Removing four screws will release the top casing.
Removing battery
The battery is located on the front, the circuitry in the top casing, and the inverter behind the battery.
The battery is easily removed by unmounting the front-panel and disconnecting the positive and negative leads.
CGB manufacturered the original battery unit, model CB1270, a regular 12v 7.0 Ah SLA battery.
New battery
I looked for a suitable replacement battery and I found two local suppliers, both offering the same amperage but slight price difference. I tried the cheaper option to experiment how much load and how durable the battery is.
To install the new battery was a simple matter of sliding the battery in place and connecting the leads.
