Where This Battery Is Used
- 48V telecom reserve strings - four 12AVR145ET blocks in series behind a rectifier plant, sized off the 8-hour rate.
- Outdoor cabinets and remote huts - front-access service where the cabinet door is the only way in.
- Long-duration UPS float - installs specified in ampere-hours rather than the watts-per-cell figure of the High Rate series.

Frequently Asked Questions
Which Unigy I warranty tier does the 12AVR145ET fall in?
The upper tier, at 4 years. East Penn's Form 0985 sets the tier by two tests, capacity of 100 ampere-hours or more at the 8-hour rate and a front-access terminal, and the 12AVR145ET passes both. The tier does not follow the model number, which is why a smaller top-terminal Unigy I block can carry a shorter term than this one. The figure applies at 77°F, and the full terms travel with your written quote.
How long will a 12AVR145ET string carry a load?
It depends on the load, so read it off the discharge table. Each block delivers 18.1 amps for eight hours, 26.3 amps for five hours, or 93.9 amps for one hour, all to 1.75 volts per cell at 77°F. Divide your plant's DC load by the string voltage to get amps per string, match that to the table, and you have the reserve time per string. Send the load and the required reserve and a specialist sizes the string count for you.
What is GR-4228-CORE?
Telcordia's generic requirements document for valve-regulated lead acid batteries in telecommunications plant. It covers the tests and documentation a telecom operator expects a stationary VRLA battery to meet before it goes into a central office or cabinet. East Penn states the 12AVR145ET is designed to meet it, alongside IEEE recommended practices and UL 1973, which covers the compliance file most carrier and installer specifications ask for.
12AVR145ET or 12AVR150ET?
Both are front-access Unigy I blocks on the same 4-year tier with the same 10-year design life, so the choice is capacity. The 12AVR150ET adds 5 ampere-hours at the 8-hour rate. If your reserve calculation lands close to 145 Ah, price both and let the freight and shelf fit decide; if the plant standard already names one of the two, match it so the string stays uniform.
