Newstar 12V 55Ah Long-Life VRLA AGM Battery (33-5512)
Ideal for
Overview
Larger UPS installations, telecom sites and central emergency lighting systems need high capacity that holds up year after year. The Newstar 12V 55Ah delivers 55Ah at the 10-hour rate with a 10-year design float life (Eurobat 10–12 years "long life"). It supports bigger loads and longer runtimes while keeping replacement cycles long.
Its very low 6.5 mΩ internal resistance and 550A maximum discharge current carry heavy UPS and inverter loads the moment the mains drops. M6 threaded-insert terminals give a secure, low-resistance connection. Its sealed AGM construction means no water top-ups and no routine checks. BAM supplies it wholesale to integrators, UPS and telecom contractors, MEP contractors and FM companies across the UAE and GCC.

Frequently asked questions
Can't find your answer? Message our sales team on WhatsApp.
Why is the capacity rated at 10 hours, not 20?
Long-life batteries are usually rated at the 10-hour rate. At the 20-hour rate, this battery's discharge data shows about 59Ah, so compare like for like when checking other brands.
What does a 10-year design life mean?
Under float charge at 25°C, the battery is designed to give 10 years of service before it reaches end of life. Eurobat classifies it as 10–12 years, long life.
How long will it last in the Gulf?
Heat shortens battery life. For the longest service, install it in a cooled, ventilated room. Every 10°C above 25°C significantly reduces float life.
Will it fit my cabinet?
It measures 230 x 138 mm and is 215 mm tall including terminals, and weighs about 17.3 kg. Check shelf space and load rating before ordering.
Which terminal does it have?
It comes with T14 terminals: an M6 threaded insert that takes an M6 bolt. Check your cable lugs suit M6 before ordering.
What does the warranty cover?
Standby (backup) use only, where the battery sits on float charge and discharges during power failures. Cyclic use, such as solar, golf carts or daily-cycling inverters, is not covered.
