Newstar 12V 40Ah Long-Life VRLA AGM Battery (NP12-40Ah)
Ideal for
Overview
Larger UPS installations, telecom sites and critical fire systems need high capacity and a battery that won't need replacing every few years. The Newstar 12V 40Ah delivers both. It provides 40Ah at the 10-hour rate with a 10-year design float life (Eurobat 10–12 years "long life"), so you replace it less often and lower the cost of ownership.
Its very low 9 mΩ internal resistance and 400A 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.
Built for uptime, not for the shelf
What the 12V 40Ah means for your site, your project and your team.
Fewer replacements
A 10-year design float life, double a standard 5-year battery, cuts swap-outs and downtime.
High capacity
40Ah at the 10-hour rate, about 21% more than a 12V 33Ah, for larger loads and longer standby.
Handles heavy loads
Very low 9 mΩ internal resistance and 400A peak discharge carry UPS and inverter loads instantly.
Lower cost of ownership
Longer service life means fewer site visits, less labour and less disposal over the system's life.

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 42Ah, 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.
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 charger settings should I use?
For standby use, float charge at 13.50–13.80V at 25°C with a maximum charging current of 12A.
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 mobility scooters, is not covered.
