Product details
The EVX1272 is a 12V top terminal Valve Regulated Sealed Lead Acid battery in the CSB EVX series. It utilizes AGM Absorbent Glass Mat technology with a gas recombination efficiency of up to 99%, and features pure lead construction and a proprietary formula. This series is primarily aimed at electric mobility and cyclic energy storage, positioned as durable deep cycle pure lead batteries, and the official application for the EVX1272 is electric mobility.
In terms of capacity, the EVX1272 has a nominal capacity of 7.2Ah, measured at 1.75VPC, 25°C, 20-hour rate. Other rate capacities are also listed: 6.00Ah at 8-hour rate, 1.75VPC, 25°C; 7.20Ah at 20-hour rate, 1.75VPC, 25°C; 5.76Ah at 8-hour rate, 1.80VPC, 25°C. The maximum charge current is 2.16A, the maximum discharge current is 130, the short circuit current is 292A, and the internal resistance is 23.9mΩ.
In terms of dimensions and construction, the battery length is 150.9±2.0mm, width 64.8±1.0mm, height 98.6±1.0mm; weight 2.55kg; terminal type is F2 Faston Tab 250. The case is made of ABS with a flame retardant rating of UL 94-HB. The equalization voltage range is 14.4 to 15.0Vdc (25°C), while the float charge voltage is not provided in the data. Regarding temperature: nominal temperature 25°C, discharge temperature range -15°C to 50°C, charge and storage temperature range -15°C to 40°C.
For cycle performance, at 25°C, 400 cycles can be achieved at 100% depth of discharge; 1800 cycles at 30% depth of discharge. Self-discharge characteristics: after 90 days at 25°C, capacity loss is less than 10%, with a maximum storage period of 6 months; the battery must be fully charged before reuse, and if the storage temperature exceeds 25°C, charging should be advanced accordingly. This product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 certified (MH14533).
Based on the above features, the EVX1272 can be used in electric mobility and deep cycle applications. Its maintenance-free design combined with AGM gas recombination technology effectively reduces routine maintenance requirements. When selecting a model, it is recommended to refer to the capacity and life parameters listed in this article based on the actual discharge rate, ambient temperature, and depth of cycle.
