Product details
As a member of the EVX series, the CSB EVX12170 is a 12V top-terminal valve-regulated sealed lead-acid battery built with a pure lead construction and AGM technology, positioned by the manufacturer as a long-life deep-cycle battery for electric mobility and cyclic energy storage needs. In terms of capacity, the nominal rating is 17Ah (measured at 25°C and 1.75VPC at the 20-hour rate); at the 8-hour rate, it is 14.48Ah (1.75VPC @25°C) or 14.00Ah (1.80VPC @25°C).
Electrically, the short-circuit current reaches 536A and internal resistance is only 13.3mΩ; the maximum discharge current is 230A, and the maximum charge current is 5.10A. The equalization voltage at 25°C ranges from 14.4 to 15.0Vdc/battery, while the float voltage is not found in the data. Regarding self-discharge, capacity loss is less than 10% after 90 days at 25°C; storage is possible for up to 6 months at 25°C, but a full charge is required before use. If the storage temperature exceeds 25°C, recharging should be performed correspondingly sooner.
Structurally, the case is made of ABS material (UL 94-HB), and terminal types include B1/B1B/B3, compatible with M5 bolts; tightening torque must be controlled at 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. Dimensions are: length 181.0±2.0mm, width 76.2±1.0mm, height 167.0±2.0mm, with an overall weight of 5.67kg (12.50 lb.).
In terms of temperature adaptability, the nominal temperature is 25°C (77°F); the allowable discharge range is -15°C to 50°C (5°F to 122°F), while charging and storage are between -15°C and 40°C (5°F to 104°F). Cycle life at 25°C reaches 400 cycles at 100%DOD and increases to 1800 cycles at 30%DOD.
This battery features a valve-regulated sealed lead-acid (VRLA) design and is maintenance-free; its AGM technology achieves gas recombination efficiency of up to 99%, and it is manufactured in accordance with IEC 60254-1:2005, IEC 60254-2:2008, and UL1989 Recognized (MH14533), making it suitable for electric mobility or deep-cycle applications.
