| Two times better cycling capability | |
| Improved vibration resistance | |
| Withstands higher electrical loads | |
| Better charge acceptance | |
| Resistance to Deep discharge | |
| Suitable for start-stop applications | |
AGM battery
Advantages | Disadvantages |
| Up to twice longer life than SLI batteries | Higher price than SLI & EFB batteries |
| Three times better cycling capability | |
| High resistance to vibration | |
| Withstands high electrical loads | |
| High charge acceptance | |
| No acid loss and leakage | |
| Designed for harsh conditions | |
| Ideal for start-stop applications | |
What is the classification of SMF55018 batteries, please?
Is it SLI or EFB or AGM
SMF series are SLI type. This type has a variety of applications as a starter battery, but not recommended for Start-Stop engines.
We are really appreciated. please do not hesitate to contact us for any further information.
What is the number of charge-discharge cycles for a Suzuki SLI 50AH battery when 60% of its capacity is discharged
Dear Bashar,
Wish you happy new year. Routine International or Regional standards for testing SLI battery (Such as IEC 60095-1) or Automobile manufacturer’s standards (such as PSA B25 5210), Emphasis on 25% DOD endurance (when 25% of battery capacity is discharged). Ambient temperature in these tests, usually vary from 25 to 40 Degrees Celsius. However, our conventional batteries (SLI) are capable to pass >192 cycles.
We very appreciate you as a punctilious user.
Please be in touch, for any further information.
