Robust Industrial Advanced AGM Storage: The Trojan J305-AES
J305-AES 6V batteries provide true deep-cycle performance with extraordinary quality, cycle life, and support for floor machines, electric vehicles, and marine applications. Trojan AES delivers up to 3x the cycle life of standard AGM with high sustained performance. Trojan AES batteries maintain high capacity in extreme deep cycling (up to 100% DoD), in challenging temperatures and partial charging conditions.
Features and Benefits
- Up to 3x longer cycle life than standard AGM. Validated at 1,200 cycles at 100% DoD vs. 400 cycles for AGM.
- Robust performance in extreme temperatures and conditions. Temperature range from -40 °F to 160°F (-40° C to 71° C).
- Tested to withstand partial state of charge, again and again.
- Virtually no maintenance as watering is not required.
- Trojan AES is classified as non-spillable and can be safely mounted horizontally to fit difficult locations. It’s made using 80% recycled materials and is 99% recyclable.
- Designed and manufactured to absorb vibration and shock.
- This VRLA battery is backed by a three-year warranty.
- Charge with existing AGM charger and profiles.
