Description
The main difference from its predecessor is the cycle life. At 100 % depth of discharge EVH withstands 450 cycles against 400 for EVX, so in daily use the battery keeps its rated capacity longer and is replaced less often. Pure lead plates work in a sealed VRLA-AGM case, the electrolyte is absorbed in a glass separator, and water refilling is not provided. 12 V monoblocks are connected in series up to the traction drive voltage, and parallel branches add capacity. The series complies with IEC 60254-1/2, the dedicated standard for lead traction batteries, and holds UL 1973 (MH66728) and UL 1989 (MH14533) certificates.
How to choose
The life depends strongly on the depth of discharge. If the battery is usually discharged by only a third, both traction series give 1800 cycles at 30 % DoD, and the choice is then determined only by the required capacity. EVH makes sense where almost the entire reserve is used every day. When you need less than 15 or more than 39 Ah, look at EVX with its range of 7.2–75 Ah.

FAQ
How does the EVH battery differ from EVX?
EVH is a development of EVX with a longer cycle life, 450 cycles against 400 at full discharge. The capacity range is narrower, 15–39 Ah instead of 7.2–75 Ah.
How many cycles does the EVH traction battery withstand?
The manufacturer states 450 cycles at 100 % DoD and 1800 cycles at 30 % discharge. Shallow discharge extends the service life several times.
How do I build a traction battery from EVH 12 V monoblocks?
Monoblocks of equal capacity are connected in series up to the drive voltage. For more capacity, parallel branches of identical batteries from the same batch are added.
Does the EVH battery need water refilling?
No, the VRLA-AGM design is maintenance-free and the electrolyte is absorbed in a glass separator. It is enough to monitor the charging mode and the condition of the terminals.
What standards does the EVH series meet?
IEC 60254-1/2 for lead traction batteries, as well as UL 1973 (MH66728) and UL 1989 (MH14533).
