My supplier has installed Mira HV25 batteries in place of the HV2600's that were originally planned.
The HV25's specification gives a life of >4000 cycles which is less than the >6000 cycles given for the HV2600's.
Does the HV25 have third less expected life? Both are guaranteed for 10 years but would the HV2600 last longer?
Thanks for any help on this.
Mira HV25 expected life
Cycle life is the main factor when reviewing battery life so the 6,000 cycles of the HV2600 is far better than the HV25.
It's important to remember it's age or cycle count whichever comes first so it's not as simply as saying their both 10 yr warranties as the HV25 will expire it's warranty much faster than the HV2600 once the cycle life is used up.
Also worth noting that the batteries won't simply stop at the cycle count, but their performance can't be warrantied anymore.

The latest datasheet for the HV25 now has the cycle life as 6000, and not 4000 which it previously had. I guess it's had more testing?

Yes I noticed this too, this week when I looked at the latest spec sheets - Not sure whether it's better testing or they have changed the battery cells to match the HV2600 so I think you have to assume this is true for the very latest Mira batteries - but the specifications are now 600 cycles, and improved efficiency too.davidiaincraig wrote: ↑Fri Mar 17, 2023 11:24 am The latest datasheet for the HV25 now has the cycle life as 6000, and not 4000 which it previously had.
