    Default Lifetime of Victron batteries

    Hi everyone,

    Last year in Feb the 4 x Deltec batteries that I installed with my 5kVA inverter in 2015 finally started dying.

    I then bought 4 x Victron Gel 12V-110Ah batteries, which have been perfect until now, when suddenly I started getting Low Battery Voltage alarms barely an hour into loadshedding, and with only a load of 200-300W.

    Surely these batteries should be lasting a lot longer than this? The claimed lifetime is 7 years, so did I waste R16K last year?

    Should I just bite the bullet and go LiIo?

    Check with a Victron dealer re. the warranty and/or why it is happening.

    At the very least you will know why it happened IF it is not a warranty claim.

    EDIT: IF you have to replace, go LifePo4 yes ... if you can get one where the BMS interfaces with the Venus/Venus Rpi, then that's the way to go in my opinion.

    I've contacted the shop from where I bought them, let's see what they say.

    Check the cycle graph on your Victron spec sheet, I would be surprised if you get 2years out of them if they are the same I looked at - very poor batteries

    Cannot comment.

    Me, I'm all for DIY LifePo4 banks. Putting one together of 18 x 280ah A grade EVE cells running at 3.4v per cell = +-17kwh bank for like < R55k at current R/$ and shipping rates.

    Now I know all the brand names have 10 year warranties, or cycles, whichever comes first, but as I've experienced with Tenesol panel 25 year warranty and a Duratherm 10 year warranty, if the company closes or the warranty terms are changed the warranty one bought originally is null and void.

    Therefor I'm prepared to take my chances by going DIY.

    FreedomWon has been in business for a long time with a solid reputation.

    The owner even converted his Jeep to electric and drove it up Sani pass as a marketing stunt years ago.

    TT way is the best for DIY`er tinklers, but if you want to install and forget the commercial solutions are the way to go.

    Pisses me off to no end that the shop recommended these to me, if that is indeed the case.

    The original Deltec Betta batteries I had were placed outside, and lasted 5 years

    I would investigate further.

    - Check for bad connections.
    - Measure the battery voltage with an external meter when the alarm comes up. Measure all 4 batteries.
    - Check what the setting is on your inverter for a low voltage alarm.
    - Check ALL the battery related setting on the inverter. There are a heap of them.

    If I am correct Delta Betta were Lead Crystals. ?? Confirm.

    People just all to often assume "the battery is dead/faulty/rubbish/etc". Often there is an underlying problem/s.

    1. Connections are fine - it's a static setup, nothing moves around there
    2. Will do so tomorrow after I go buy a multimeter (what's a good brand?)
    3. Set to 42V, can't change it
    4. It's set to the correct AGM settings
    5. Yes, the Deltec Betta were Lead Crystals, but you can't get them any more.

    Hopefully one battery is on the way out and that's affecting the net voltage and hence short runtime. 1yr 4 months of moderate useage would be very poor, what warranty are they sold with?

    For 2.

    For your purposes even the cheapest one will measure anything below 60 V fairly accurately and safely.

    Mayor tech and Uni T and good enough for house work.

    Professionals will buy Fluke .

    Also remember that the cold temperatures are also not kind to batteries. Not as bad as what you experiencing but it's also a factor.

    At 50% DOD these Victron batteries are rated for 500 cycles. Which is comparable to a second-hand Royal battery

    This shows the difference between life of the battery and the actual claimed cycles at the DOD applied.

    these are some of the stats after 2 hours of loadshedding (6am-8am), at around 1/3 of the usual load since we were sleeping:

    The voltage at 12.5V per battery still seems good although it was under low load.
    Are you sure you have checked that you cannot increase the cut off voltage to about 47V. Better not to discharge down to 42V.
    This could be part of the reason why they only lasted 16 months.

    A little of topic, but that's a very small bank for a 5Kva inverter.

    I have 3Kva and my bank is double yours which is just within acceptable specs.

    This is fine though, if you only do small loads like you said, around 300 - 500 watts.

    Are you very sure that there is nothing else with a higher watts kicking in at times which could've damaged one or some of the batteries?
