That aspect of the charger has no effect on battery life. It's stated so that the duty cycle of the charger isn't exceeded and even that is unlikely if it never has to charge totally discharged batteries. The worst that could happen is that the life of the charger is shortened.Don't think lots of people realise that most vans only come with chargers capable of only charging approx 120 to 180 amps of batteries yet stick 200/300 plus of batteries onto there systems then wonder why they don't get a full life out of batteries.
Last Hymer the AGM's lasted 18 months, they wouldn't honor the warranty because they tested OK on a CCA test which is a starter battery test totally pointless on a leisure battery. Replaced them with Gels.I'm sure @Lenny HB will give his experiences!
Check your first statement Lenny It's not what I expected from you.Last Hymer the Gels lasted 18 months, they wouldn't honor the warranty because they tested OK on a CCA test which is a starter battery test totally pointless on a leisure battery. Replaced them with Gels.
In my current van I got rid of the AGM and fitted 3 Gels, Gels are probably one of the most reliable batteries they can be discharged lower to 80% DOD, they last a long time 6-10years is quite common. The only downside is they take longer to fully charge and you need a charger with a Gel setting.
You were lucky punk.I have had 6-8 years out of my last AGM's. going Lithium next time.
How many AGM equipped vans are running around with a faulty charger?Agreed in principle Tony but if the charger is damaged and not giving full charge to batteries they then " suffer " and premiture failure occurs. Yes even a small 8 amp charger will eventually charge batteries but people often neglect to even check batteries simple fluid levels check are seldom made ....all add to shorten life
When you say ‘booster’ are you talking about a B2B or something else?When I got my Hymer the first mod was to replace the Varta AGM with a Super-B Epsilon. Exact same fitting, done in 30 minutes including setting the booster to Lithium and the EBL to Gel since it was that or AGM. The Epsilon is perhaps the only Lithium out there seriously engineered as a lead replacement.
It is « only » 90Ah and last Monday when we took off around noon after stopping the day before around 6PM, it was down to 78%. The booster charged it at 57 amps until it reached 97% and then it slowed down gradually. It was back to 100% in less then 25 minutes.
Pretty expensive battery, but considering that such charging speed from the alternator makes solar totally redundant for us, not a bad deal all in all given the convenience. And total weight is 12.5 kgs.
