Last week I bought an agm solar battery from leroy Marlin.
Name solarix, brand Xunzel.
Is leroy Marlin brand for all solar accessories.
I will use it to support my agm victronenergy, either separately or in parallel as needed.
It has charging and internal resistance characteristics very similar to the victronenergy and this is good for parallel.
In fact, measuring with a schunt the current was divided almost perfectly (in relation to the capacity).
What do you think of these batteries and this brand?
They are medium quality batteries ... Not at the level of agm rolls or troyan, but not bad either.
The price range is about that of victronenergy agm batteries.
The data sheet is very interesting:
It performs worse in cold weather than victronenergy.
It has performances similar to victronenergy in terms of capacity in relation to the C rate, but victronenergy is slightly higher.
But it has performances of duration in cycles and in years much superior to the agm victronenergy.
100% DOD: unknown victronenergy, xunzel 400 cycles.
80% DOD: victronenergy 400 cycles, xunzel 600 cycles.
50% DOD: victronenergy 600 cycles, xunzel 900 cycles
30% DOD: victronenergy 1500 cycles, xunzel 1300 cycles.
10% DOD: unknown victronenergy, xunzel over 2000 cycles.
Standby use at 20 C°: victronenergy 7/10 years, xunzel 10/14 years.
Basically it appears that these xunzel agm have high DOD performance, similar to victron agm supercycle.
Victronenergy deep cycle AGM years or cycle duration is not exceptional for a solar battery at these price.
Here the two datasheets:
