A couple of years ago, the electrolyte density dropped quite a bit on one cell and the hoppecke guy said to boil the batteries a few times. This did the trick in the short term. The density was pretty even across all 24 cells. Since the pandemic, the hoppecke service no longer exists, hence my...

Yes, I do boil them every now and again. The charging voltages are as per the Victron standards. I recently dropped the voltage by one volt as they needed topping up every 2 weeks. They've been noisy since they were new.

They are in the loft. Currently at 24ºC. I'm using all Victron kit (mppts) with the recommended voltages. I'm thinking of replacing the la with lithium (6 x 3.5kWh). Although the capacity will be less, at least it will be usable. What upsets me is that everyone says the la batteries should last...

Hello all. I have a bank of 24 Hoppecke 910ah 2v batteries. As soon as they start to discharge, the voltage drops to 45. A few kW of load will soon drag that down to 43 and then the inverter shuts down (Victron). I just went up into the loft to check electrolyte levels and see that about half of...
