I am looking to go off-grid partially with Solar Power. I already have a 3 year old 160AH lead acid battery hooked up to an 1KW inverter which keeps my house powered partially during power outages which are quite frequent where I live. My battery still seems to be working as good as new despite its age.

Charging Lead-Acid batteries in parallel is not a problem, but a larger battery charger that feeds up to 6A, when equally divided by your 3 batteries of 9Ah, would give 2A/battery, in the best case. Sealed-LA batteries maximum charging current usually is 10-20% of rated capacity. For a 9Ah, I_max = 1A ~ 2A.

how do you determine how many batteries, or series of batteries (lead acid in this case), in parallel a charge controller can safely charge? i''ve read that for lead acid charge current should be 0.05C but that quality chargers can greatly exceed this in the bulk charging stage
Victron super cycle batteries appear to be the best bang for the buck and a good middle ground between lithium and lead acid/agm. They are agm batteries, but they can be discharged 80% safely, they charge faster, they are more energy dense compared to regular agm/lead acid. For a lead acid battery you can''t discharge more than 50%.

AGM, or Absorbent Glass Mat, batteries are a type of sealed lead-acid battery that uses a fiberglass mat to absorb and hold the electrolyte solution. This design makes AGM batteries spill-proof and maintenance-free, perfect for various applications like marine, RVs, solar power systems, and more.
Connecting two amp hour batteries in parallel Two batteries connected in parallel. To calculate the output when wiring in parallel add the Ah ratings together. In this case 4.5 Ah + 4.5 Ah = 9 Ah. The voltage does not change. Note the way the appliance is connected. Many sources explaining parallel wiring suggest the following instead:
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery.

One of the failure modes of Lead-Acid batteries is that one or more cells can develop internal short circuit paths that result in varying amounts of self-discharge current. If your existing battery maintains its voltage above 12.5 Vdc for a week or more while sitting disconnected from anything else, it should be good.
For instance, most 100Ah LiFePO4 batteries have a recommended max continuous charge rate of 50 amps, and most 100Ah lead acid batteries have a …
Don''t get lost now. Remember, electricity flows through parallel or series connections as if it were a single battery. It can''t tell the difference. Therefore, you can parallel two sets of batteries that are in series to create a series-parallel setup. Creating a series-parallel battery bank: Step 1 - Series First
Inspect the battery terminals and cables periodically for signs of corrosion or damage, which could affect performance. Safety Tips. Always wear protective gear, such as gloves and safety glasses, when working with batteries. Ensure the area is well-ventilated, particularly when charging lead-acid batteries.

If a large battery bank is needed, we do not recommend that you construct the battery bank out of numerous series/parallel 12V lead acid batteries. The maximum is at around 3 (or 4) …
Mixing different battery chemistries, such as lead-acid and lithium-ion batteries, is not recommended. Each battery chemistry has specific charging and discharging characteristics that may not align well together. It is best to use batteries of the same chemistry in a series or parallel connection.
When asked how to charge lead acid batteries in parallel people commonly reply connect the positive to positive and negative to negative. Yep, electrically speaking that works. But what if you have an RV, for example, and need to add 3 or 4 or 8 batteries in parallel? Do you continue to add to the string in a linear fashion (Figure 1)?
