6 FAQs about [Is it good to use lead-acid batteries in parallel ]
Can a lead acid battery be connected in parallel?
In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.
Can a lead acid battery be voltage charged?
Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage.
Do you need a fuse for a lead acid battery?
In actual practice, people put lead acid batteries in parallel and cycle them that way frequently. Just look at RV's and boats and off-grid installations. A fuse for each battery would not be a bad idea. If you are charging them all anyway then what does it matter if one discharges into another?
What happens if a lead acid battery goes bad?
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.
Why are lead acid batteries treated as a unit?
Normally we treat the cells in a 4 or higher voltage lead acid battery as a unit because the internal series connections usually makes them age, charge and discharge in a similar fashion because the usual limits of differences between cell (internal resistance) are usually smaller than the total load external resistance.
Should I remove a lead acid battery?
However, if your existing battery has significant self-discharge, you are best to remove it. 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.
