About 10 amps per hour is the general safe charging rate for most lead acid batteries. Higher charge rates may be possible in some cases, but it is crucial to consult the manufacturer before attempting to charge a lead-acid battery at a faster rate. How Long Does It Take to Charge a Dead Lead Acid Battery?
Lead-acid batteries are popular for their performance and reliability. To charge a lead acid battery, there are two main methods: series and parallel. The method you choose depends on the number of batteries you have and the voltage you need to charge them at.
Lead acid batteries must always be stored in a charged state. A topping charge should be applied every six months to prevent the voltage from dropping below 2.10V/ cell. With AGM, these requirements can be somewhat relaxed.
Lead acid batteries are strings of 2 volt cells connected in series, commonly 2, 3, 4 or 6 cells per battery. Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently.
To charge a 12V flooded lead acid battery, you should use 2.40-2.45 volts per cell as the charging voltage. This will ensure the fastest charge without damaging the battery.
Lead acid batteries have some disadvantages, one of which is their long charging time. It can take 8 to 16 hours to fully charge a lead acid battery, depending on the size of the battery and the charging current.
