IEI charging is a very popular charging method for lead acid batteries. What you want to avoid is heat and gassing. I found through experimenting that a battery will take in almost as much current as it can put out, so if you have a low internal resistance battery high current is appropriate.
A good rule of thumb is you can charge a lead acid battery at any current [highlighted by me. Nick] you want until the battery reaches 13.8 volts Manufacturers of deep cycle batteries almost always prescribe the initial charge current of no more than 0.3C.
I really sometimes mix amp and amp hours The usual rule for charging a flooded lead-acid battery is that the charge current should be less than 20 - 25% of the Ah rating. for your 4 Ah (4000 mAh) battery,. that would mean a maximum charge rate of about 1 Amp. Gel and AGM batteries can accept a higher charge rate.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.
Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
Customers often ask us about the ideal charging current for recharging our AGM sealed lead acid batteries. We have the answer: 25% of the battery capacity. The battery capacity is indicated by Ah (Ampere Hour). For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah.
