WAFFLEBOARD PREFERRED* (MINIMIZES POTENTIAL FOR POST PENETRATION AND SHORT CIRCUIT) BATTERIES following. With the CCCV method, lead acid batteries are charged in three stages, which are [1] constant-current charge, [2] topping charge and [3] float charge. [pdf]
Following are some tips to be followed while charging Lead Acid Battery: Always keep the battery in a well ventilated space. Do not keep any inflammable liquid like Petrol near the battery. The charger should be plugged in to the AC socket only after it is connected to the battery. Observe the battery while charging.
The charge current for small lead-acid batteries should be set between 10% and 30% of the rated capacity (30% of a 2Ah battery would be 600mA). Larger batteries, such as those used in the automotive industry, are generally charged at lower current ratings.
Lead acid batteries must have a layer cardboard separating each level. This includes a layer of cardboard on the bottom and the top of the load. Typical Pallet Weight (for 3 layers): Between 2800 and 3300 lbs – Pallets are not to exceed 3300 lbs. Only lead-acid batteries may be packaged: No mixing in other batteries or recyclables.
Temperature Control: Ideally, lead-acid batteries should be charged at temperatures below 80°F (27°C). Charging at high temperatures can lead to thermal runaway, where the battery overheats and becomes damaged. If your battery becomes hot to the touch during charging, stop the process immediately and allow it to cool. 4. Avoiding Overcharging
Proper storage is essential for maintaining the health of lead-acid batteries, particularly when they are not in use for extended periods. Store Fully Charged: Always store lead-acid batteries fully charged. If a battery is stored in a partially discharged state, sulfation can occur, which will permanently reduce the battery’s capacity.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

There are no direct interchangeable alternatives for group 4 battery if we speak about dimensions, but if your battery space hasn't strict limits, you can choose a little bigger or smaller. . If you need 12 Volts, you can connect two group 4 batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries. If one 6V lead-acid battery is connected. . If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group 4 batteries are in parallel, their voltage is equal to the voltage of one. [pdf]
Each vehicle model has a designated battery group size, which refers to the physical dimensions and terminal configuration. For example, the Battery Council International (BCI) provides a standardized list of battery group sizes for compatibility. Using the correct group size ensures optimal performance and fit.
According to the U.S. Department of Energy, more than 300 million vehicles in the U.S. rely on specific battery group sizes, with the number expected to increase with vehicle ownership trends. Battery group size affects multiple areas, including vehicle safety, reliability, and performance.
Inspect the existing battery for its group size: Inspecting the existing battery is a straightforward method to determine your vehicle’s required battery group size. Batteries have a label that shows their group size. This is usually a three-digit number, such as 24 or 75.
The battery group size for your car depends on its make, model, and engine type. Check your owner’s manual or your current battery label for specifics. Common group sizes include 41, 42, 47, 48, and 49. Ensure the new battery fits properly to avoid movement or damage. You can also consult your dealership for assistance.
Smaller batteries can have less capacity, performance, and power in comparison with 4 group. Bigger batteries can have more capacity and power compared to 4 batteries. If you need 12 Volts, you can connect two group 4 batteries in series to double the voltage.
When group 4 batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities. If you have two 6V lead-acid batteries with 30 Ah capacity and you connect them in parallel, you'll get 6 Volts with 60 Ah.
