How to charge a lead acid battery?

A smaller appropriate charger is a better choice. You could add a 2.5A constant current source. You could modify the circuitry. Recommended charging for lead acid batteries - Battery University Chargetek’s charging and equalization - additional information By clicking “Post Your Answer”, you agree to our and acknowledge you have read our .

Can You overcharge a lead acid battery?

Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.

What is a lead acid battery?

Lead acid batteries are actually the most complicated of all the common rechargeable battery types. They have lots of little quirks you have to pay attention to if you want to get the best possible life out of them. However, they do reasonably well in float service and are much cheaper than any lithium or nickel chemistry battery.

How often should a lead acid battery be charged?

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.

Do lead-acid batteries overheat during charging?

As with all other batteries, make sure that they stay cool and don’t overheat during charging. Sealed lead-acid batteries can ensure high peak currents but you should avoid full discharges all the way to zero. The best recommendation is to charge after every use to ensure that a full discharge doesn’t happen accidently.

Should you charge a lead-acid battery with a saturated charge?

We’ve put together a list of all the dos and don’ts to bear in mind when charging and using lead-acid batteries. Apply a saturated charge to prevent sulfation taking place. With this type of battery, you can keep the battery on charge as long as you have the correct float voltage.
