All batteries eventually need replacing as the charge capacity slowly decreases over time. We recommended to perform maintenance on your SLA batteries once every six months to ensure they're still functioning properly. For How Long Should I Charge my Battery? One common question regarding charging SLA batteries is for how long you have to charge them. There is a simple formula you can use to get an estimate of the needed charging time. Multiplying the amperage of the battery by 1.3 and then dividing the total by the amperage of the charger will give you the hours for which you have to charge the battery, assuming it was completely discharged.
