They become more resistive as they are filled. A smart charger can completely fill a Lead Acid battery over time, far better than a split charger, as it uses different stages of charging. So with Lead Acid, a smart charger is used to keep the battery full. Adding a larger smart charger won''t necessarily charge a Lead Acid battery faster.
To overcome the problem of sulfation in lead-acid batteries, we prepared few-layer graphene (FLG) as a conductive additive in negative electrodes for lead-acid batteries. The FLG was derived from synthetic graphite through liquid-phase delamination.

Conversely, charging lead acid batteries is like steering a ship. You need time to get them headed in the right direction. Thrash about too much and Peukert''s exponent will rob you of great wads of efficiency.. Lead-acid likes to be cared for, with currents kept modest and sustained equalisation charges to balance them up every fortnight.
