The rate of charge. Amp is an abbreviation of ampere-hour, a unit of electric charge.
The charge rate should be based on the size or capacity of the battery
to be charged. A 2 amp rate is appropriate for smaller batteries as
used for motorcycles, lawn tractors and so on. 8, 10 & 12 amp rates
are suited for automotive sized batteries.
Faster charge rates than recommended reduce charging time but
lead to increased heat which can warp components or possibly rupture
the battery case. I do not well understand the issue with lower charge
rates but I believe it can be detrimental over the long term.
I'd like to mention the Schumacher SC1200A
After using a series of fixed output chargers over the years, I switched
to the 1200A. It has performed well and has kept my current ACDelco
battery alive long beyond the time that previous batteries needed
The 1200A is one of the chargers that uses a variable voltage charging
approach. Initial charge voltage is relatively high, then it tapers back
as charge level increase, finally charging shuts off. This charger also
offers settings for lead-acid, glass-matt (AGM), gel cell and deep-cycle
batteries. This lets me use it on the ACDelco, on a Yellow-Top Optima
and on some instrument gel-cells I have.
