Bang, Buck, Batteries
Getting ready to repower a coach- 6 of them for 750 amp hours at 12 volts.

Blinking red light. That one put me me on the floor, howling...
You gots your infra-red (IR) digital pyrometer
You gots your gray matter t'ween your ears
Connect them visually
Then monitor the temperature incline of your terminals as the battery charges.
Start with the manufacturer's specs for maximum charge rate
Factor in differential temperature to ambient (Delta T). Remember an ambient temp of 0c skews the factor tremendously. Cold electrolyte reluctance, versus a higher BTU loss. You get the idea. When doing that note the battery temp that allows the highest controlled voltage amperage. Example 62F.
Wuuwee, this means at a given voltage the battery will accept "X" amperage at "X" degrees F or C.
But the key is the rate of voltage rise. When it reaches so many degrees (fractions thereof) per minute, then that should be the limit regardless of other factors.
Such an effort is absolutely contradictory to mixing martinis, and discussing import stuff like politics and movie stars, but nevertheless it is interesting to some folks.
