Battery monitor pricing
I understand the need for a battery monitor - certainly the analogy of monitoring your fuel level via a fuel pressure gauge strikes home (although it's a little bit off). I want to get one. What I ...

Phil;
I see no material difference.
Lifeline 5.4 Charging(omitting 6V specs):
Absorption charging stage. A voltage limit of 14.3volts ± 0.1volts should be used when the battery temperature is 77°F(25°C). The battery is fully charged when the current drops below 0.5% of the battery’s rated capacity (0.5A for a 100Ah battery).
Lifeline format with Full River(FR) specs:
Absorption charging stage. A voltage limit of 14.7volts should be used when the battery temperature is 77°F(25°C). The battery is fully charged when the current drops below 0.024% of the battery’s rated capacity (0.024A for a 100AH battery).
FR gives a formula in Figure 1 to calculate the end of Abs; I2 = 0.012 * 0.02 * c20.
0.012 * 0.02 is a constant 0.00024, or 0.024%
On page 2 we find:
The profile in Figure 1 can be used with or without the float stage. Without the float stage, recharge can be terminated based on time (this will need to be determined as it will vary with depth of discharge and charge current) or percentage recharge (~105%-115%)(italics are mine)
So do we now have a definition of fully charged without float?
