[quote="threedee";p="3165426"Constant voltage charge (25c) Cycle use 7.2-7.5v Standby use 6.8-6.9v[/quote] Like it says, you need to apply a constant voltage of 7.2 to 7.5 volts (or the lower voltage range for "trickle" standby charging). It might be sensible to start with a lowish voltage e.g. 7v if the battery has been discharged for a long time.
Pulse chargers may work but if your battery is beyond repair just get a new one (you will also get discount by returning old one when buying new). Capacity will also vary, some batteries might
What is the lifespan of a lead-acid battery? The lifespan of a lead-acid battery can vary depending on the quality of the battery and its usage. Generally, a well-maintained lead-acid battery can last between 3 to 5 years. However, factors such as temperature, depth of discharge, and charging habits can all affect the lifespan of the battery.
In one experiment, when the discharge time of a <5-year-old lead-acid battery used for engine starting had degraded to about 50% of its initial discharge capacity, the
