Found this thread yesterday on this subject because I was confused about equalization and finishing voltage. Mentions US batteries. Don't rely on voltage as your only method of checking the charge level. A stratified battery can give a false high voltage reading while being undercharged. If left for long this will cause the dreaded sulfation. I have been concerned about undercharging too and now I know my chargers are all undercharging because I have started checking the gravity. It is pretty hard to overcharge lead acid but easy to undercharge if you are too timid. Marcus Sabathil Home: 604-947-0800 Mobile: 604-374-1969 Site Q-39, 720 Gardner Lane. Bowen Island BC. V0N 1G0 |
