I bought a Shogun NS70L battery (60AH) on 30 Nov 2010, about 2 years ago. I have used bedini charger to charge this battery to test whether the charger can increase the capacity of the new battery since r-charge claimed that the battery capacity can increase more than the battery's original capacity. Well, there is a 39% increase than its initial battery capacity. But I realized my new battery initial capacity was not really up to 60AH capacity after the charging. It is 54AH only. May be Bedini load test is slightly offset.
Now, this battery has just died on Jan 2013 after 2 years. The battery water is below the minimum level. After filling up the battery with water, I charged it with Bedini charger. During the first load test, there is no capacity at all. It has initial charge of 12.6V when it died, but too weak to sustain any load. Now, it has gone through 10 cycles loading. Below is the result. I am getting around 29AH now from 0AH and going for the final charge. Considering this is a dead battery, the result is not that bad. But, it has not reach its initial battery capacity of 54AH as what r-charge is claiming yet. Sometimes, the battery quality depends on the manufacturer and may not perform as what r-charge is claiming.
On Mar 14, after 2 weeks of not starting the engine, the battery cannot start the engine anymore. The rejuvenation effect is not lasting. This is about 1 month use only.
