Not sure if its just my lawn getting thicker or if the power fell off quickly but it seems like the first 2-3 times I used this it was able to do a lot more than it has since. It does seem to perform better in hot weather than my other batteries. When my OEM batteries get hot I have to let them cool off before I recharge them because otherwise they go straight to "full" (ie stop accepting current). With the Energup I can run it down and put it right on the charger, no issue. I feel like the overall value propitiation is a push - its a little less good for a little less money. If it were a more significant discount to the OEM it would be nicer. I needed 3/4 of a battery (more) to get through all of my lawn in one sitting. This is 3/4 of a battery for 3/4 of the price.
