Will not charge past 50% and holds little charge. I have used a good many of these over the last 20 years under different labels and been entirely happy with the brand and the type, so this review is about one particular dud unit bought recently, NB I am still using one that is over seven years old which is admittedly tired, but in better health than this one. I will update this review when I receive satisfaction from the seller.
It only lasted a summer and the warranty doesn't cover the shipping costs (very high for something this heavy).
You're better of buying a more expensive battery locally with a usable warranty.
