I purchased this for my Honda MRX217 mower, rather than the $90 Honda battery. I note that it is less capacity. I have, in the far past, visited Power-Sonic's factory in San Diego, and was highly impressed with their battery construction. This has worked well on my rough ground. and recharges properly from the mower. Higher capacity batteries, such as the Honda, most likely have thinner insulators, and more susceptibility to vibration. (Note, I have NOT tried the Honda Battery, so this speculation could be incorrect.)So far, then, I'm quite happy with this purchase.
