The battery is too big, but works.

Your site suggested the wrong battery for my battery backup, but the battery does work it just does not fit in the enclosure... I should have double checked numbers and such of the actual battery, but that is why I can look them up by what backup I have on your site...

The new replacement battery won't charge

Verified Purchase:Yes
I purchased this for an old APC model BK650MC. I made sure the battery was securely connected inside, tried to charge it without unit on. When I turn the unit on, it just beeps as if the battery is dead.
No, I would not recommend this to a friend.

When new, it would not hold a charge even with nothing connected to it and the unit turned off.
Cons: Part Failure

This was the tenth replacement in my old APC Smart UPS 620 (but only the second one from APC) since 2000. Historically, I've gone from one to three years of life before failure, but I'm starting to believe the off-brand, over the counter replacements are the reason for the short life spans.
Pros: Easy to Perform Maintenance, Ease of Management, Good Value, High Quality, Fast, Good Vendor Support, High Confidence Level in 24/7 Uptime
I would recommend this to a friend!

The basic ups device has years of life yet. Being able to replace the failed battery easily and affordably is the perfect solution to battery aging. I've replaced UPS batteries before and expect to do it again as needed.
Pros: Energy Efficient, Good Value
I would recommend this to a friend!
