This was a no brainer to replace. APC tells it correctly and made my experience with this backup a real enjoyable experience. Recommend for anyone to use their products.
I bought replacement batteries for two UPS that were no longer holding a charge. With the new batteries they are now as good as new for a whole lot less than buying new ones.
This purchase did not solve my problem (the unit alarm is sounding) and I can't help but wonder if it's because of a procedural shortcoming because there was no installation guide as advertised. Is there a procedure to charge the battery? Is there a procedure to reset the alarm? I may never know...
APC did an excellent job at shipping my battery the next day. the shipping costs were very reasonable and they even accepted an online discount coupon. Great job APC!
