These units were about seven years old, so the original RBC17 batteries were well past their expected lifetime. In my application, these aftermarket replacement batteries work well, although I discovered a problem with the UPS units which prevented their batteries from being charged. The ES750 UPS's both had a defective electrolytic capacitor (330 uF, 25V rating) which disrupted the charge circuit. You can measure the charging current by inserting an ammeter in series with one of the battery leads. Initial charging current (on a discharged battery) should be about 0.4 A on a working ES750. The capacitors exhibited a slight bulge at the top of the can where the vent is located, indicating electrolyte leakage, a fairly common problem with electronics. When removed from the pc board, they both measured very low on a capacitance meter. They were not shorted, just low on capacitance. Replacing the capacitors and batteries restored proper operation. Both UPS's work fine now. Hopefully they're good for another five years or so. I suspect the run time might be slightly less with the replacement 7 AH battery, but I'm willing to accept this compromise to save $ on the purchase price of the battery. One note of caution: I don't recommend repairing a UPS unless you have experience in this area. If you do, observe proper polarity when replacing the electrolytic capacitor. ### ⭐⭐⭐ 3.0 out of 5 stars Ok since was much less than OEM battery *by W***D on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 14, 2018* While had already upgraded to better UPS, bought this battery to extend life of predecessor. The predecessor is an APC Back UPS 650 ES. While arrived on schedule, battery was only in a padded envelope. Fortunately it is sturdy, but the amazon pic of the terminals is worth noting. They are narrower than my APC used and was concerned over potential to fall off. I contacted seller and they sent adapters. The adapter are an improvement but was extra work to get them seated well. Not sure why the battery had wrong size terminals originally.Would have preferred to get battery with the correct size terminals. At the very least, it cannot be very expensive to ship adapters with the battery. Concerns me whether other compromises may have been made. Time will tell. ### ⭐ 1.0 out of 5 stars Not so good *by J***. on Reviewed in the United States πŸ‡ΊπŸ‡Έ on April 25, 2015* Installed 4-16-2015 - It fits perfectly and is a great price but my APC performance monitor says only 6 minutes of estimated battery back up time. It has worked through a couple of power flickers now but haven't had a power outage yet to see how long it will actually last. It's only been installed a little over a week now but no problems so far.Update 5-14-2015 - APC performance monitor now says less than one minute back up power time. Had some storms yesterday (but no power outages) and computer shut down twice....battery did not provide any back up power. I do not recommend this battery....spend the extra money and get the original APC.Update 5-17-2015 - For the record, the seller, Ace Comp Solutions has agreed to replace this battery. I give them a thumbs up and a "great seller" recommendation. Hopefully the next one will work better. I will update this to give performance review of the next battery after I receive it.Update 5-29-2015 - I received my replacement battery a week ago. One day after installing it my APC performance monitor shows 6 minutes of back up power available. After one week it is now saying 2 minutes of back up power. My one star rating still stands. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/6529563-excessups-apc-smart-ups-back-ups-rbc-17-rbc17-replacement](https://www.desertcart.kr/products/6529563-excessups-apc-smart-ups-back-ups-rbc-17-rbc17-replacement) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-23*
