APC External Battery for Extended Runtime for Back-UPS Pro Model BR1500G

I don’t know which category this review will be labeled as, but this is a long term review of the “BR1500G + BR24BPG” combo. I just replaced all the original batteries (in both units) after a significant power “event” (lost one phase of my power) revealed a major loss of runtime; they lasted 4 years, 10 months. Before replacement I was able to determine that the original RBC124 in the BR1500G had failed, but that wasn’t revealed until I disconnected the BR24BPG and did a battery test on just the 1500G. I also tested the OG batteries from the 24BPG after they were removed. All tested good (but still glad I replaced them.) Once I replaced the bad RBC124, the UPS said the new one was bad! That status was OLD, for the bad battery just removed. The new battery must test OK to reset the status. It probably won’t test OK immediately. Give it an hour or so to settle in, then it will test OK and clear the bad battery warning. If it keeps testing bad, then worry! I’ve been through this a couple of times now on 2 similar units. The old adage “time heals all wounds” seems to apply in this case! If you decide to replace the batteries in the BR24BPG yourself, they are RBC17’s (12v, 9Ah); there are four of them. Not hard to do, but some experience recommended. There are cheaper “equivalent” replacement options available, but keep in mind that this is a bit of a project. For me, the fewer times I have to go through it the better! Getting into the BR24BPG case is a little tricky. There are videos available, but a couple of additional useful notes will help. Pry the front cover off from the bottom (there’s a square hole), a straight blade screwdriver will work. It will seem like you’re going to break it. That feeling won’t be alleviated until you get it completely off and find that nothing broke! Still, work carefully, using just enough force to get the job done. Next, the trick to “opening” the case (after removing all the screws, and back cover) is to SLIDE the “top” side back from the front, then lift it up and off. The “top” side is the one that’s “up” when you remove the 3 front screws. There will be resistance when trying to slide it, but keep working it until it finally does. Same precautions as before, but no screwdriver required. Overall, this is a great combo. It supplies tons of runtime with a fairly small footprint. My internet gateway and separate Wi-Fi (OG Orbi) run for 5-6 hours on battery. If my computer is on, that drops to about 3 hours. Impressive!

Good deal. This is the external add on battery pack for APC 1500VA Back-UPS pro, BR1500G. I bought the UPS too. they look beautiful together and supply me with 277 minutes run time at 75 watts. That info comes off the front panel. I am not using powerchute software on this ups, because there is no pc attached to this ups. I have used powerchute on my other ups's, the software works good. The APC BR1500G UPS is the only affordable UPS I could find with optional external battery pack. Get the 1500 watt Back UPS PRO, has to be the pro one.

I purchased the external battery pack along with the Back UPS Pro 1500 unit for my work station and two large monitors which consume about 500 watts of power. I owned the predecessor Back UPS XS 1500 unit and external battery pack, so thought I would stick with APC since the other units lasted almost five years before the charger gave out. When I first installed the new unit, I anticipated hearing some fan noise for a day based on other reviews. However, the fan ran for three days straight, whether or not the equipment was running and it was much louder than I expected. I contacted APC and they told me the fan would run at all times, forever, whether or not anything was turned on. Fortunately, it turns out they were wrong. Last night, the fan finally turned off and has stayed off. Same thing today when I started my work station, dead quiet UPS. Bottom line, once you get past the initial charging period, the unit runs quietly. Note that if you only purchase the base unit, it contains two batteries, so it might run the fan for one day, but since the piggyback unit has four batteries, it takes an extra couple of days to charge.

This (along with the external battery) are great for keeping low wattage items running during power outages. They can't handle higher power items like microwaves, refrigerators, hairdryers, heaters, etc. but they are excellent for running several sets of LED string lights, and keeping a laptop and satellite system powered up so you can check weather online, make WiFi calls, recharge phones. etc. If you combine these with some of the solar system generators like ECOFLOW, then you have the ability to both run the higher power items from those "generators" and also to recharge the APC systems indefinitely. Combine all of this with a few LED floor lamps, small vehicle refrigerator, and a portable electric water heating kettle, and you will be well on your way to carrying on unfazed if the power goes out. As for the APC products specifically, they are very low maintenance, and changing the batteries in them is very easy. Additionally, their support team is great. I had a smaller APC get damaged by (I think lightening) and they sent me a new replacement with no hassle at all because it was still under warranty. Finally, one other thing that I like about the APC units is that they are modular...meaning that you don't have to buy a set of these all at once. You can buy the main unit and add the extra external battery later. So, this makes it easier to start with something that works, and add to it later as the budget allows. I literally recommend these to my friends and family.

I purchased this external battery for my BR1500G UPS. Everything works fine but when i plug the external battery pack into the UPS the fan starts running. I concluded for some reason the external battery pack arrived in a state of discharge (this may be normal) and will require around 24 hours to fully charge. At which time the fan should (hopefully) turn itself off. Pro: The external battery pack more than triples my run time to about 96 minutes.. I'm using it to power a 75 inch TV and satellite receiver that draws around 240 watts. Con: The external battery pack is difficult to open when batteries need replacing. The reason for 4 stars.

I've used an APC battery back-up for eight years. During some recent power outages, it was necessary to remain operational for a longer time. This battery back was easy to add and has more than tripled available run-time. Check your APC battery back-up to ensure it is capable of this addition.

This battery pack contains four 12v 9ah batteries. The batteries are model CSB HR 1234W F2. This battery pack is not made so that the batteries can be easily replaced by the user like the main UPS unit that it connects too. This is disappointing. They could have designed it so that the batteries slid out for easy replacement like they do on the master UPS unit. But you can still easily replace the batteries with a little work. Although you might break off a small plastic tab or two on the front cover in the process but it won't matter or hurt anything. Presumably your two year warranty has expired before you need to replace the batteries so you will have nothing to lose. 1. Remove the 6 screws on the back of the unit. 2. Pry off the front cover. 3. Lay unit on it's side so that the 3 screws on the front are facing up. 4. Remove the 3 screws on the front of the unit. 5. Slide the cover towards the back of the unit to remove it. 6. Disconnect the leads plugged into the F2 terminals on the batteries. 7. Remove batteries. 8. Insert new batteries and reconnect the leads. When I plugged the unit into my BR1500G UPS it basically tripled my estimated runtime per the PowerChute software. Which is exactly as expected since the BR1500G contains two batteries and the external battery pack contain four additional batteries. My reported runtime is now 96 minutes with 233 watts draw. I found no fan inside this external battery. The BR1500G contained 2 Kung Long WP1236W batteries. 12V 9ah 36W. Made in Vietnam. This external battery pack contained 4 CSB HR 1234W F2 batteries 12V 9ah 34W. Still rating it 5 stars. Although I'm disappointed about difficulty to replace batteries when the time comes. Also, I'm really curious to know if the BR1500G is able to inform the user when the external battery needs replacement or if it just gives a general replace battery message for all batteries. Looking forward to seeing future reviews.

If you're working from home and can't afford to be taken offline without notice then you have to buy this. It's an add on to the main battery, but worth every penny. I had previously rigged up a huge battery back from HF to add on to the system. After COVID hit and the frankenbattery went out on me I decided to spring for the real deal. It looks professional and does the job. We have two powering critical electronics in the house and have not been taken by surprise by the handful of power outages over the last year while working 100% from home.

UPS fonctionnel pour backup alimentation et protection surtension pour systemes informatiques,TV SAT, chaudiere, ....

Ha praticamente triplicato la durata di mantenimento dell'energia in caso di assenza di corrente del mio BR1500GI, quindi è decisamente efficace. Probabilmente verserò lacrime amare il giorno in cui dovrò sostituire 5 batterie anzichè 2 :)

Passt bestens und ist leicht zu installieren

Took a while to get delivered but now installed, we can work for over two hours before the power runs down. We have an additional backup battery pack to give us longer running time and its worth it.

Bought these for work. They seemed to do a good job backing things up.
