## Description

desertcart.com: Mighty Max Battery 12V 9AH SLA Battery Replacement for SEL HYS1290 Brand Product : Health & Household

Review: Just what I wanted - This battery is exactly what I have been looking for. It's 12 VDC, 9 Ah, SLA, and it has M5/#10 posts. My 1500 VA APC BACK-UPS batteries went bad after about four years, so I decided to get these instead of an overpriced battery pack. Of course, these won't fit inside perfectly like what was intended to be used with it, so I put them under my desk. I connected it to my UPS with 8 AWG wires, and I used M5 hole to spade terminal adapters since the UPS itself uses female spades to connect the batteries. The originals were 9 Ah, so I got the same in order to keep the time remaining accurate and ensure that it would all work as expected. I no longer am getting error codes or random instantaneous battery levels dropping to zero then going back up (and the UPS not being able to work off of battery power), so I'm happy. I also checked the UL file for the batteries, and it's legit. Get this battery if you want a great price on a lower capacity SLA battery that doesn't force you to use spade terminals.
Review: Nut and Bolt terminals on sealed Lead-Acid Battery - My car jump starter uses a sealed lead-Acid battery that had gone dead after many years of use. Rather that throw it away and buy new I decided to refurbish it. This battery was a perfect fit match and most importantly it had the correct Nut & Bolt terminals that are necessary for this device. The battery arrived, safely packaged in protective foam and cardboard box and with terminal protectors to prevent accidental shorting of the terminals. The battery was charged. After installing it it only took a short while to charge up to full level in my device. It was relatively easy to replace it and will give this battery pack a few more years of life. Photo is of the new battery installed in the battery jumper device.

## Questions & Answers

**Q: Terminals - Are they oreinted as shown in the picture?**
A: yes

**Q: return policy?**
A: I dont mind

**Q: Where do I plugg the battery changer?**
A: Please keep in mind that this is only a battery. It’s like the battery in your car (only slot smaller)  The terminals are the connections to connect to the device you are starting, for instance. 
  You can connect a charger, with plus & minus “alligator” type clips from a charger. If you are using the battery for a “Hot-Shot” jump start device, the Hot-Shot has a port/connection to plug in its proprietary charger.
