Rechargeable Lithium Polymer 9V battery 520mAh

iPower is offering the first and only Ultra High Capacity lithium polymer rechargeable battery intended for professional use. Lithium Polymer batteries use a new gel-type electrolyte. This gel has an energy density that is 20% more than typical Lithium Ion batteries and approximately 3 times better than NiCad or NiMh. These batteries are geared toward the location sound person using professional wireless and will out perform any rechargeable battery currently available for this use. Actual Capacity is very close to that of a standard 9V Alkaline Battery (540mAh). The new smaller size fits just about any device and it will actually out perform a standard 9 volt alkaline battery in High Drain Applications.
  • Chargeable in the NEW iPowerUS Charger ONLY.
  • More capacity than any other 9V Rechargeable Batteries available.
  • This 9V rechargeable battery will operate equipment much longer than other rechargeable batteries.
  • Great for wireless microphones, and other equipment that use 9V batteries etc...
  • Can be used as a exact replacement for standard 9 Volt batteries in most equipment
  • Can be recharged hundreds of times, and the Lithium Polymer 9V Rechargeable battery has no memory effect.
  • Special design with Li-Polymer cell, capacity up to 520mAh
  • Lithium-Polymer material, Working voltage 8.4V~6.5V,
  • Standard output current 1~80mA, Hi-rate continue output 500mA/hour, Max. transient current up to 2500mA/sec.
  • Nominal Voltage(V): 8.4V, Discharge Cut-off Voltage: 6.4V
  • Built-in Protection IC to control over-current discharge and under-voltage discharge.
  • iPowerus pv Lithium Polymer Model IP9V520


Frequently Asked Questions:

What is the difference between the consumer 9V-500 and the Pro 9V-520?

The pro 520 contains the best grade/high spec raw materials, with special control electronics, yielding higher capacity and reliability. The 520 is enhanced to power digital systems with switching power supplies. The 520 will be able to handle current spikes,heavy supply filters, shorts and other high current and adverse load conditions, with a lower rate of failure and an average overall product capacity increase of 10%, day in, and day out.

What is the operating voltage for iPower batteries.

iPower LiPo batteries fully charged, will vary from 8.0 to 8.4 volts. Most batteries will charge to 8.2 or 8.3 volts. The batteries will deliver 80% of its power by 7.2 volts.

Lasted one year
December 3, 2013
After one year, very high self-discharge. YMMV, I suppose. For my uses, not worth the cost premium or risk. I\'d rather get mass-produced, industry tested/standard NiMH\'s.

Great batteries
October 29, 2011
Purchased these to use in Shure wireless microphones for my church. We have been using them since the beginning of the year and they are still working great. We do productions for Easter and Christmas and I have never had a battery run dead even for our day-long Saturday Rehearsals. The only problem I\'ve encountered is I need to tighten the negative terminals about once every three or four months so they plug tightly into the mics and the charger.

Still going strong
January 13, 2011
I reviewed these batteries in March 2010. They are stilll going strong. I am using them more now too but they still last me at least 5 days even with the heavier usage. I\'ll give another review next year but I\'m pretty sure it\'ll still be good

Works Great in Wireless Mics
March 27, 2010
Purchased in Dec, 2009, I\'ve used these batteries for 2 theatrical shows now in Shure wireless mics (LX and ULX series). When I did a first test, I let a mic run nonstop (I set it up near our boom box while we were working on the set). It did a full 8 hours and was still going. For two-show days we do recharge between shows (15 minute recharge), and we\'ve noticed the battery indicators on the newer Shure mics read even newly charged batteries as \"1 or 2 bars\" of power, but they work the whole show, no problem. Definitely a good investment. In two shows I\'ve already recovered what I would have spent in regular batteries.

long lasting
March 19, 2010
I\'ve been using these batteries since 12/09 and have been very satisfied. I use them in medical equipment called an Abbott I-Stat. It uses 2 batteries at a time to power it. When fully charged the batteries last at least 5 days usually 7 to 9. By the way my machine stops working when voltage drops below 7.25 volts. These batties also seem to recharge themselves to an extent when they arent being used cause they voltage gauge changes and goes up after they sit awhile bewteen uses. I would definitely recommened these to others. Dont know about how 1 to 2 life of them but I will let you know.
