Well I have came across many threads about Internal and external battery for Sensation and I know it's best to have an anker 1900mA or a Li-ion external battery.
However, I used 4 AA 2500 Ni-MH battery which can be found on Amazon: Eneloop XX 2500mA
I used a little device that can hold 4 AA battery and has a usb port which convert the voltage to ~5V and max current of 1A.
I wonder if it will damage my internal battery (currently HTC OEM) and will it give a good transfer of enegy between those battery compare with external li ion and internal li ion.
I know this is a complicated way to solve battery problem but I used to be iphone user so I cant change internal battery (which is crap), so suggestion of buying a new battery is appreciated but it will be more welcome if you can provide information that Im seeking.
Thanks for your time

I'm trying to build an external battery for my ppc using some (conventional) rechargeable batteries (AA type)....
I want build it using a micro USB cable connected to the batteries.....
I know that the usb voltage is 5 V...
Each rechargeable battery is 1.2 V.
So I need at least 4 batteries, reaching 4,8 V....
Now I have a 0,2 V gap....
Is it important or not?
I have to use a diode and/or add an other battery?
Let me know.......
Thank you!!
why not just buy one?

Thank you for your answer...
That is a usefull thing for me..
But I want build it by myself......
I really think the 0.2v depends on if you are planning on running your PPC on the ext battery or just "topping up" the int battery. If you intend the ext battery to be the sole supply of power then you need to match the Voltage and current pretty closely. If you intend to top up your internal battery then it isnt so imprtant as you are providing a trickle charge facility.

I want charge my internal battery using this external tool.....
As if I'm charging my Touch using the usb connector...
So the external battery wouldn't be the sole supply of power...
So is not important the 0,2 V gap while it's charging?

I would like to find out how long would this pack last with eneloop battery's.
anyone have any idea?
also if it would be possible to build or find a external battery that can take 8AA battery's.
Eneloop AAs are rated 2,000 mAh?
my rough guesstimate, you'll get about 4x your normal stock battery life from the pack, after you factor in losses from heat and from converting the pack's juice into your cell battery.
maybe a little more?
whats the total mah for the pack if i put in 2000mah batteries? 10 000mAh?
RAVPower rp-pb03 external battery
I own one before, it is really charge my HTC EVO 4G with bad result. I only use the device once before it basically melted. For reference, I used Sanyo Eneloop batteries in the charger and I used the retractable cable provided with the mini usb adapter. The charger did recharge my batteries, but it got so hot when charging my phone that the outer case warped from overheating. So I ask to replacement, however, the second one I received got the same problem. Also the charging speed is very slow.
I bought another RAVPower rp-pb03 external battery on Amazon one month ago. Since now the battery works very great. I love this device! Not only does it have a very handy flashlight, but it never leaves you guessing how much power is left. It works with my phone, my wife's phone and both of our tablets (all different brands!) The size is nice and compact, and I like the robust weight. It's easy to use, and compatible with everything I've tried! This is by far the BEST accessory I've bought for my electronics by far!
Has anyone tried any of the external battery solutions available out there? I've read that the Kensington one is good, but it's only like 1200-1400 mAh !
I've run across a few on Ebay that are running 4000-5000 mAh - great for multiple charges!
Anyone have any feedback on any of these?
I have used a few different ones over time. I currently have an Energizer pack with a 4000mAh capacity.
I recently saw a a 40,000mAh pack at Radio Shack for around $120. I almost bought it, just on general principles.
Anyway, yes, the portable packs do work well. But remember that the mAh capacity of the pack doesn't translate 1:1 to charging capacity. The battery in the pack is only a single 3.7v LiPo cell, and the battery in your phone is ALSO a single 3.7v LiPo cell. These packs use a switching regulator to boost the output voltage, which means that the cell will be discharged faster than you might think. If you want to fully charge the battery in the Triumph, you should try to find something with at least 2000mAh capacity.
One of the more interesting solutions I've seen at the Sprint store was an integrated charger. It had a USB jack, a short micro-USB cable, and an AC adapter all built-in. So you could basically use the thing as a USB wall charger, then unplug it and take it with you when you expect to need a little extra juice on the road.
Personally, I'd like to see more portable Lithium-based packs that can also put out 12v for larger devices. Ideally, I'd love to be able to power my phone and a portable speaker system all from a single battery pack. Perhaps someone will get smart and build a box to house and adapt the 2-cell rechargeable packs used by RC car enthusiasts...
I purchased a 1500mah Anker battery off Amazon for $15. Works great!! Much better than 1380mah stock battery
Sent from my Rooted MOTWX435KT using XDA App
this one?
http://www.amazon.com/Anker-1500mAh...2?s=electronics&ie=UTF8&qid=1316908026&sr=1-2
anker do make external battery, i have one this ,5600mAh, very handy!
seems like have a 10$ off now, it's 39.99$! damn, i purchase with full price 49.99
hello.
is it correct that the anker extended battery for the s4, should be showing a capcity of 2600mah in battery monitor pro?
is it because it is 2 x 2600 batteries joined together?
bit confused.
To my knowledge battery Mon pro won't be able to automatically determine accurate capacity of the battery when you just plug it in. It has to calculate it through extended use by monitoring discharge rate, and even that is not accurate.
anker 5200
same as me,
i try using battery doctor or du battry saver but it's only show 2600 mah in system.
i wonder how to make it show 5200mah
just watch the voltage. You will know what it's got left by watching the voltage drop after a few days. The cheap apps are telling you 2600 because that's what the phone comes with. It's written in
Use Android Tuner or battery calibration on appstore, they give actual voltage
Any Doubble Power Battery ???
Six hours continuous use
Confirming my Anker 5200mAh Extended Battery provides six hours continuous use with my Galaxy S4.
Very happy with my purchase, and recommend the Hyperion HoneyComb TPU Extended Battery case for use with this extended battery.
how much do you know about external chargers

many external chargers especially ordinary chargers are oversized in capacity. though they may be very cheaper, they are usually shoddy and deceptive. i recommend you to read this article.
Don’t buy external battery before you read this!
As we have more and more gadgets, we are expecting our gadgets can always work when we need them. Our gadgets can do almost everything — until they run out of fuel. Times when you need to make that important call, send out an urgent e-mail, or need to use the apps on your device – but alas there is no battery…we’ve all been there and know first-hand the stress of being offline when you need to get things done!
External battery is indispensable for our smart life, but how much do you know about the external battery? Does your external battery really charge your gadget or make the damages to your battery of gadgets?
1) What’s external battery?
External battery serves as an ‘extra battery’ or external charger for your phone or other electronic devices.
2) Where is external battery made from?
Majority of the external batteries in the market are actually made in China. And the battery cells or PCB modules are from different countries.
3) How do I charge the external battery?
You can charge your external battery via the charger that came with your phone, computer usb port or using other external battery
4) How long do I need to charge the external battery?
It depends on the REAL CAPACITY of the external battery. The larger REAL CAPACITY, the longer charging time may required. Different charging methods may result in different charging time as well. Charging with the original charger will be faster than charging with computer usb port.
5) Why sometime I need longer time to charge the same external battery?
Even though using the same charging method, the charging time may be differ due to environment, temperature, power flow and etc.
6) What is mAh?
mAh mean milli Ampere Hour, the capacity of the external battery is measured with mAh
7) Is a 12000mAh REAL CAPACITY external battery, able to charge a 1500mAh capacity phone for 8 times full?
This is a common mistake made by most of people. For rough calculation of the total charge time, kindly use this formula
REAL CAPACITY * conversion rate * phone battery health / phone capacity = total charge times
EXAMPLE: 12000 x 0.8 x 0.8 / 1500 = 5.12 charge times (0.5-1 times plus minus)
8) What’s conversion rate?
Conversation rate is the remaining percentage of the battery after the battery loses in heat or PCB operation.
9) What’s phone battery health?
In simple, it means how ‘healthy’ your phone battery is. Phone battery storage capacity will be lower and lower. That’s also the reason why our phone can last longer when it’s newly bought than after 3-6 months of use. Different mobile phone models also will affect the calculation as some phones drain battery faster than others.
10) What’s PCB?
PCB means Printed Circuit Board, which controls all the operation flow inside the external battery. A good quality PCB will allow the external battery to charge more and have better durability
11) What’s the difference between 18650 and Li-Polymer in the external battery?
- 18650 size and dimension are fixed. Li-Polymer size and dimension are flexible.
- 18650 produces more heat. Li-Polymer is much safer
- 18650 is cheaper. Li-Polymer is more expensive
- 18650 has a higher self discharge rate. Li-Polymer has a very low self discharge rate
- 18650 battery capacity drops faster. Li-Polymer battery capacity is more durable
12) What’s the common REAL CAPACITY in 18650 external battery in the market?
- External battery using 1pcs 18650 is 1200mAh – 2600mAh
- External battery using 2pcs 18650 is 2500mAh – 4400mAh
- External battery using 3pcs 18650 is 3750mAh – 6600mAh
- External battery using 4pcs 18650 is 5200mAh – 8800mAh
- External battery using 5pcs 18650 is 6500mAh –11000mAh
- External battery using 6pcs 18650 is 7800mAh –13200mAh
- External battery using 7pcs 18650 (no info)
- External battery using 8pcs 18650 is 10400mAh –14400mAh
1 3) Is there any external battery with a capacity higher than 2200mAh per 18650?
Yes. There are, but it’s not common due to the expensive pricing.
14) What’s the difference between branded external battery and generic external battery?
Branded external battery is mostly sold in REAL CAPACITY. Generic external battery is mostly sold in MARKING CAPACITY. That’s the reason why you will never see any branded external battery (standard size) with a capacity as high as 30000mAh – 50000mAh. That’s also the reason why a good 12000-13000mAh external battery is able to charge more or almost the same as the market level of 30000-50000mAh. Most of the external batteries sold on amazon.com with low price are MARKING CAPACITY but not REAL CAPACITY. Those with higher price and long warranty(more than one year, some brands offer 18 months of warranty, like Sony, KINKOO, Xstorm) are REAL CAPACITY and reliable.
15) Is it true branded external battery won’t explode and generic external battery will explode?
Anything to do with battery will have a chance to explode. No matter it’s branded external battery or generic external battery. But chances for both branded and generic external battery to explode are very low, except for those cheap and poor-quality 18650 batteries. And the Li-Polymer is safer than 18650 battery, it’s easy to fit the high-temperature environment.

I need to replace my current external battery with a faster charging option. Link below. During the day, my phone actually loses its battery while charging from the external battery and the phone gets quite hot. What should we get? Our phones are not capable Qualcom quickcharge 3.0. Has anyone bought an external battery?
This link is very similar.
