Genuine HB4F1 Compatible Rechargeable 3.7V 1500mAh Li-ion Battery for Huawei E585/E5830

Pros: It's a battery. Useful for providing extra lifetime for your phone/mifi. I used it for a huawei E585 I could do a DIY modification by removing the lithium battery connected to it and solder on 2x 18650s, providing my E585 with a much much longer battery life (looking at 20hrs or so), so this is useful for people who aren't so concerned about aesthetics.

Cons: Tested at 0.3A discharge from a start voltage of 4.09 resting voltage. Cut-off voltage of 3.00V. I know this is not the normal standard of testing batteries but I don't have the time to conduct a test at 0.1A discharge rate. Capacity is 635mAh from the above test conditions. That's highly overrated

Other: Buy it if you need to, just be aware that it's about 2x overrated. Good for DIY

Pros: This battery is WAY cheaper than the original battery, still it holds a pretty good charge.
Its a very good fit in the cell phone and dimensions are almost spot on compared to the original battery.
Ordered 3 batteries and they all hold the same charge.

Cons: The batteries are not genuine as stated in the description, they are both visually different and share the same serial number (bought three of them)
Mine came slightly larger than the original battery, but no problems making them fit.
Visually the silver lines on the back of the battery is not identical to the original.

Other: Even if these are not genuine its a very good deal, price is extremely good, it holds almost the same charge as a new original battery and they fit just fine.
Bought these for having spare batteries when on holiday or for longer trips and for that they are just perfect.

Pros: The battery fits easily inside my Huawei Ideos X5. It works just as advertised. Just plug it in, charge and you are good to go.

Cons: Doesn't work as long as the original battery, but it's pretty good as a backup battery. The battery is not genuine, but very good quality.

Other: I definitely recommend this as backup battery. Just get a external charger to go with it and you are good to go. :) Very good value for its price!

Pros: Cheap and works exactly as the original battery. I do 8-12 hours with the batteries once charged fully, just like the original does.

Cons: Is slightly bigger in size, need a tool to whip battery out of the phone. You can scratch off a bit of plastic from the top/bottom sides to make it fit better.

Other: Perfect deal to have reserve batteries on holidays or a long weekend. The batteries are small enough to fit in a man's wallet.

Pros: Ordered 3 batteries and they are working great as backup battery for my Huawei e560 pocket wifi : ) The quality of the battery is good. They holds great charge and pretty looks the same with my huawei e560 battery. Very cheap compare to other products I found on other online store out there. Delivery is fast.

Cons: For the cons, I think none so far : )

Other: Very nice backup battery for Huawei e560 or other gadgets that uses same battery model.

Pros: *Really cheap *Fits perfectly in Huawei Ideos X5/U8800 *Works very well (at least better than my 18 months old original one...)

Cons: *Ordered two of these. One is working ok while second one didn't last even one day (from 100% to 4% in 10 hours). That's why only 3 stars to quality. *No matter how many mAh there is, it is always too little :)

Other: Yes, go for it if you need a new battery. And with this price it's ok to buy two!

Pros: As hard original wing, and work on my huawei E5836 3G wifi router.lasts about 2 ½ hours to the router or masxima speed HSPA.

Cons: I heat my router when the paper was crumpled battery, while the original does not happen that. For the rest does what it should do.not think it is as lithium polymer says.

Other: not original, but it works like the original.no date of when it was made ??and whether the original.

Pros: Ordered 1 battery and it is working great as backup battery for my phone The quality of the battery is very well. They holds great charge and pretty looks the same with my phone. Very cheap compare to other products. Fast Delivery.

Cons: Both visually different and share the same serial number. Visually the silver lines on the back of the battery is not identical to the original.

Other: Very good backup battery for my phone. Price is extremely good

Pros: Good capacity. almost as good as original huawei battery but for 5x lower price. The quality of the battery is very well. For that price it's great idea to take one more as backup witch You can have in wallet.

Cons: Is slightly bigger in size than oryginal one, need a tool to take out battery from the phone.

Other: for that price the quality and lifetime is excellent. I recommend it as replacement with great parameters.

Pros: I bought two of these batteries to try to "resuscitate" my generic tablet (similar to SKU: 107317) and worked pretty well!! It's not only bring back the device to life as it actually boosted the working time of the device.

Cons: Nothing that I can think of.

Other: As a replacement battery for a completely generic device, it worked like it was designed for that end. If you have a generic tablet with dead batteries and knows how to use a soldering tool, I strongly recommend these batteries.
