 Fujifilm NP-45 Battery Has Longest Duration mAh Capacity Than Cheaper Generics |
| Review Date: August 22, 2009 |
| Reviewer: c681, |
I use my Fujifilm Z20 camera a lot for taking videos, and I need many extra spare NP-45 batteries, so I don't run out of power while in video record mode. I already had four Fuji NP-45 batteries. And I decided to try and buy some of the very cheap generics and "to save some money". Here are the mAh duration test results of how long my Fujifilm Z20 camera's camcorder function mode stayed "ON" in Video Record mode before the battery died and self turned off:
=====
I already have, and this is tests of my 4 Fujifilm NP-45 Lithium Ion Batteries. Printed on battery "3.7 V, 740 mAh". About $31.02.
Fujifilm NP-45 Battery #1: 1st test 82:39 minutes:seconds. (Great battery life.)
Fujifilm NP-45 Battery #2: 1st test 82:40 minutes. (Great battery life.)
Fujifilm NP-45 Battery #3: 1st test 79:58 minutes. (Great battery life.)
Fujifilm NP-45 Battery #4: 1st test 82:02 minutes. 2nd test 82:39 (Great battery life.)
=====
I purchased one new Duracell DR9664 Lithium Ion Battery. Printed on battery "630mAh. 3.7V. Compatible Fujifilm NP-45". About $12.10 (but now about $38.58).
1st test 74:32 minutes; 2nd test 72:26. (This battery is okay, but not the best.)
=====
I purchased four new MaximalPower OLY LI-40B/42B Lithium Ion Batteries . Printed on battery "3.7V, 1000mAh, compatible Fujifilm NP-45". About $7.30.
MaximalPower #1: 1st test 56:04 minutes; 2nd test 54:19. (Not good.)
MaximalPower #2: 1st test 57:45 minutes. (Not good.)
MaximalPower #3: 1st test 58:59 minutes. (Not good.)
MaximalPower #4: 1st test 57:35 minutes. (Not good.)
(P.S. the MaximaPower "3 year guarantee" is useless because they require $9.50 for a shipping and processing fee to get a replacement battery. I originally paid $7.30 for this battery.)
(Note: How can this MaximalPower battery claim to have "1000 mAh"? My duration tests show it is not good, or is this hype?)
=====
I purchased one new Dolica DF-NP45 Lithium Ion Battery. Printed on battery "Replaces Fujifilm NP-45. 3.7V 800mAh". About $12.44.
1st test 44:02 minutes; 2nd test 47:23; 3rd test 45:17. (Not good.)
(Note: How can this Dolica battery claim to have "800" mAh? My duration tests show it to be not good, or is this hype?)
=====
I will return the poor not-good batteries, and now I will only buy genuine Fuji NP-45 batteries. (Also, of course, again, I will not believe what is printed on batteries, since any mAh capacity "hours" can be printed (such as 1000 mAh, there is no one to test, confirm, or question the "1000" mAh.)
Note: The Fujifilm NP-45 battery is a standard size battery type, and can be interchanged in your camera with the following batteries: Fujifim NP-45 = Olympus LI-40B = Olympus LI-42B= Olympus 202034 = Pentax D-LI63 = Duracell DR9664 = Energizer ER-D530 = Nikon EN-EL10 = Kodak KLIC-7006.
Note: The Fujifilm NP-45 battery are sold in a open cardboard box, and are not sealed in any way, so you can not tell if you are receiving a brand new battery, or a used one. I recommend buying from Fuji or Amazon or a reputable dealer. I recommend you buy a new battery, and not a "used" battery, since the product paper says it can be recharged 300 times.

| Excellent product. We vacationed outside the country and always a freshly charged battery thanks to this product. It holds a charge for a long time. |

| Battery life is equal to any other I've purchased. Comes with a soft carrying case to protect the battery while it isn't being used. |
Strong battery

| Battery is strong and lasts long. Also charges in less than the 3 hours it says it would take. |
Camera battery

| The only way to insure a charged battery while on vacation is to have a second battery already charged and ready to go. While you continue to take photos, your other batter can be charging. |
