Digital camera reviews of Sanyo 2,700 mAh AA NiMH Rechargeable Batteries (4-Pack)
Digital camera Review: Excellent results thus far
Summary: 5 Stars
I've only used this set of batteries for a few weeks now. I use it on my fairly high discharge Canon S1. Thus far they have been excellent. It will be interesting to see how they work out in the long run.-agDigital camera Review: Fantastic yet Horrible
Summary: 1 Stars
The first set of these I bought from a different vendor were fantastic. They lasted 2 years in a frequently used camera. I only recharged then because I was going to a cycle meet and knew I would be taking hundreds of shots and I didn't want them to die in the field. They were still working after 2 years use, but I recharged them anyway to be sure.
Then one day my cordless phones needed new batteries. I immediately bought these Sanyo 2700's due their previously proven performance. I don't know if this is a bad batch or what, but these suck. Sometimes my camera won't even turn on after a fresh charge. I have recycled them endlessly in my MH-C204F charger. On last attempt I recycled them 4 consecutive times and put them away in a drawer. One week later they were dead - and that's under no load whatsoever. I think I will try some eneloops next. These are trash.
Digital camera Review: For my application, the BAD outweighs the GOOD
Summary: 2 Stars
First off, this review is based on my experience and not scientific tests. I purchased 8 of these for use with my Nikon SB-900 and SB-600 flashes. When they are fresh out of the charger (La Crosse BC9009) they will recycle the flash extremely fast and last for about 150 shots. However, if I charge them and leave them in my camera bag for a 3 days I'll get about 50 shots. If I charge them and leave them in my bag for a week, they are stone dead. Overall, the batteries that were included with my La Crosse charger (Lacrosse 2600's) out perform the Sanyo 2700 by about 2 fold (again, not scientific). I've been testing a set of 4 Eneloops for about a month and I really like them. The Eneloops give me more overall shots and hold a charge for considerably longer - there is a small hit on the recycle time, but for me the upsides of the Eneloops outweigh this.Digital camera Review: GARBAGE
Summary: 1 Stars
I purchased new Sanyo NiMH 2,700 AA's in Dec 2009. I fully charged then at 270 MA for 12 hours on variable voltage and current power supply as I do with all my rechageable, as per the current rated battery. I ran them in my hand scanner for an hour. Good news. Then next day the same. More good news. The next day, NOTHING! I checked the voltages. At .19 volts is what I read on my DMM. I replaced the batteries with 2,600 MA Tenergy's. I recharged the Sanyo's, then repeated the same sequence again. Same results. I did it again the next days. Dead again. I did another test. I charged them again. I have 2 scanners so I put 2 batteries in each scanner and turned them on to an aircraft frequency. They lasted 2 hours and both went dead within 1 minute of each other. I wouldn't recommend these batteries to anyone. The model number is: HR-3U 1.2 V. I didn't save the reciept as I have NEVER had any problems with any NiMH, or LiPO batteries I have purchased. Stay away from these Sanyo NiMH's. I don't remember the seller and now I'm out the cost and shipping. I'll check on my sales list, maybe I can find the seller there.Digital camera Review: GE/Sanyo Rechargable Batteries
Summary: 5 Stars
These are very good batteries. I charged those in my La Crosse BC-900 Charger. The following were the results after first charge.
The four AAs rated 2700mAh nominal (min 2500mAh) come out ranging 2.8Ah to 3.0Ah. I used the discharge setting of 250mA and charged at 500mA. (Those who use the BC-900 will know what I am talking about).
The four AAAs rated 1000mAh nominal (min 930mAh), all come out above 1000mAh, but very close to 1000mAh. I used the discharge setting of 100mA and charge at 200mA.
