Low current capacity, avoid buying for high power equipments
8 October 2016
I have purchased these batteries for my trimmer and led flash light. These batteries have a capacity of 2.1AH at 1.2v, ie 2.5 Watt hour. A 1 W flash light should run for 2.5 hours with these ideally.
Yes, at the first place everything seems working just ok. I tested running the 1w flash light continuously and it ran way longer than with the kit battery which was 700 mah, but not for 2.5 hrs.
Now coming to the trimmer part, i was using a panasonic trimmer which had an internal battery which was not same as a AA battery, but a modified slightly longer AA battery. I was planning to replace the trimmer battery with this and i sticked a metal cap to elongate the tip and put it in my trimmer. Then only i noticed that the trimmer is running at a lower speed, which indicated that these batteries have a low current capacity. So if you are buying this for a heavy duty equipment like a trimmer, RC car or anything with a motor, i recommend that you go for a costly battery, may be Sony.
As a quick help to someone who is confused whether to go with a higher capacity battery, remember that NiCd/MH batteries require atleast 4 or 5 cycles of full charge/discharge an year for a good life. In case you are buying this for a mouse or keyboard or any low power devices i recommend that you go with a lower capacity one like 1000 mah or lesser so that you can discharge it completely atleast once in 3 months.
And another thing which i would like to mention is not to accept any batteries with mfg date beyond 1.5 years. Because these batteries lose their capacity if kept uncharged for a long time. If you got an old battery from a seller, just return it.
