istvan_sandor Posted October 5, 2007 Share Posted October 5, 2007 Hi,I have just ordered a pair of no-name BP-511 batteries for my 40d through thefamous auction site. I have already been using no-name batteries for cca. 3 years and they cost me1/4 of the genuine Canon batteries, store 25% more juice and lasted (so far)twice as long.The ones I have just ordered (not from the same source as the current ones) cost5 USD each and they are 1800mAh so, dirt cheap.I never thought about any potential damage caused by batteries (so, I may havejust been lucky with the current ones) but this made me thinking just now.Could someone tell me whether I should be cautious and avoid "no-name batteries"or I should not worry. Also, is there a way to check batteries prior using them ?(I have a Volt/Amper meter if that can be a tool to check them...)Thanks a lot and sorry for my English...

davebell Posted October 5, 2007 Share Posted October 5, 2007 I've never experienced any problems with no-name-brand BP-511s. They're damn good value, at least the brandless name I use, compared to the rip-off originals! Link to comment Share on other sites More sharing options...
colinsouthern Posted October 5, 2007 Share Posted October 5, 2007 You'll be just fine - stop worrying :) Only observation I've made is that it's best to avoid cells that are made in China - Japanise ones are far better. A good source is www.stirlingtek.com Cheers, Colin Link to comment Share on other sites More sharing options...
grant g Posted October 5, 2007 Share Posted October 5, 2007 it's www.sterlingtek.com About half (perhaps 12) of my BP-511 style batteries are third party and they often perform better and last longer than the Canon ones. Link to comment Share on other sites More sharing options...
big kahuna1 Posted October 5, 2007 Share Posted October 5, 2007 AVOID AT ALL COSTS the "Digital Solutions" brand. They are worthless, and for 1/3 the price of Digital Solutions brand you can get the NO Name Japan cells That work great. Link to comment Share on other sites More sharing options...
PuppyDigs Posted October 5, 2007 Share Posted October 5, 2007 I've had excellent results with sterlingcrack 511s. Better than the Canons that shipped with my bodies. I've seen pictures of generic 511 sold off ebay that when up in smoke... Sometimes the light’s all shining on me. Other times I can barely see. - Robert Hunter Link to comment Share on other sites More sharing options...
jimstrutz Posted October 5, 2007 Share Posted October 5, 2007 I just had another Canon brand BPi511 give up the ghost. They seem to work for 2 years (sometimes nearly 3 years) and then fail to hold a decent charge. I always date stamp my batteries to see how old they are getting. When they start fading early I toss them and order two more. You always want to buy two because some are defective right out of the box, and they are not worth returning. The cheap ones I've gotten in Hong Kong via ebay seem to go, and go, and go... Puppy Face points out a problem with generic lithium batteries though. There is supposed to be a thermal fuse that kills the battery (permanently) if it gets too hot, but some some of them seem to have gotten out of China without the fuse. If lithiums get too hot they can short out and then explode, or at least catch fire. I've never had that problem though, and continue to tempt fate.

john_sarsgard1 Posted October 5, 2007 Share Posted October 5, 2007 One more vote for Sterlingtek. Work great, cheap, umbelievably fast service. Just as good as good service gets. Link to comment Share on other sites More sharing options...
zackojones Posted October 5, 2007 Share Posted October 5, 2007 I bought some DigiPower batteries at Best Buy when I picked up my 40D and they have been great so far. My only complaint about them is they don't include a cover like the Canon batteries have. Link to comment Share on other sites More sharing options...
santa1 Posted October 6, 2007 Share Posted October 6, 2007 thanks for the reference to sterlingtek. I'd used them before but forgot about them. I needed 6 more 511's for my 40D so that was just the ticket. much appreciated. Link to comment Share on other sites More sharing options...
carnagex_carnagex Posted October 6, 2007 Share Posted October 6, 2007 Sterlingtek is what I use in my 10D and 5D, both with no problems. (they last so much longer then the Canon ones, and a lot cheaper). Link to comment Share on other sites More sharing options...
