What does it mean on a rechargeable battery for a digital camera when it says "1050mAh" or "800Ah"?

Does the higher number on a rechargeable (Li-ion) battery mean it will last longer that one with a lower number? Please explain, as I want to buy a generic rechargeable battery for my Canon G10 digital camera that's a lot cheaper that the Canon version.
The trouble is that the more expensive Canon battery has "1050Ah" printed on it, while the generic has "800Ah" (or something like that).

Higher ratings means more photos per charge.

Generic batteries come in different ratings. You just happened to find one at a low rating.

Below is a link to another generic replacement fot your Canon NB-7L battery. This one is rated 1500mah (higher than your Canon battery) and at $12 still costs less than the Canon battery. User reviews are very good for this generic.

Higher ratings wont harm your camera they will just give more shots per charge.

Gomadic Excessive Capacity Rechargeable Battery Review

iPhone house owners, particularly anyone without a model new iPhone 4, have battery problems. It is one thing that happens with older telephones, and the iPhone is no exception. With a day's price of battery life and the iPhone rated for only 500 recharges, we're looking for about one and {two} third years. Then once more, the iPhone is on a {two} 12 months contract'and even if we improve sooner, that day-long mobile phone battery isn't all the time a day lengthy beneath heavy use.

What are iPhone owners to do?

There are a number of options: a nokia battery case, which often doubles the scale and weight of your iPhone. Purchase a brand new telephone, which is costly and infrequently especially so due to supplier contracts. Carry {two} telephones (which some already do, although principally enterprise individuals needing a number of carriers). Or just use your cellphone much less and dial down the battery intensive functions.

Gomadic provides a simple answer that gets around all the problems without making your telephone a hulking behemoth. The Excessive Capacity Rechargeable Motorola Battery is strictly because the unimaginative title sounds, a chargeable battery that is a separate device from no matter you're using. In truth, it isn't particular for the iPhone, though the examined mannequin includes a retractable USB cable with the Apple 30-pin connector.

The Gomadic providing is different from the other choices for a few reasons. First, it isn't just double the charge of your iPhone. I used it on and off for the previous 5 months, and it is confirmed to be a lifesaver when my iPhone failed to final even midway by way of the day. (This is earlier than iOS 4.zero released.) This Samsung telephone battery holds around 2-2.5 full iPhone 3GS costs, which is fairly significant. Not only can you go a complete day with no need to recharge your iPhone, you'll be able to go several days with out recharging this battery too.

Second, it isn't particular for the iPhone or Apple devices. The USB port will charge any ready system, together with most of as we speak's USB-centric smartphones. Whereas I have never tested the cost price with totally different phones, they all work with the battery. Just be wary that it solely comes with a spare iPhone connector cable ' if you plan on using a unique cellphone, get one other cable to hold around, or buy the Sony ERICSSON battery with the correct connector. It additionally has a strong constructed-in Led Light, so for those who normally carry a flashlight around (in case of emergency or wild rave social gathering), this battery can change it. After utilizing the flashlight for a big period of time, I discovered that it uses relatively little energy in comparison with actual telephone charging. It'll additionally brighten any dark room, and will easily suffice as an everyday flashlight.

This particular mannequin was truly despatched to me for testing with the iPad, and it is listed as a device capable of recharging the iPad. The Gomadic consultant I spoke with mentioned that whereas it may recharge the iPad, it may possibly achieve this when the iPad is off. My testing found that it'll cost the iPad when on, simply at a slow crawl. In impact, the iPad runs off of the Gomadic battery as a substitute of its own when connected. One check included streaming HD video with minimal battery life left, and over the course of an hour, with half a charge left, the Gomadic battery gave in whereas my iPad fell from 12% to eight% battery life. It didn't charge my iPad, however the iPad wouldn't have lasted 30 minutes without the telephone battery.

Charging the Gomadic HTC battery is a bit of a hassle. A separate connector included plugs into the battery, and the same retractable cable is meant to charge the battery through USB (USB to power adapter). This implies not only will customers have to carry across the separate battery and cable, but a small, straightforward-to-lose connector to cost the battery. Having the retractable cable use connectors is good because users can change between different phone fashions (with extra connectors bought), yet it turns right into a recipe for misplaced baggage. Whether it's looking for it in a bag pocket or losing it within the car, having tiny items for any device is a foul idea. A separate charging cable can be obtainable, but that tacks on yet another cost and cable to hold around.

The Gomadic Excessive Capacity Rechargeable laptop Battery is a effectively constructed and effectively-designed battery, and I exploit it heartily and happily. I hate the tiny connectors, and have resigned myself to leaving it at dwelling and simply charging the battery at night time, alongside my iPhone, though I'd a lot slightly carry it with me for comfort' sake. I do not like to feel compelled to recharge the battery nightly, in the event that my iPhone requires more than a single charge in the day, and for work I always have my laptop computer and/or my automotive round, each of which may recharge any device. At least with this battery, I get to keep my iPhone slim in my pocket, and charged wherever I go.

Questions about Rechargeable Battery

Can you use any rechargeable battery in a camera?

I have a kodak camera and I use kodak rechargeable batteries (the one that is AA that are attached to each other) and I have a Kodak camera dock that charges the battery. I can not find the darn battery anywhere (I need a new one, the one I have will no longer hold its charge) and I am running out of options. Can I get regular recharable AA batteries and will it recharge itself if I put the camera on the dock? Thanks to all!
;0)

Check your camera's manual or a spec page on the internet for the specific battery size your camera uses. If it says AA, you can use at least alkalines. The best are Energizer Lithiums as they last the longest. You can also use any rechargeable AAs out there but make sure they are rated at least 2100 mAh for them to last long enough.

AA rechargeable batteries whats the difference between 2500 mah and 2700 mah?

i have just bought a new digital camera and it uses batteries soo quickly. i am going to buy rechargeable batteries. But i wanted to know the difference between 2500 mah and 2700 mah. i no that 2700 mah is obviously better than 2500 mah, but how much better. how long will 2500 mah and 2700 mah last in a digital camera?
oh and what is the best a charger and batteries?and where do they sell the cheapest?i also want them to charge fast ish?

Right you may get a lot of technical answers on here but I will keep it simple.

The difference between the 2500 & 2700 is so small that you would not notice.

Go for the highest capicty you can afford just make sure they are NMH either should be fine i run 2100 in my camera at the moment and they last for ages

Also a 0ne hour charger is best. you can get faster (15mins) but an hour is the norm for fast chargers

If you are in the UK try the link for Argos. again you will find them cheaper online if you search but thats a good mid range price guide

Good luck
