Batteries are not lasting very long - Cameras

Since it's brand new, return it. You didn't say what type of tablet it is, but they should last for many hours on a charge.

Other timers have a back up battery that lasts a few hours or days.
Other timer have super capacitor backup that lasts week or more.
Some timers are powered by the battery, and battery lasts 1-3 years.
The product manual should have some information.

The scooter uses batteries specifically designed for deep discharge applications. If your new batteries are not lasting then they may only be suitable for standby or backup type applications like for your house alarm system or garage door opener when the mains power goes out.

You must take a lot of flash shots. Try using Energizer Ultimate Lithium Batteries. They cost more but they last up to eight times longer. They're 1/3 lighter and they don't discharge while they're just sitting there like other batteries do.

A good way to shop for a longer lasting battery is to pay attention to how high the mah value is. The voltage is how much power the battery actually puts out at once, but the mah determines how much storage the cells have. So if you see one battery that's 1300mah and another that's 2200mah, the 2200 will most certainly stay live for longer.

Yeah It Sounds like the battery is just had its last charge they only last for about 300 charges a piece i would get a new one go for at least a six cell they will last longer...Let me know if this works for you.

You need to replace the battery . There are many software available in website for checking the utility of the battery .
How old is your current battery ?

This depends on how much energy and power the hearing aid needs, how often you use it and what type of hearing aid it is. Some batteries may last days while others can last weeks. Consult your hearing professional and read through information supplied by your battery manufacturer to ensure that you follow the steps to maximize the life of the batteries.

Batteries last about a year depending on if you let it fully discharge before recharge the very 1st time you use it.
the real average is to expect about 6 months usage before it degrades. by one year you'll be lucky if it gives you 30min charge.

Hi,
For acer 9410 you have 2 options for battery. an 8 cell battery which normally would last for 3.5 hrs. or a 6 cell battery that lasts for 2 hours. but that would depend on the application that you are using. for example, the battery will last longer if .you are just using it for email or chat compared to watching video. Why is that? its because watching video and playing games requires heavy processing thus consuming more battery. we should also remember that rechargeabu le batteries are consumable parts. it runs out in time. it is normal for it to degrade after a year. if it has'nt been a year since you purchased this computer then call acer and ask for a replacement battery. hope this helps?
thanks.
