It depends on use. Some batteries last for only about 5-6 hours of talk time/app usage, while others average much more. Standby usage (no calls/usage) for mobile phones can last for several days without charge.
The batteries are over the counter watch batteries and they last twice as long as the battery put into the walker
Lithium batteries last longer on a full charge, but are non-rechargable. Nickel metal hydride batteries are rechargeable but won't last as long per charge as lithium. Which is better depends on your needs.
Depends on the quality of the batteries and the care that you charge them with.
On average you should receive 20 playing hours from batteries in your tape player.
Rechargable batteries will not last as long as normal AA's, but, of course, can be recharged, and should last over a year.
No, the PlayStation 3 batteries will not last forever. Even though they are rechargeable batteries, nothing lasts forever and the batteries will eventually stop taking a charge.
Olympus camera batteries last on average the same as other battery brands. To extend the charge life of your camera battery be sure to not use the LCD panel since it drains the battery.
Lithium ion batteries are supposed to last longer than nickel batteries. They do not lose charge for up to 10 years in their packaging, and they last longer while in use as well.
A set of NiMH AAA batteries can last roughly a month on a full charge if they are not being used at all and are simply allowed to sit around. In devices such as cameras and small pda's where rechargeable batteries are best used, the batteries can last nearly as long as normal alkaline batteries on a full charge. Exact times depend on the capacities of the NiMH batteries. A charge lasts long enough for a camera to be used normally for several days and hundreds of shots. As long as the NiMH batteries are not allowed to be idle and self-discharge, the life of a single charge is almost as long as a full alkaline battery. The life of the battery itself can easily be several years. NiMH batteries don't need much maintaining and can last for hundreds of charge cycles.
LG makes a great cell battery. You can also try Nexus.
I cannot definitely answer your question as I have no data on those specific batteries, however did you allow the batteries to fully charge before trying to use them? Many modern high capacity rechargeable batteries come with a small charge at the time of sale and if used in that state they will be permanently damaged. To prevent damaging them always fully charge them before using them (and this first charge will take several hours).
Battery life on mobility scooters can vary due to the frequency of use and charge time. The average mobility scooter user gets about two years out of the battery.
