These batteries have a capacity rating of 2450mAh, which is very close to that of the Eveready brand. In a Handheld PC without any accessories, they may provide similar performance as compared to other brands. This shows that the more you use your Handheld PC, especially with PC Cards, it's important to chose your batteries carefully to get the best performance. Many times, I'm told that rechargeable batteries seem to be too much of a bother. Note that rechargeable batteries don't make good spares.
Rechargeable batteries tend to discharge themselves much faster than non-rechargeables.
Of course, this is less of a problem, since you can simply recharge them. This is why we don't recommend rechargeable batteries as spares, since by the time you need them, they may be as dead as the ones you need to replace. As spare batteries, we recommend the Eveready Lithiums. They have the best shelf life. This is the term used for the reduction in capacity seen when you don't completely discharge the batteries before recharging them.
