Perfect fit..working very well !

I've been using these batteries in Vtech phones and they are holding the charge steady.

This cordless phone battery has 800 mAh rating where as the original battery is 300 mAh. The high the higher the milliamp hour rating the longer the battery will hold it's charge. A battery looses it's charge sooner than normal yet test good means that the battery mAh is weak. This means you have to charge the battery frequently. The battery is week and should be replaced. I cannot rate the battery life because I haven't had the batteries long enough to make that Judgement. Time will tell. Longevity I take as how long the charge will and that depends on how long you talk. That again is hard to judge because I don't talk a lot on the phone. But, it does hold the charge when taken off the charger and left sit. Note, don't leave the receiver in the charging cradle because that will weaken (shorten the life of) the battery. Beast to let the battery charge get to the recharge level (almost dead or dead) then put on the charging stand.

Works very well for our portable phones and much less expensive than store prices.
