who is to blame? my cordless phone was burnt by the replacement

I have a vtech cordless phone, the battery is dying. The original battery is Nicd, 3.6v 700mah.

I bought from ebay a replacement battery: NIMH, 3.6v, 1400mah, as soon as I put into this new battery, I smell the odor of burning, I later tested the battery, here is the result:

 

Original battery: 3.57v, 9.5ma (not clear of the unit, it is the reading from battery testing part of my digital multimeter)

replacement battery: 3.8v, 10.5ma

 

Please, experienced high hands here, what is wrong? Is that NIMH battery and NiCd battery not interchangeable? or just the slight difference on DC voltage? or what else? Thank you!

 

Here is the ebay link for my battery:

• 問題是，是否電池在某一瞬間，達到4.35伏或更高，可以充電後測一下。 -chat092- ♂ (0 bytes) () 01/21/2011 postreply 13:20:28

• 也可能充電器及電話電池都連在一起，NINH沒有起到降壓的作用， -chat092- ♂ (25 bytes) () 01/21/2011 postreply 13:26:47

• 樓主說，剛把電池放入，電話馬上就燒壞了。 -加州老李- ♀ (0 bytes) () 01/21/2011 postreply 13:29:09

• 即使電池沒有起到降壓的作用，也不應該燒壞電話。如果電池接觸不好， -加州老李- ♀ (87 bytes) () 01/21/2011 postreply 13:48:04
