Rechargable batteries for Fishin' Buddy?

[hella356]

Hi. I have a FB 130 and I can't get it to work with NiMH batteries. It works fine with alkalines. It takes six 1.5v AA = 9V. However, NiMH are 1.2v. I was thinking of replacing the battery pack with one that holds eight AA, which with NiMH would mean 9.6v. Any suggestions as to whether 9.6v is too high?

Usually there's no problem substituting the lower voltage NiMH for alkalines. You might double check that all spring contacts are tight and that the NiMH are all charged right before your use. NiMH lose a great deal of charge each day. The low self discharge type (Eneloops) are by far the best in anything that will sit for awhile before use.

When I've tried the NiMH they have been fresh off the charger. They work for about 15 minutes before the FB shuts down. The same batteries work fine in other devices which is why I'm thinking maybe the 7.2v they are feeding it just isn't up to snuff.

I don't think that rechargeables have equal to Alkaline. I had a couple of musical devises (a microphone and wireless) that wouldn't work with rechargeables.

I just bought a Humminbird Fishin' Buddy 140c to use on my Outlaw Rampage. I scored 3 sets of 4 Eveready Ultimate Lithium AA cells on Amazon for $2.49 each, so I will have two sets of 6 (6 at a time in the FB). My experience with lithium AAs in the past is that they last at LEAST 4 times as long as alkalines. They also don't self-discharge and are 1.5V each.

Normally a 4 pack is something like $7.50, which makes them pretty expensive, but this particular deal on Amazon got me 12 of 'em for $14.41 including shipping. I think they will probably work great in the FB 140c.

Incidentally, I took the 140c out in the bright sun yesterday and it is much easier to read than the greyscale Humminbird 565 I have for my pram.

Oh, I forgot to mention that the lithiums are NOT rechargeable.
