You using the ni-cad or ni-mh? I think all ni-mh batteries lose 10% of their charge daily.
I also know a good brand name is important. I got some to use in the digital camera which was eating batties like candy. I had two sets, one in the camera and one freshly charged and ready. They were some off brand carried by WalMart. They soon did not keep a charge as long. Worse yet I had the rundown batteries swapped out and the run down ones were recharging. I smelled something burning and they were hot and the outsize of them had started to bubble up. Had I been out of the truck for a long locate they could have set the truck on fire.
I threw all them away and used a brand name. Wasn't the Tenergy but sure was no off brand name. Something like EverReady.

I use to buy Durecell Procell but after buying 3 boxes from Grainger (AA, C and D) EVERY ONE OF THEM WERE DEAD!!!!!!!!!!!
I know one batch of bad cells shouldn't ruin it forever but they did. Of course the switch out happened on the job when I found out. Half hour figuring it out and another half looking for a place to buy NEW BATTERIES!!!!!!
Energizer now. Never have had a problem since. Oh and I will NEVER buy from Grainger again.







We order ours thru Staples

We've always used Procell. An instrument guy once told me that consumer grade batteries (Duracell, Energizer etc) are designed to do what their commercials say they do - last forever. The problem is, that we use instrumentation that requires a consistent power supply to remain accurate.
Consumer grade batteries, as they are wearing down, will make my locators act a little wonky. It's happened to all of us where the battery indicator says you still have plenty of juice, but your signal is horrible, so you get frustrated. Change to freshies and it works well again.
Industrial batteries (Procell, Energizer Industrial) will work consistently and then, all of a sudden, the indicator goes from full battery to low no battery. One minute they work and the next they don't.
Some may say bullshit, but that's my experience.
Tenergy ..4years charging the same batteries..i said the same..paid 50 dollars for 8 d Tenergy batteries and the same 8 are still going strong after 4 years..ive saved alot of money with this batteries. How long does the procell last? are they rechargable?

Procell are disposable and they don't last particularily long. They work well, though. I have never had good luck with rechargeables (maybe because of our cold), with the exception of the RD 4000 batteries. They were only available for a while, and they were expensive ($1200 a set rings a bell), but they really worked well.
Tenergy, eh? I'm going to look into that....
Duracell Procells for me.
I seek not to know the answers, but to understand the questions.
