NiCd vs NiMH

[HailStorm]

Which has a longer runtime (if capacity is equal)? Which is the one that's less affected by partial discharge/recharge? What's a fair price to pay for an high mAh HT1000 battery (of either type)?

Thanks,
Ted

I like the 2700mah NiMH for my JT1000 /MT2000. I get all my batteries from KENDOO.COM $39.00 last time i got one. I have had very good service from them they don't get a memory problem. You need a slow and fast charger for NiMH batteries some times you can run them to low and the fast charger will not charge them.

1. By definition, equal.
2. In real life, it would be hard to tell, given modern, well-made NiCads.
3. About $70 for M batteries.

Is that saying that NiCads are usually the longer running ones? Or did I read that totally wrong?

[RKG]

Historically, NiCads were subject to a "memory effect" caused by some hard crystallization of the electrolyte paste if recharged before nearly discharged. Modern design and manufacturing techniques have all but eliminated this effect, though I still like to engage in sound battery management and periodic conditioning. Using M batteries, I've found you can get at least 500 cycles before the battery's capacity is reduced to 50% of nominal.

For Cold Weather the Cad Stands up a Bit Better.
Hydrid does not like the Cold.
We had the local groups put pockets inside their
coats to keep the batteries warm.

Works Great.
The hydrids are smaller by 1/3 to get the same
power as the cad.We only use hydrids now
but it is used with a conditioner and the life cycle is much
better.WATCH THE COLD "BAD"

When NiMH's first came out I got one for my radio and it worked great - so I ordered them for everyone else, about 30 radios. A disaster, I never leave my radio in the car -Arizona at 115 degrees today. Those that did leave them in the car (like all weekend) ruined them in less than 60 days. Motorola replaced them with NiCads - I kept mine and never had a problem - usually got about 2 years out of them.

I have been doing some extensive testing, Not Official though, Some of what I have found.

Using a XTS-3000 and Motorola NiCd NTN8297A We average 25 to 30 Months of service, before the battery will not last an 8 hour shift.
Very few waranty issues.

Using a XTS-3000 and a Battery Zone 4000 Mah MiMh BZ8297XX. We average 14 to 18 Months of service, before the battery gives a low battery alert. Some radios continue to operate 6 - 8 additional hours while in low battery alert condition. We have experienced multiple waranty issues with this battery. Most Common, failing to make good contact with the radio, second most common, a weak cell (low battery alert) I have tried conditioning, even though the conditioner reports 3500 mah or better, I get a low batt indication after 6 or 7 hours.

We are currently switching to the Motorola 3500 nimh RNN 4007AR, I have had no failures, and All good comments from the users so far.

The Air Force has standardized on the Multiplier M4007 at about 14.00 less, no problems with 8000 batteries.

Also Multiplier makes a 4000 MAH for the XTS also used by US Customs and Boder Security and Fema Excluslivly, NO PROBLEMS either

[MRFLASHPORT]

I also use the Multiplier 4000 MAH Batteries for my XTS3500 and they work great!

I have no problems what so ever. I get about 2 and a half days out of them.

I have 2 batteries with 1 on they way and 3 more for my MT2000!

W+W Batteries are a different story.
