Jedi single vs multi unit chargers

[P25Digital]

I've searched the archives, but couldn't find a discussion about the recent models of chargers.

I've recently been given the duty of maintaining my department's radios. We run primarily MTS and XTS series radios, no Impress batteries in service, just NiMH and NiCD.

My question is this...Is there any appreciable difference in charging a battery in the NTN7209A single charger or the NTN1177E multi unit charger? Charger cost isn't an issue that I'm looking at here, battery maintance and performance is the biggest issue. One of the NTN1177 multi unit chargers may also be placed in service in a mobile environment, power supplied by a stable diesel generator.

I've read about the power supply problems with the original NTN1177A chargers, but what updates have been made over the years with B,C,D,E versions? I'm not really clear on the NTN7209 versions either.

I'd like to find a primer on Motorola battery chargers and what was updated with each version. If anyone can point me in the right direction I'd appreciate it. We're an all volunteer agency and I'd like to stretch my communications dollar as far as it will go.

Thanks,

Jonathan

Johnathan,

Get yourself a "REAL charger". There are a few chargers out there that are WAY better than the OEM Jedi chargers.

AdvanceTec Industries pulse chargers and pulse analyzer chargers are available from Motorola for less than wholesale from the mfgr.

Also check out Cape international's line of drop-in chargers that use the advanced charger chips. Both of these operate from 12 volts.

I have been using Advance Tec chargers for years. They are down here in Miami. They work great & you can't overcharge a battery. They use adapters so the same charger will work for different batteries. GARY N4KVE

My AdvanceTec unit has two XTS plates and two Saber
plates installed. All of my non-Impres and non-Lithium
batteries are run through it regularly. Great unit.

Here is another alternate tri chem smart charger. runs on 12 volts with optional cord. With your choice of 'cups', $449 retail...

Thanks for the replies and input so far.

I have acquired a Motorola NTN1177E multi unit charger for a good price. I'm just trying to make sure that it is not putting more wear and tear on the batteries than one of our 7209A chargers would.

As money allows, I will look at the reconditioners mentioned for hall duty. In a mobile environment a conditioner isn't really practical. I'll need batteries that must be charged in the field back in service within 90 minutes or so, that's the reason for going with a regular multi-unit rapid charger.

Any thoughts about the 1177E vs the 7209?

In Ft Lauderdale, many of the Broward County deputies have a single unit Advance Tec charger in their cars with an extra battery on charge. They run on 12 volts. This way the deputy always has a fully charged battery. The deputies paid for them out of pocket. Cheap insurance. GARY N4KVE

A Motorola NTN1177E multi unit charger is HARD on batteries, just as most chargers made by Motorola up to very recently are.
