I've unearthed this Olde Worlde handheld c/w CD-26 charger cradle and NC-88U charger. Simple plugging in overnight doesn't seem to achieve full charge, with Red charging light remaining on.

The unit is serviceable, with screen and both tx. and rx. functioning. The battery pack FNB-83 shows 8.39V when tested with a multimeter. The CD-26 charger cradle terminals show an output of 16.65V, whereas its label suggests an output of 7.7V 180mA.

Any informed guesses as to source of problem...?

Standard Horizon HX270E user manual (English - 32 pages)

Should be a link to a manual above. No idea if it is of use.

Obviously do not use the charger since it is outputting too many volts.

No idea why the charger is faulty. Sorry.

That handheld used Nicklemetalhydride batteries IIRC or accepts AA batteries if you have the cradle / holder to replace the NicklemetalHydride battery pack.

All I can suggest is:

1 Call customer services - they used to be great over the phone

2 source a second hand charger - there was one for sale on this forum.

3 battery pack may be old and due for replacement

4 splash out on AA batteries - they are expensive but give more volts than the NiMH battery pack and therefore the radio transmits for a longer time.

5 await a better reply

Hope I am on the right lines - I used to use that handheld IIRC - waterproof radio by does not float, dual ‘watch’ stations, quick button for channel 16 - great little radio imho.

I know it does not answer your question exactly and I have been criticised for such answers on here recently, but you can ignore my ramblings (as they have been called) of course. Perhaps I have written something of use and perhaps not.
 
I wouldn't reject the charger. Its rating is 7.7V at 180mA. No surprise that its voltage is higher at 0mA if it's a crude device. More likely that the batteries (or at least 1 cell) are shot. NiMH have a limited life. I would replace the batteries and see how it goes.
 
Hello,
FWIW, I have an old HX260 (model before yours, possibly 20yo) and the accus could not keep the charge, I opened up the battery tray and found 6 NiCd 1.2v elements with a couple of soldered leads to give 7.2v 700mAh.
Winter job I'll replace them with 6 NiMh possibly 2000mAh each, that will give a much longer operating time.
These kind of battery packs are quite common with car models, you may find one suiting the size of your case. Likewise, chargers for 7.2v NiMH are cheap as chips.

That is the quickest/best way imho. Unfortunately with that radio I left some alkaline AA inside their case for too long, they leaked and destroyed the metal contacts so it became useless. With my newer radio I keep the AA tray in a plastic bag together with four separate batteries, the whole inside the grab bag.
Cannot remember the number of things I had to bin because of leaking batteries, I eventually made a list of all the batteries I have to remove before iwntering: torchlight, headlight, magnifier lens, watch, baggage scale, thermometer, binocular, etc etc.
 
Is that 16.65v with nothing in the cradle? If so I'd measure again with the handheld in the cradle. Simple chargers give really weird open circuit readings in my experience.
 
Slight aside. I have an HX270. A while back l bought a replacement battery pack which are easily available as it is the same pack as used is other Yasu units. Genuine and OEM units are available but the genuine ones are reasonable cost.

Do we know why SH say not to use rechargeables in the AA holder? Are they just being over cautious or would it refer to using NiCads which were common when these radios were produced?

Hmmm. I inserted the h'held into the cradle and re-measured the charger's output there using some thin probes. Reading was 9.1V. 'White mans magic....'

I'll acquire an AA holder and some NiMH rechargeables as suggested above, and find someone better-informed than me who can do a proper test of the charger.

The maximum voltage is dependant on the charger power supply. Are you sure you are using the correct one as all mine are rated at around 12 volts.
Are you batteries definitely Yeasu . I purchased lithium batteries for mine and they worked beautifully however the manufacture had incorrectly connected the internal wiring to the rear terminals.I made up an arrangement that has worked for a few years

Many of Yaesu's later charge cradles with colour change leds definitely prefer the correct charge plug or one with a similar rating. 16 volts I suspect is above the normal rating.
 
Thanks to all for truly helpful guidance.

I'll chase up Cactus for some extra batterypack bits; and in the interim I'll just carry on using my Icom-M91D, which was a SIBS purchase.
