Bought unit last year...when charging battery for 1st time this year red goes to green fairly quickly but only lasts a few minutes when using trimmer

Most chargers will show a green light when charged

That could take an hour

You have to or I do,charge all my items every 3 months

Not uncommon to have a failed battery in less than a year

Ideally four years & fair amount of use,but some do fail

Sometimes, the charger will overheat and fail. Try unplugging the charger overnight, plug it back in the next morning, then place the battery in the charger after waiting a few moments. Normally, this will correct the charging discrepancy.

I guess you've solved this by now, sounds like you need new batteries if the mower lacks power after trying to recharge. There are two sealed lead acid 12-volt batteries connected together on this mower to provide the 24 volts of power. These are the same batteries that are commonly used on rechargeable power wheelchairs and scooters. So you could find them at a Durable Medical Equipment company. The last two times I bought them, I got them from a DME company where I used to work. I also looked into buying them over the internet. Just make sure the replacement batteries are the same size and specs. You could burn out your on-board charger by continuing to charge batteries that are shot. I did this a few years ago with my 315.370270. Since then I have been charging the batteries with my portable Craftsman charger. The 12-volt batteries last about 3-5 years. I have had my mulcher since 1995 and have replaced the batteries about four times. This is the best mower I've ever owned. I'm going to retire it this year, if you're interested in it for spare parts.

Check that your charges is working - charge light on the unit or test output voltage. If these are ok, you will have to buy a new power pack for your trimmer or get a battery specialist to make up one for you. This will be by far the cheaper option.

It sounds like the battery is ruined. It may be best to replace the battery.

The battery will power your equipment for 30 to 45 minutes, that is normal. What you're thinking of is the lifespan of a lithium battery. It with your battery will last 10 times longer than a regular NiCad battery. So you will be able to charge the battery and use it Hundreds of times before the Battery Life is depleted. Sounds like it's working as designed

The green light on the charger usually indicates that the batteries are fully charged and you are ready to go. Does the controller show the batteries are fully charged? Can you operate the power wheel chair for several hours? If so, you are good to go.
When you connect the charger, if the light goes to red to green within a few minutes and the battery power does not last more than 1-2 hours or less, it may indicate that that the batteries will not take a charge anymore and need to be replaced.

Sounds like faulty batteries , take it back to the store where you bought it.

Batteries can only take a finite number of charges and they degrade over time.  A 1st gen IPOD is at least 5-6 years old.  The battery is probably bad.  You can buy a replacement battery from Sonnet Technologies (www.sonnettech.com).  It comes with installation instructions and is really easy to replace.

I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make. ****Time to replace them with new ones.**** Make sure you follow the mfgs charging instructions: "After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a recharge takes about 12 hours. Average talk time on a fully charged battery is about eight hours depending on environmental conditions, standby time is approximately four days." Good luck
