batteries!
I bought a hedge trimmer and a cutter both battery operated. Didnt use (medical reason) for 2 years. Now cant get batteries to take a charge. Have checked charger and engines, all okay. Is this normal? Any solution?

I don't know if this is similar at all, but a few years ago I was very ill for several months and my car didn't come out of the garage. After various attempts to recharge the battery, it turned out that it needed a trickle charger to get it going. -- -- http://www.shop.helpforheroes.org.uk/ |

If they have been allowed to discharge fully and then stay that way for a couple of years then they may no longer function properly. You don't say how long you had them before they were left unused - the batteries may just be old and need replacing. HTH Dave R -- No plan survives contact with the enemy.

Is this normal? Any solution? If theyre NiCd or NiMH they should have survived no problem. Its unlikely they're lead acid, but if they were they wouldnt be expected to survive 2 years flat. Lithiums arent very well suited to such treatment either. The only solution is a new battery pack. If theyre NiCd/NiMH, repairs are theoretically possible but last so little time that they're pointless. I'm assuming you've measured a suitable charging voltage on the terminals during charge. NT |

You don't say how long you had them before they were left unused - the batteries may just be old and need replacing. That's what happened with a disability scooter my wife has. The batteries had been flat for a few months. The manufacturer told her it would need new batteries at £80 each. I put the batteries on slow charge for a few days and then discharged them completely. This process was repeated until the batteries would hold the charge for a day and run the scooter for about five miles. That's all she needs. Steve -- EasyNN-plus.

However it would do no harm to leave them on charge for a day or two and see if they can at least partly recover, before laying out your money on a new set. Just check the charger from time to time to check that it's not getting too hot, which it might possibly do if the battery has gone short-circuit. That's unlikely though - they are more likely to have gone high-resistance and not accept a charge. |

But how does that apply to the OP, whose problem is due to putting his equipment into store for two years. I don't see any suggestion that those are 'scam' items. |
