These batteries give around 3 times the capacity & hence running time, of most NiCd types, without any of the "memory effects." This means that you do not need to fully discharge the battery before recharging, so you can safely just top it up.

Important Charging guide : (Read before use) 

Questions about charging are the most common things we are asked, so here are a few answers...
With NiMH batteries you DO NOT need to fully discharge them before recharging. It is perfectly OK
to just top them up after slight use.

The faster a battery is charged, the more heat is produced, a battery getting warm during charging
is quite normal & will not cause damage, but if the battery gets too hot, this could lead to damage.
We recommend that as a general rule of thumb the charging current should be no more than half
the battery capacity i.e. for a 2600mAh battery, it should be charged at no more than 1300mA.

 For larger batteries such as SubC sizes & above, the charge current can be up to the capacity, i.e. for a 3300mAh SubC cell it could be charged at up to 3300mA (But not the first 4 charges)

These are maximum ratings, it is
always best to go a little lower than this - it will improve the life expectancy of the battery. A good figure to go for is a quarter of the capacity (650mA for a 2600mAh battery) The first 3 or 4 charges of any new battery pack should be carried out at a lower current, this gives the cells chance to equalise, around 10 - 20% of the pack capacity is a good figure to aim at if possible.

The use of an automatic charger is best, as this prevents any accidental overcharging, this is
what can damage the battery, as once the battery has reached full charge, the energy supplied by
the charger is no longer being stored in the battery, but instead is being turned into heat & it is
this heating effect that will cause the damage.

We ask for payment or contact within one week of the auction close.
We endeavour to ship every order within 1 (working) day of being placed.
Unlike many of the products currently advertised on Ebay, these are shipped from the UK, and so in the majority of cases where 1st class post is selected, they will be received the day after we receive payment - just check our feedback to see this. We also offer a guaranteed next day carrier service for UK mainland destinations. If you require a guaranteed express service to other parts of the UK, please contact us first for an accurate price.
We will ship to ANYWHERE in the world – as long as the Royal Mail will let us! Buyers from Italy please note that we will only ship to Italy using the International Signed-For service, this is due to the very high levels of Italian buyers who claim that goods have not been received, if in any doubt, just ask for an accurate price.
Where payment is by cheque we usually ship straight away – we won’t make you wait for a week!
If you buy from any of our other auctions as well, please contact us for a combined postage amount, this will usually save you money over the way Ebay will calculate it, due to the fact that Ebay cannot apply postage discounts where items have come from different listings.
